Q Q Utopia

Projections into the future, the painting of a futuristic image or an utopian narrative can be based on a quantitative or a qualitative approach. A quantitative projection into the year 2100, for example, is form of creating an utopian vision of quantitative developments. Projecting the small reduction of working hours into a very distant future will eventually approach zero hours (tous sublime). Alternatively, utopian scenarios for qualitative characteristics of work and employment range from full health and safety or “cure yourself by work” (?really, “Arbeit macht frei”) to AI and robots designed to solve major laborious tasks and challenges for us. It is important to differentiate between the qualitative and quantitative forms of utopian visions. The time frames matter, too. In politics various combinations of utopian perspectives have frequently been combined. The human mind’s capability to project itself into the future explains our tendency to come up with utopian ideas or scenarios irrespective of our ability for rationality. We better acknowledge these human characteristics rather than insist on an either, or image of ourselves.

Good or bad

We have been taught by Shakespeare “to be or not to be, that is the question”. In political science we have pondered the question in a slightly augmented form. “to be good or bad, that is our question”. The basic image of women and men in society has been a subject throughout the history of ideas. For those who believe in the good nature of mankind, they tend to find reasons to believe that eventually mankind will find a way towards a peaceful cohabitation on our planet (there is no planet B yet for humans). On the other hand, each outbreak of violence and war are considered as a confirmation that mankind will always recur to some form of violence, even after extensive periods of peaceful cohabitation. According to the evidence presented by Meller, Michel, van Schaik, referring back to Kant, trade between people and nations is likely to prevent more violent relationships (p. 330). One of the major conclusions over the long term view of mankind is, that the periods of war have been far shorter and more rare than a focus on the last 3000 years seems to suggest. Maybe, “to be good or bad” is just a question of demographics of being too many at the same time in the same place.  Population growth and population density might be a powerful driver of “being good or bad”.  (Image: Delacroix, Last words of Marc Aurel)

Minds alike

Great minds, think alike. In the „propositions on happiness“, the author Alain mentions as inspiration for his thought process: Aristotle (XLVII) via Marc Aurel (LXIII) to George Sand (LXVI). This is an interesting perspective and abbreviation of the history of ideas. The impact of stoicism in his thinking of happiness becomes evident. Although originally he was described by another person as a relentless optimist, he was happy to accept this summarizing label of his personality. In his writings, that also may work as recommendations he stresses the importance to “know yourself”. That’s not an easy to achieve objective, as self-deceit is all to common.
However, in desperate moments or just on a rainy day (both are entries from Alain), you will need to know how to console yourself. Friendships and knowing how to please others become virtues, which contribute to your own happiness.
Perhaps the best summary of the history of ideas with respect to happiness is his last sentence in the paragraph “victories” (LXXXVII): “Le bonheur est une récompense qui vient à ceux qui ne l’ont pas cherchée.” In my own translation: Happiness is a reward for those who did not search for it.

Reason for war

In his “Propositions on Happiness”, the French philosopher Émile-Auguste Chartie, called in short Alain (1925), takes issue with the strange predilection for war. In his proposition XLII Agir, he writes on war: “Je crois assez fort que ce qui plaît dans la guerre c’est qu’on la fait”. In later paragraph   XLVII on Aristotle, he takes up his recurrent concern to explain happiness with the importance of agency in one’s own life and actions. “Faire et non pas subir, tel est le fond de l’agréable“. In taking both quotes together, we understand that for Alain the reason for war consists primarily in the desire to demonstrate agency. In order words, the position of power, of being in charge, being in control of the political situation are the prime reasons to go to war. With the first quote stemming from 1911 Alain had already a sound understanding of what would happen decades later in the 1st and 2nd World War. Even Putin‘s war in Ukraine is probably a cynic demonstration of agency in a seemingly otherwise rather paralyzed country. With this in mind, Putin‘s wars in the 21st century appear as another chapter in the endless pursuit of cynic reasoning. (Sloterdijk, 1983).

