In family histories we like to look on tree-like linking structures. Most frequently the choice is the descendant perspective (Top down). X, Y, Z have been the children of A and B and so on for a couple of generations. Bottom-up perspectives are equally feasible and modern patchwork families have more widespread representations of their families. Those representations were easy to do as families were lifelong bonds. Shorter family bonds, previously mainly caused by pre-mature deaths, are more common as people might have different partners and off-springs at different periods of their life course. Drawing family trees then looks more like a network structure of several families. History and literature is full of stories of how families aimed to keep their genealogy simple to the outside world. Modern days are no exception to this. Law had to adapt to these societal facts and changes thereof. Comparing decades over the last century there is, in my view, the remarkable trend to allow for more complexity in family histories, even after the 60s leading to many complete ruptures of family ties and links throughout the 70s and 80s.
With reducing fertility rates in most, not only western regions of the world, medical demography is back on the agenda. Similar to family trees, new forms of identifying promising pharmaceutical products have moved to more data-driven disease insights. Historically the local medical doctor had an overview about the likelihood of diseases following family’s medical histories over generations. Data-driven analyses, supported by data analytics and/or AI support, can learn permanently about potential and actual risks. New links of diseases are discovered this way extending the family doctor’s view of risks to watch out for in patients. Additional remedy and marketing potentials of existing drugs are also detected this way, beyond anecdotal evidence. Research published in the “Journal of biomedical semantics” by Vlietstra et al. (2020) classifies disease trajectories to construct knowledge graphs of biomolecular interactions. What previously a medical doctor in region could infer from his medical records in a less systematic way, can now be analysed on big data sets of countries, continents or even the global scale. Data is knowledge, and some already know, that this data-driven knowledge is worth a lot of money. Linking previously and seemingly unrelated facts or events, just like becoming aware of more complex family trees through DNA-analyses is the medical part of history. How we deal with this as families or societies as a whole, is the trickier part. Structural changes of societies are marked by decades-like changes, but specific events like “Fukushima”, Tschernobyl or other man-made rather than natural disasters have created new forms of contamination and the spreading of it. In addition to family trees we need broader consideration for knowledge bases to demonstrate, for example, the spread of cancer in the networked society. Additionally this evidence should have a stronger recognition in courts as prove of contamination lines. Statistical reasoning is more likely to become court-relevant. Hence, train the legal profession beyond what “statistical discrimination” is like. Causal mechanisms are manifold. Some are more likely than others. Semantic knowledge graphs remind us of the presence of reverse causality many relationships. Scientists need an optimistic state of mind to abstract from many intervening processes on health, be they tiny micro- or bigger macro-level societal effects. 
Photo K
The self portrait is a timely topic for an exhibition of photography. As part of the European month of photography (EMOP), the PhotoBrusselsFestival offers a good overview of what photography deals with in the 21 century. The Korean cultural centre (KCC) in Brussels has a long tradition to serve as an exposition in the centre of Brussels (Sablon) and is joining this year’s photo festival. The 2023 photography festival has the “Self-Portrait” as a guiding theme. Rather than entering the debate about “portrait chosen or portrait endured” (Photographica 5,2022) the self-portrait has more degrees of freedom in it. Even if it is apparently a choice to portrait oneself, there are ample examples, where the urge to produce a self-portrait is part of a wider concern for fundamental issues.
The exhibition of 5 artists from Korea at the KCC invites us to reflect on the pervasive self-portrait practice all around us. The self-portrait is not only a tool of self-reflection, which has a long tradition in art (just think of a famous drawing by Albrecht Dürer of himself), but self-portraits are also pervasive on media and social media today. Additionally, the self-portrait is a powerful tool of thinking and imagining yourself at various stages of the life-course. For centuries it had been a social or political privilege to have your portrait taken. It still is to some extent, but only if the person taking the photograph, has a special reputation. In a market difference to the selfie, the exhibition of artists in the KCC highlights the process of self-reflection that is part of creating the portrait as well as the ensuing reflection by the spectator. In looking at the self-portrait of the photographer, we might involuntarily deal first with our own perception of the image. Danger, dreams, fantasy, sorrow, pain, self-assertion and reconstruction of the self, all these themes come to mind when confronted with the self-portraits of the 5 artists (Bae Chan-hyo, Jeong Yun-soon, Lee Jee-young, Ahn Jun, Choi Young-kwi).