Cut it short

The “Revue des sciences humaines” (Demanze and Gleizes, Nr. 355, 2024 pp. 7-16) provides an interesting reflection on the widespread practice to find (new) ways to cut long stories or insights short. Short by itself, this introduction to a longer special issue on the topic “Faire court” stresses 4 elements of the contemporary impetus to cut it short:
(1) The creative process may be subject to condensation of content, similar to the process of a “reduction” in the culinary vocabulary. The speed of creativity, inspiration, freedom of expression are exemplified by the twitterization of and aphorisms in literature. Roland Barthes, in his analysis of the “haiku”, raises awareness to the different associations of the short text forms in different societies.
(2) The observed shortening of time spans of attention and the competition and economy of attention have raised the stakes for longer formats and explain to a large extent the success of shorts in the digital age.
(3) The short format works to increase the intensity of the literary experience.
(4) In deconstructing the associations of long formats as “monumental” versus short formats as ephemeral, the “cut it short“ tendency serves to “demonumentalize” the big shots of literature, science and the humanities. Well, about time to cut it short, “hic et nunc”, here and now!

Philosophy of Voyage

In an interview Claude Lévi-Strauss described himself as a philosopher of voyage. The excursions which lasted sometimes several months to live with indigenous people and study their languages, habits and culture became a scientific field of its own called social anthropology. He travelled with his wife and wrote down hundreds of notes and collected items. Only years later the concept of stuctural theory became evident to him. A voyage might go on after the end of traveling. It might start well before departure as well, not the least due to all the preparations. Colette, the French writer and polyartist, coined the phrase “ce qu’on sait faire, au fond, c’est de la route, ce  n‘est pas du voyage ” in the novel « La chatte ». In the pre- and immediate post 2WW years “taking to the roads” often had a gendered view of this with women being rare to hold a driver’s license. To “find meaning through voyages” or “the voyage is the meaning” fill whole libraries. For better or worse, travel books are still best selling books in a shrinking overall book market (less print books sold, but still higher value of sales).

Spring in Autumn

Can we have spring in autumn? Of course not, most people would answer. The definitions of spring and autumn are clearly defined as separate seasons. Depictions of the seasons in paintings in the Romantic or Impressionist periods are hard to imagine with somewhat blurred distinctions between seasons. And yet, climate change in the 21st century show surprising spring flowers in autumn across Europe. This leads to lots of confusion in nature’s time table.
From a life course perspective, we may ask, whether it is possible to experience a 2nd spring in the season’s view of the life course. More healthy years and spring feelings in the autumn of live have propelled a whole new industry around longevity and the mantra to “stay healthy for the wealthy”. The growing health inequality over the extended life course is a silent killer. The experience of spring in autumn remains a distant dream for most people with multi-morbidity.
Our experience of sequential or linear time, where one season follows the other, gets disturbed or at least blurred. The “Gleichzeitigkeit des Ungleichzeitigen” in English the “simultaneity of the non-simultaneous“ can be observed in the macro-world of everyday experience, albeit in a different way than Ernst Bloch defined the concept. On the other hand, it is no longer necessary to invoke Einstein’s theory of relativity or quantum physics to come up with apparently strange phenomena, but empirical facts allow us to question received wisdom, evidence based.

Racine Andromaque

The representation of Jean Racine’s “Andromaque” in Brussels at the Theâtre des Martyrs in 2025 has been an interesting choice, because the revival of a 17th century tragedy dealing with the intricacies of the Greek and Trojan war (mostly remembered for the Trojan horse). Jean Racine turned French theatre back to tragedies with his Andromaque (Résumé and analysis in French!), rather than the comedies or tragi-comedies of previous great authors like Molière.
The literary analysis of Andromaque by Roland Barthes (“Sur Racine”, 1963) identified 3 separate locations: chamber, anti-chamber and exteriors. The real power seems to live in the chamber as the place of respect, but also terror. (Compare also Mithridate). The anti-chamber is the place of diplomacy and the place of exchange of ideas, information and strategies. The exterior world is mostly closed off through walls or balconies as views from above. For Barthes this “symbolizes” even the prison inside or the pure heroic life inside the walls.
Besides this 21th century interpretation of 17th century theatre, Racine is remembered for his tragic love stories where A loves B, but B loves C and, maybe C falls in love with A. (Compare Robert Horville, 1991) The Condorcet paradox (Science of it) described only formally in the 18th century enlightenment, many decades later, had proven mathematically that such combinations of personal preferences are impossible to resolve. Hence, these confusions are great stuff for tragedies to evolve live on stage.