KCC director Kim Jae-hwan names this collection, curated by Seok Jae-hyun, “An odyssey of images leading to self-re-flection”. In referring back to the protagonists in novels from Hermann Hesse, he points our attention to the “unique journey through images as they find themselves”. To embark on the journey visit KCC in Brussels, ask for a copy of the catalogue or start by reading the title of the exposition: “Who Am I” – it is apparently no longer a question after the journey. Is it for you? More reflection on images and photos here. 
Art Un-Fair
The Brussels Art Fair (Brafa 2023) with its long tradition is certainly a major highlight in the world of art in Brussels. In view of the languages spoken at the fair, mainly French and Dutch, some English with here and there a word in Spanish or German, the international reach is probably still not at the level of before the corona crisis.
The availability of established, internationally recognized art over many centuries on the art market is remarkable. Whereas before the crisis speculators bought art to shield their fortunes from a high inflation and/or politically instable period, nowadays it seems to me, that some art is returning to the market due to the need for liquidity of speculators or risks of confiscation in case of dubious previous acquisitions or ownerships. Renowned galleries, of course, provide impeccable certificates or information on them, a tricky business in itself. Anyway, the tour on the fair is a “parcour” through the history of art, mainly through the Western or European arts across centuries rather than decades. Most persons will find splendid examples according to their preferences of art ranging from paintings, sculpture, prints or other artefacts. Beyond the impressive individual art work, the arrangements and “mise en scene” of art is another learning experience at the fair. Whereas most public museums are happy to make accessible as much as they can of their collections and archives, the private art market has another objective. Effective and convincing presentation of the artefact is likely to “enrich” the value of art work as well as the seller and the dealer. Technology allows great lighting and some otherwise “sombre” artwork becomes a shiny little piece catching eyes, hearts and wallets. For some visitors it works probably the other way round.
For persons overly stimulated by art, I recommend to close the actual or virtual visit with a look at the little bit cheeky artwork presenting Belgian chocolate next to royalty (Gallery Delaive, showing Peter Anton’s “Paradise Variety” next to Andy Warhal’s depiction of a Queen, see below or their Instagram presentation). A sublime moment to repeat the experience at home at moderate prices with your very own box of chocolates. At a price of 10€ each box you can enjoy roughly 2000 of them for the price of the art work. The question is: What is more healthy? Think about mental health as well. Alternative question: Art on a Fair is fair, unfair or fair traide? 
70s
In autumn 2019 the Cosmopolitan featured a headline “Stop fighting it: the ´70s are back”. At least in fashion the 70s are still with us. Platform soles, moon boots, hot pants, all had their first appearance in the 70s. We keep seeing them in fashion shows even 50 years later. In politics, the retreat of the U.S. from Vietnam in 1972, with more than 50.000 killed soldiers from the U.S. and many more Vietnamese persons, is certainly a success of the sizable activists’ peace movement of the 60s. Willy Brandt’s kneeling in Warsaw in front of the heroes monument in honour of the Warsaw ghetto marked the beginning of a reconciliation with Eastern parts of Europe.
The oil crises 1973 and 1979 caused mass unemployment and from the beginning of the 70s “Greenpeace” started its on-site activist approach against nuclear weapons, killing of whales and dumping of toxic waste. The network of independent organisations is contemporaneous to the invention of e-mail between large so-called mainframe computers using the now common address format x@y.z. The feminist movement achieved major successes with a UN resolution to ban discrimination against women. The male dominated aggressive and excessive punk movement occurred almost in parallel. New products like the Polaroid camera for instant photos and prints, video cassette recorder, the chopper bike “Bonanza” as well as the collapsible Maclaren Buggy for children defined a lifestyle around a more mobile society. Plastic furniture, bright colours with uncommon combinations brought with it a more diverse culture. Societies exploded into different lifestyles. Some taking the new Concorde, so-called supersonic speed delta airplane between Paris and New York, whereas others walked around in “wooden clogs” as a kind of folk fashion, watched Kojak the bold police inspector, listened or sang to ABBA tunes, danced like in “Saturday night fever”. In December 1979 Pink Floyd released “The Wall” which became with 23 million sales the top seller of all 70s productions (Champ Hamish p.120). Some of these artists we can still enjoy jumping up and down on stages across the world or being honoured with a Nobel prize in literature like Bruce Springsteen.
The wild 70s are remembered for the sexual revolution, the philosophy of love and peace as well as the continued spirit of the civil rights movements (Particia Massó, 2010). The sexual revolution spurred women’s liberation just as additional exploitation by thriving borderless consumption industry. Sex sells and it sold well. The cinema and print industry cashed in on the new trends and the spreading the new trends. Social relationships became much more unstable, divorce rates increased sharply in the 70s. In response, “surviving the 70s” (DeMott, 1971) a kind of survival guide tried to give advice of how to stem the tide, largely unsuccess for some decades.