Social Anthropology

Dina Dreyfus, married several years to Claude Lévi-Strauss, has shared with Claude the long anthropological expedition to Brazil in the 1930s. They jointly studied the social organization of indigenous people across Brazil. Their abundant notes of field studies have now been digitized and the BNF is making this accessible.
Additionally, an exhibition on these field studies reveals the close collaboration of both partners. Returning to France in 1939 meant that soon after the return due to their Jewish decent had to interrupt their academic careers in France and some notebooks were lost during the Nazi occupation of France. After the war both separated and Claude Lévi-Strauss embarked on the drafting of the structuralist theory, Dina became influential in the field of the philosophy of education and teaching philosophy herself.
Besides all these lasting achievements, the exhibition shows the typewriter which had accompanied them for many years. The German language layout is quite remarkable as this asked for an additional mental versatility in putting their thoughts and experiences into the form of a manuscript. According to Claude Lévi-Strauss the use of this technical device allowed him to detach himself emotionally from his analytical work.

Ethics in Photography

Yes, you read this correctly. This entry is about the ethics in photography, not about the much more popular discussion about the aesthetics in photography, which fills thousands of books on fashion, architecture, minerals, flowers, animals, landscapes and … you name it. Sensationalism works in photography. The more spectacular an image, the more likes you’ll get in any media, social or so-called social as well as traditional ones. Sex and crime are popular subjects, better framed as objects, as well. The basic idea of what constitutes unethical imagery or photography is broadly defined by the principle of exclusion, i.e. what is not ethical in photography. Let’s add to this inventory the conditions of production: exploitation of the subjects, be they persons or animals or even authorship like violations of intellectual property rights by AI.
Regulations and legal frameworks clarify many of those issues, enforcement of these rules are yet another element related to the ethics in photography. Global warming and the loss of biodiversity has made us aware that the respect of natural resources is also an aspect in the ethics in photography. Travelling long distances by plane just to get a few shots in the Himalaya region, if there have been thousands of (better?) images produced, printed, distributed before, is not sustainable for our planet as a whole. Invading protected areas, like natural bio-reservoirs, to take a few shots especially of rare plants and flowers maybe nice to look at, but the longer-term consequences add up to a loss of biodiversity for us all, in particular for later generations.
These considerations are different from “aniconism”, because they originate in a humanist foundation of ethics not concerned with any depiction or idolatry of images. The historical roots of any ethics in photography have long shadow into today’s practice of photography as well.

Marc Aurel Memorials

The depiction of Marc Aurel as Emperor has become a trade mark in the history of art and politics. As an emperor with good horse riding skills, Marc Aurel was the first emperor to be portrayed as riding on a horse without saddle whilst, of course, in perfect skill to master the horse and give orders or strategic commands. Many subsequent emperors, Napoleon or Friedrich have had their power positions “immortalised” as such, which served at the same time to make them appear taller and “in command” of something.
Travelling by horse has  also been for a long time the fastest mode of transport, yet another symbol of social status used in media campaigns of those times. The memorials in honour of Marc Aurel had already during the ancient time the function to transmit an image, the emperor wanted history to keep in mind, rather than the view of ordinary people in the Roman empire. Memorials of political leaders have been a demonstration of power for centuries before and for centuries to come.

Marc Aurel critics

In the literature on and about Marc Aurel (Brenan 1882, pp. 484) the end of the ancient world is mentioned frequently. This refers to the beginning of the end of the Roman empire and the rise of Christianity to be become more influential. What caused the decline? The nepotism in the governance structure through the placement of family members to influential positions and as successor alienated many followers who previously believed in the high moral standards advocated by Marc Aurel.
Justifications of superiority by social origin are standard at the time of writing, but Marc Aurel did not see the potential of a more equitable distribution of offices. Women were relegated to subordinate or no public positions and are not mentioned with respect to  the importance of reasoning or social competence either, none but one in his acknowledgements (Book 1). The discrepancy between the formulation of virtues as well as ideal standards versus own practices of hierarchical leadership, recourse to slavery and brutal upholding of the empire should not go unmentioned.

Marc Aurel Advice

The study of Marc Aurel’s Meditations offers advice on how to conduct one’s private and public life. The role as advisor or teacher is an important part of his writings, albeit quite indirect. In going back to Book 1 and his acknowledgements of his own advisors, teachers and good examples indicate the motivation and intention to write down his meditations. “People exist for one another. You can instruct, or endure, them” (Book 8, paragraph 59, see also Barrientos 2020). Marc Aurel does not shrug away from the treatment of general concepts of humanity like justice. In his view “… justice entails the exercise of wisdom, kindness, and fairness in our relationships with others both individually and collectively.” This includes already tolerance as a part of justice as in Book 4 paragraph 2, according to Robertson (2020). The idealistic view of humanity, following Platon’s philosophy and other Stoic authors, still serves as a benchmark against which many leaders are measured today (compare Le Monde 2025-9-25 p. 26).

Marc Aurel Book 12

The closing book of Marc Aurel’s Meditations is taking issue with his own posterity. As a guideline for others, he formulated the claim not to care so much more about the opinions of others, but to stand by own reasoning and trust in one’s own opinion. “I have ofetn wondered how it is that everyone loves himself more than anyone else, but rates his own judgement of himself below that of others. … So it is that we have more respect for what our neighbours will think of us than we have for ourselves.” (Paragraph 4, Penguin Classics).
Of course, in the age of “philosophy as discourse” (Habermas), we are used to criticism of books and their authors. For the emperor philosopher this was less obvious, albeit the Socratic tradition of exchanges between teachers and their scholars was a kind of precursor of 20th century philosophy.
His writings in ancient Greek, however, remained little known and debated until its first Latin publication. Ever since, it has been a prominent work on ethics and leadership. The exhibition in Trier featured the copy of Helmut Schmidt, as the long reach of stoic writings on virtues and leadership.

Marc Aurel Book 11

Throughout the Meditations, Marc Aurel concerns himself with the idea and importance of the common good. Based on his experience as Consul and Roman Emperor, the common good is of primary concern. At least in his thinking and writing these concerns play a very prominent role just like the “social“. In order to ensure his own successor, as described by Katherine Kennedy (2020 through www.classicalwisdom.com) he was only the 2nd Roman Emperor  to appoint a biological heir as his successor, which met a lot of criticism already at that time. Nevertheless, in his philosophical thinking and leadership guidelines he cherished the common good above all. “Have I done something for the common good? Then I too have benefited. Have this thought always ready to hand: and no stopping.” (Book 11 paragraph 4, Penguin Classics edition). This is in contrast to the predominant utilitarian thoughts many centuries later where the pursuit of your own benefit will further the benefit for society. The reversal of the logical sequence in later thoughts is particularly remarkable as well. The process of individualisation seems to be another additional factor in the lack of concern for the common good in the 21st century. Raising the awareness to further the common good is a continued challenged in most societies.

Marc Aurel Book 10

Book 10 offers some referrals to previous books and topics: Marc Aurel defends a wholistic vision as in book 10 paragraph 17: “Keep constantly in your mind an impression of the whole of time (χρόνον) and the whole of existence (οὐσίαν)…” (Penguin Classics version, also in Greek original/French translation). In the same vein, he wants all this knowledge and considerations to be “actionable”. This reads in his words: “No more roundabout discussion of what makes a good man. Be one!” (book 10, paragraph 16 in the same two editions). As the late Marc Aurel’s writings progress, he becomes even more “exigent” in the sense of demanding ever higher standards (of himself). “Whole-ism” paired with a request to, nevertheless, be ready for action at any time is not only a high cognitive demand, but also a reminder to leave procrastination behind. The virtue of a stoic leadership style remains an ambitious challenge.