Societies continued to explore new forms of life, while some niches of conservative life styles started to shield themselves from these outrageous trends. Vasarely imitating tapestry and design invited new forms of facing your own walls. Where to go on from this liberalisation? More equal rights for all, was a claim, but it took several additional decades to achieve some of the claims. Intersectionality, viewing for example violence as an across gender, social class and ethnicity as an overall mankind issue, became a claim much later only. “All in all, it was just bricks in the wall”, a huge wall it still is. We haven’t climbed it yet. 
80s
The colourful 80s. That could be a summary of the years from 1980 to 1989. Certainly in fashion and design a multitude of colours dominated the 80s. Mariel Marohn (2010, Ed.) published 20 years later a visual summary of the 80s. Often thought as less spectacular than other decades, the 80s had seen some defeats to start with. John Lennon shot dead in New York December 1980. The NASA space shuttle Challenger explodes 2 minutes after the launch in 1986. Nuclear accidents (after three mile island 1979, Tschernobyl 1986,or the finding of the Titanic demonstrated not only the “limits to growth” (1972), but reminded us of deadly consequences of technological ambitions wanting to move too fast in time. Ghettoblaster, Walkman, first cell phones, facilitated a more mobile life style to more people. Overcoming the oil crises of the 70s, mobility roared ahead again. Cars, bikes, planes, CDs, windsurfing and aerobics become part of the lifestyle in these years.
Mass culture in music reached all levels of society. Music was no longer perceived as a protest movement, but a normal part of the freedom of expression. Fusion of music and dance, but also music and street art like in hip-hop music and graffiti art become part of day-to-day experiences of commuters. In the anthology of poems of the 80s we find on page 141 “Commuters” by Edward Hirsch 1983 who singles out the commuting practice as the way of life, he does not want to identify with. “Malgré lui”, in spite of himself, he finds himself in cars, trains travelling distances every day. More, faster and with more colours, time moved on. The fall of the Berlin wall 1989 was thought of as a “Zeitenwende” already. Royalty in the press with the marriage of Diana & Charles, was replaced by Madonna as the Queen of Pop and Michael Jackson as the King of Pop. The digital age entered into a new era with the Apple Macintosh desktop computer with an accessible visual interface to computing. Reaganomics and Thatcherism pushed for a revival of liberal market economies ploughing the fields for digital multinationals (GAFAM) to thrive ever since. These lasting technological changes define this period as colourful, grabbing all our senses and attention. Want to breathe a bit of the air of the 80s – visit MAD Paris. 
Photo
Photography has captured our imagination for years already.
It is now a daily activity of many people to “capture their experience”, if not even their existence in some photographed way. Susan Sontag (1977) coined the phrase that photography “feels like knowledge – and, therefore, like power”. You are in a relation to the world. Taking the photograph in my view is the Mephistopheles moment. You are in control of the object taken by the camera. Arranging the scenery, waiting for the perfect moment, expression, light or colours is like mastering a situation, an atmosphere, an emotion. Photographs have the power to work as a document. Editing has become easy and pervasive with digital tools. However, it was always present in the traditional technical parts of shooting and developing subsequently in the dark room.
“to be taken” on a photograph is more like the Faustian moment of realising that you are manipulated, or at risk of being made use of, for some purpose, unknown to you at that moment.
Beware, a photograph is always just an image of an image. The photographer is the intermediate person using a specific technology to transform his perception or vision of (her/his) reality into another image of it, creating some form of virtual reality.
In addition to this twofold transformation, the third transformation is historically the technical development of the negative into the print (see below). Nowadays, this is the compression and editing into a specific format. Despite these transformations, a photograph is admitted in court cases as providing evidence of guilt or to identify an illicit act (excess of speed limit). Infringements on privacy are the rule rather than the exception. Who is that person sitting next to you, and at what time of the day?
I, personally, apply photographs often like note-taking for research to capture spontaneous ideas or associations, which await further interpretation or may serve (served) as inspiration.
Compared to photography, painting has been a more elite artistic practice for many years. Taking photographs has democratised the image-taking art forms. Instead of originals, many of us have collections of photos from museums around the world. We take “photos of photos” to reveal the world around us and reflect on values. The social construction of the world is directly visible through the process of taking, collecting and curating photographs. Construct your own world or the world will construct or deconstruct you instead.