Marc Aurel Book 9

For students of economics or business the paragraph 10 provides an interesting precursor of the concept of capital, interest and maybe even on human capital: „Man, god, and the universe all bear fruit, each in its own due season. No matter if common use confines the strict sense of ‚bearing fruit‘ to vines and the like. Reason too has its fruit, both universal and particular: other things grow from it which share its own nature.“  (Penguin edition) There are so many examples of the fruits that have grown on the trees of knowledge that we have become accustomed to the idea and continue to reap the benefits of those vines. Of course, some of these fruits have turned out to be more of a curse than a blessing. We seem to neglect the wise judgment which Marc Aurel mentioned along with the use of logic. (Also in this version Link)

Marc Aurel Book 8-9

In book 7 paragraph 38 the stoic wisdom is exemplified in the the the short phrase „If you have sharp sight, use it: but, as the poet says, add wise judgment“. Being sharp in your reasoning or data collection is only part of the human endeavor. A wise judgement is, however, an ambitious aim as judgments have different short term and long term consequences. Intergenerational considerations as for climate change ask for respect of other species, biodiversity and to take into account very long time horizons.  The quote from book 8 paragraph 5 appears very modern or post-modern in this context. „There can often be wrongs of omission as well as commission.“ (both citations from Penguin Classics edition) Not acting on behalf of future generations and disappearing species is the most crying omission of our time.

Marc Aurel Book 7

In paragraph 63 Marc Aurel refers to Plato as one of his sources: “No soul”, says Plato, “likes to be robbed of truth” ( and continues himself) “– and the same holds of justice, moderation, kindness, and all such virtues. Essential that you should keep this constantly in your mind: this will make you more gentle to all.” The remarkable reasoning is to transform the own generalized experience into a behavioural recommendation. It may be argued that Marc Aurel starts from a kind of Aristotelian empirical study of persons in different life domains to derive an empirical fact. Based on this he develops a more Plato inspired “idealistic picture of mankind”. He is very much preoccupied with the philosophical question, how is a good life for all possible. In a previous paragraph (55) he outlined his 3 guiding fundamentals: (1) “The main principles in a man’s constitution is the social; (2)… resistance to the promptings of the flesh, like impulses; (3) judgement unhurried and undeceived”.
With such a claim for a “rational constitution” of man, he puts himself into the footsteps of previous philosophers of the ancient Greek tradition and, therefore, his writing in Greek rather than Latin is also a homage to this philosophical heritage.

Marc Aurel Book 6

Some passages of Book 6 can be understood like quotes of much later works, even like writings of the enlightenment period. Take this one: “If someone can prove me wrong and show me my mistake in any thought or action, I shall gladly change. I seek the truth, which never harmed anyone: the harm is to persist in one’s own self-deception and ignorance.” (para 21 in Penguin Classics version, also in Greek original and French translation).
The same passage in historic English: “If anybody shall reprove me, and shall make it apparent unto me, that in any either opinion or action of mine I do err, I will most gladly retract. For it is the truth that I seek after, by which I am sure that never any man was hurt; and as sure, that he is hurt that continueth in any error, or ignorance whatsoever.” (Para XX in Gutenberg.org online reader).
Why is this already an enlightened vision of truth? In the search for truth, he is open to criticism or doubt by others (maybe even irrespective of societal standing) and, moreover, ready to change his conviction and action. Religious doctrines of the time and many centuries after his writings would not have accepted such a doubtful mind who might change due to (scientific) reasons. Long before “Cogito ergo sum” (René Descartes, (1637), I think, therefore I am, of the early enlightenment, Marc Aurel might be summarized in this paragraph as “Cogito, ergo dubio”, I think, therefore I doubt – and I may change accordingly.

Marc Aurel Book 2-5

There are several translations of Marc Aurel. In the Shakespeare English translation from the Greek original of the Meditations a passage (Book 5 paragraph XXIII) describes or idealises humans as a “reasonable and sociable creature, regulated and directed.” The same short quote of this paragraph in the English translation by Martin Hammond (Penguin Classics p.43) reads: “…my wish is to follow the nature of a rational and social being.” Of course, both translations are pretty similar at first glance, but the difference of “reasonable” versus “rational” and “sociable” versus social” mark very important differences that had and have different impacts throughout the following centuries up to today. As in many other instances going back to the original version in Greek (book link) might clarify the issue, however, the entry barrier is access to the bilingual version and use of an ancient Greek dictionary.
With almost 2000 years of advances in rational approaches and its tools like mathematics, the scope of the rational is huge and the behavioural turn in the social sciences demonstrates the limitations of human’s use of rationality (λογικός) in decision-making. Reasonable seems to come closer in today’s “post-enlightenment” world.
There is also quite a divergent connotation in the simply “sociable” (κοινωνικός) being or the “social” being, which has a wider scope attached to it. Hence, lets be aware of the implicit interpretations of translations. For a start the parallel reading of translation and original (Link) might enhance our understanding and spur even new translations and interpretations, which speak with the classic originals to today’s audiences (with or without AI).
A witty joinder of both previous translations is “And my will is the will of a reasonable and social being”. (Link Book V, paragraph 29 bottom).
From the Greek to French in book V (Link)  with an even broader understanding of the social as “la société universelle”.

Marc Aurel Book 1

The reading of Marc Aurel’s Meditations in its Book 1 offers first of all his acknowledgments of people who had a lasting impact on him or offered learnings to him. He presented these learnings or take-home lessons as we call this nowadays in a style of “positive psychology”. This means writes about the positive influences and which kinds of positive behaviors he saw in living examples of others and which he felt were particularly worthy of general consideration. In philosophical retrospect we might read the book 1 as a list of “categorical imperatives” which would make a decent life feasible for all. His acknowledgments start with 1 line on his grandfather (decency and mild temper), 2 lines on his biological father (integrity and manliness), 3 lines on his mother (piety, generosity, avoidance of wrongdoing and simplicity of living), but 4 lines on his tutor, even more on other advisers, 20+ on his adoptive father, which is more than on “the gods”.  All these experiences impregnated him with a sense for a “ruler’s responsibility for the common good”. (p.8). The stoic virtue lies in the extensive list of positive contributions from others to make him the rather unique philosopher and emperor.

Marc Aurel Philosopher

2025-9 marks an additional landmark in the achievements of the late Marc Aurel. In the Roman built city of Trier, 3 museums offer exhibitions on the life, ideas and imperial governance style of Marc Aurel. Libraries and bookshops around the city portray a wealth of books and studies by and about Marc Aurel as well in many languages (image below 2025-9). The stoic author and practitioner has served as an example of a leadership style which became for many subsequent leaders a hard-to-achieve precedent. The writing style of Marc Aurel in short paragraphs and aphorisms proved highly accessible, although his readership swell only after a Latin translation of his Greek original appeared in the 16th century. The title “Meditations” in English, “Pensées pou moi-même” in French or “Selbstbetrachtungen” in German demonstrate the difficulty to get to grips with the author’s intention and objectives in writing down these reflections on life, ethics, humanity and good governance. Through the use of Greek rather than Latin he puts himself in the line of Greek philosophers rather than the succession of Roman emperors. As the numbers of bad leaders still outnumber the good governance style advocated by Marc Aurel, these exhibitions in the Simeonstift, the Landesmuseum and the Stadtbibliothek are a perfect opportunity to demonstrate that good governance is something that can be studied and learned even in the distant Roman history.

Photographe engagée

Marie-Laure de Decker is featured in the “Musée européenne de la photographie” (MEP) as a photographer committed to capture truth in situations of conflict. She started her career with documentary photos from the Vietnam war. Rather than searching for spectacular scenes, she succeeded in her attempt to capture the more emotional and, therefore, relatable moments for her various audiences. With a firm commitment to the human in her work, the photos by Marie-Laure de Decker reach a level of extraordinary sensitivity to what it means to stay human in violent situations and even military conflict. The portraits of politicians, workers, professions and famous actors applied the same approach. Rather than days or weeks Marie-Laure de Decker spent months or years in the regions of her documentary photo series ranging from Vietnam, South Africa throughout the apartheid regime, Pinochet years of dictatorship in Chile, the 2 parts of Yemen to a prolonged stay in Chad.

The exhibition in the MEP in Paris curated by Victoria Aresheva  raises awareness to the additional fact that photo journalism became an affordable profession only after specialized agencies were created that granted authorship rights to photographers, which ensured later use of their work in edited volumes as well as working for several newspapers or magazines. (Image: Marie-Laure de Decker, self-portraits, MEP Paris exhibits 2025-8).

Less but better

There are many examples where a new mantra for the 21st century emerges from recent scientific evidence: “Less, but better” (Lbb). In studies of nutrition and human dietary requirements, the importance to eat less has been demonstrated on a regular basis. And this is even more important than to do more exercise if weight loss is the target or the attempt to explain obesity across the globe (McGrosky et al. 2025). The case for eating less is strong. Eating better refers to the need to avoid unhealthy, toxic or cancerous food or the way to prepare food. “Less but better” could become the new mantra or “categorical imperative” if you like it more philosophical in tone. We, the people gain, and the planet will gain as well. It is an easy win-win case, albeit with some behavioral implications.

Aufklärung Enlightenment

The period of the enlightenment is a historically defined time period of the late 17th and the whole 18th century. Although often associated only with Europe as its origin, the American contributions and influences have been far-reaching as well, just thinking of the “Declaration of Independence“. This historical period is, however, most interesting through the unrivalled contribution and pivotal point to the history of ideas. The exhibition and catalogue on the “Aufklärung – Enlightenment” by the German Historical Museum in Berlin exposes many of the historical editions of books that “made the enlightenment”. Philosophical writings and readings (Immanuel Kant: Kritik der …) of the period (especially in German) are tough even for native speakers of German, unlike reading of French (e.g. Jean-Jacques Rousseau) or English (e.g. John Locke) contributions to the enlightenment. Maybe this is already one of the reasons why in France the revolutionary ideas were put into practice through population-wide political movements.
The historical period of the enlightenment came to a close in the early 19th century (1806 another pivotal year). The English or French terms of enlightenment or lumière maybe be interpreted in a way that other historical periods like the medieval ages were periods of darkness, even later periods again did not live up to the idealist prerogatives of the evolution of humanity. The German term “Aufkärung” has its etymological roots more in the action associated with “to enlighten”. This hints at the continuing process of the ideas of the enlightenment in modern terms the process of individualisation, tolerance and autonomy.
There many valuable short interviews shown in the exhibition and Jürgen Habermas contributed a short closing statement to the catalogue of the exhibition on the unfinished project of the “Aufklärung” inviting us to continue also with the “Kritik der Aufklärung”. After all the enlightenment did not save us from repeated events like “Apokalyses“.

Präludium Prélude

Learners of how to play the piano are likely to pass the composition of J. S. Bach entitled Präludium in German and Prélude in French. Maybe that influences the approach to the piece of music. The title sounds different in each language. It is interesting to follow the Präludium Prélude throughout the history of composition. The pianist Jan Lisiecki has just recorded and released a disc with Deutsche Grammophon following the historic evolution of this genre. The rather easy-going beginnings by Bach (see below for extract of first motive) have turned out to become rather complex preludes with subsequent composers. We may ask ourselves at this occasion: a prelude to what? Your own associations are welcome. In international politics we can observe strategic movements of countries and their military equipment as a prelude of war, but also of peace. Small aggressions may turn into wars. In philosophy Nietzsche praised the dawn (Morgenröte) and focused a lot on new beginnings. Composers might be the best forecasters of what is to come in the following years. Certainly the preludes have foreshadowed some of their later work. Nowadays, many LLMS in AI build on algorithms that predict what is the next word to write or task to do. Even in composition AI is moving ahead fast. Hence, we e are likely to study preludes much more for several reasons now.

Biography Memorial

Some biographies take the form of a memorial. Marie-Luise Conen and Zdravko Kucinar have erected a memorial for the researcher, author and Social Demokrat “Milian Schömann” from the “Moselle” region near Traben-Trarbach and Lösnich. The biography reads like a narrative of crimes, which goes without punishment, before and during the Nazi-terror and the power grip in rural areas in the late 1920s and early 1930s. Milian Schömann achieved his university entry qualification A-levels in Traben-Trarbach before he moved on to study German literature and philosophy in Heidelberg, Bonn and Berlin.
His studies and political engagement were driven by a humanist approach and his letters and publications as literary critic as well as his contributions to philosophy are partly reproduced in this biographical account. This allows to follow in the footsteps of the curious and open-minded person of Jewish descent. As a contributor and speaker at meetings of SPD-members and associated political movements, he risked and eventually lost his life for his humanitarian convictions in 1942 near Belgrade.
It is the merit of Marie-Luise Conen and Zdravko Kucinar to let Milian Schömann live on in our time through the reprinting of some of his work, which is embedded in a  well-written historical account of the political and family setting at that time. The professional psychological training of Marie-Luise Conen helps to reproduce the anxious atmosphere Milian Schömann has lived through, albeit he remained a productive writer despite the economic hardship and living in exile.
This biography accomplishes in a rather unique way to enter into the mind and thinking of the author Milian following his very personal perspective on the “history of ideas” and inner call to action. Similar to the appreciation of Viktor Ullmann in the Jewish Museum in Berlin, where the music of the composer lives on after his death, the writings of Milian Schömann survived extinction, despite that he was murdered. After more than 80 years we still feel the loss of potential other contributions to philosophy and literary studies. The recognition extends to Milian’s academic and personal mentors Oskar Walzel and Arthur Liebert, important sources to understand the reasoning and motivation of Milian.

Beyond ART

Is there anything beyond art? Well, maybe there is. ART in German language is an abbreviation of “Allgemeine RelativitätsTheorie”. In other words the General theory of relativity developed by Albert Einstein is in its shortest form a one line mathematical expression, but with lots of equations included in the general statement, which grew out of his much earlier special theory of relativity. The textbook by Michael Ruhrländer provides a step by step approach to get to grips with the mathematics involved to reach a better understanding of what “ART” is about. Take your time to digest it and brush up a lot of maths beyond your A-level maths.
The abbreviation ART suggests a lint to art in popular understanding. Indeed, it needs able artists to show insights of ART to more people than the restricted scientific circles. An understanding of a 4-dimensional system of time-space has some more accessible features than waves of gravitation and the many puzzles that can be solved through ART.
Decades later quantification has build upon ART and takes us further into fabulous world of mathematical and physical imagination as well as real world applications.

Wave and Particle

The history of ideas in physics has been evolving or revolving a lot around the wave-particle-duality. Even if the basic debate by now is about a century old, we still need to come to grips with this challenging notion that light is not just a beam and nice colors through a prism yielding a spectrum of frequencies, but it can emit material matter called photons that have a non-zero value(s) of energy.
Max Planck came up with the formula E = h × f, where h is the Planck constant, E the energy and f the frequency of the photon. The synthesis of Einstein’s light quanta and De Broglie’s matter waves became the foundation of quantum mechanics.
The exciting evolution of physical ideas results in the state of the “art” view that, for example, light can take both forms, wave and particle, at the same time. Quantum mechanics has become a thriving field in physics and is currently transforming the world of computing in the 21st century. The amounts of funds invested in the race of applications of quantum computing across the globe are “astronomic” and have become part of dual-use spending of research funding. Encryption of information or access codes are of growing importance for civil (banking, mobility, health info) or military purposes. The speed of quantum processors will allow cracking of codes much faster and therefore new dangers are looming in many fields. It is a rather competitive field, which has evolved a lot from the original wave and/or particle vision of the world (of physics).
For social scientists there are several examples of applications of the concepts of quantum mechanics to social and behavioral sciences (Link 1, Link 2). Hard to predict, whether the wave and/or particle view will dominate the social applications of elements of the history of ideas in physics. New concepts in science challenge our traditional science-based thinking about time, space and space-time with implications even for our understanding of causality and covariance.