Politicians (e.g. Angela Merkel), John F. Kennedy or historical figures, all had their defining moment condensed into one or several photographs, what have been famous paintings in art history before. Susan Sontag wrote 50 years ago: “… a photograph can be treated as a narrowly selective transparency”. The third transformation of developing and/editing, shown in the images below, explains what we might learn from this citation in a technical sense. Just as courts have to evaluate, whether a proof is admittable and contributing to finding the truth; viewing photographs is a balancing act between art and truth.
“Even when photographers are most concerned with mirroring reality, they are still haunted by tacit imperatives of taste and conscience.” (Sontag, p.6). Photographs document sequences of consumption. We should frame this as CO2 footprints in the 21st century. Restricting print to a few “best of” was and is necessary to reduce the dirty footprint of photography, particularly since photos have become a mass media as much as the preferred media of masses.
With photographs we certify our own certificates, for example in case of job applications or passports. We encounter “cosmopolitans accumulating photograph-trophies” in all instagram-able locations.
Taking photos is like a “friendly imitation of work” (p.9), you do something useful in documenting the images of a world in danger of being lost. We can give importance to otherwise forgotten realities, attach importance even immortality to something or someone of our choice. We make history through it or try to make it at least. “When we are afraid, we shoot. But when we are nostalgic, we take pictures.” (p.9) Sontag defines photographs as part of the repertoire of surrealism (p.77 ff), “to finding beautiful what other people found ugly or without interest and relevance …”). We are at risk to mistake photographs as reality and experience the original as “letdown” (p.147). The return to polaroid instant photography brings us back to a proclaimed authenticity of the orginal, unique moments, with supposed unfiltered not-edited images. The true moment of having had fun or joint experience without use of photoshop to add the missing member.
“I take photos, therefore I am”, has become the mantra of modern societies. We tend to ignore that we are taken on photos a million more times than we take some ourselves (video surveillance). It is a question of power in the end. Edit yourself or you become edited.

Linguistics
The urge to program human language originates for some in the quest for better explanation or understanding, for others in the improvement of communication. Both approaches have witnessed rapid evolution in recent years. Based on linguistics, psycholinguistics, sociolinguistics or neuroscientific advances, the potential of knowledge creation and communication has risen due to computational models and applications to linguistics. ChatGPT3 and Neuroflash allow us to play around with the commonly available AI-applications. Construction of a linguistically informed Glossary of political and social ideas is a specific application case. In addition to the subject/object list we may add predicates or verbs to link subjects and objects. For this purpose, we construct a basic alphabetical list below which draws mainly on action verbs and is embedded in the socio-cultural environment of the sciences in general. A categorised list of verbs, like the one from Purdue University, is helpful to draw on several relatively distinct fields. With perspective on labour market or societal relevance the list focuses on verbs related to skill sets: administrative/managerial; communication; creative, information/data; caring/helping; efficiency; research; teaching/learning; technical. The categories are not mutually exclusive and may well be supplemented by additional categories like relational skills and transformational skills. Computational psycholinguistics (Crocker, 2006 pdf-file) differentiate the “principle of incremental comprehension” (add one word at a time) from the “concentric theory of complexity” (start from complexity to specificity or vice-versa) and the “deductive sentence processor”. ChatGPT is built on the incremental approach, supposed to be the fastest and probably a more reliable computational approach. We could just attempt to use the other approaches in the simple ABC glossary of subjects, objects and predicates to test for the possibility to build no-nonsense short sentences using random choices as starting points. The Oxford handbook of psycholinguistics highlights in the final chapter the theoretical alternative of connectionism (p.811). Symbolic computation construes cognition as mental states that are symbolically represented. The sequence of operations then runs from one representation to the next one. However, the connectionist model operates more like a neural network and proceeds with the parallel processing of notions, relations or patterns. A list of predicates or verbs might do the trick: Chose a subject, chose a predicate and an object to start playing around: Subjects: action balance corruption democracy enterprise freedom god health imagination joy knowledge law memory nature optimism policy question repairing society time union value war xeno yinyang zero.
Predicates: applies broadens creates directs establishes forms generates helps induces jeopardises keeps likes moderates needs opposes prioritises qualifies represents strengthens tests uses varies weighs x-outs yields zigzags.
Objects: freedom god health imagination joy knowledge law memory nature optimism policy question repairing society time union value war xeno yinyang zero action balance corruption democracy enterprise.
Writing
“Are you writing or what?”
New research on the fabrication of writing allows to debunk some of the received ideas about writers as living and drafting in a solitary space. However, the facts frequently show something different. In the journal of the BnF (images 2022), (Chroniques des la BnF Nr. 95 p.9 pdf-file) the BnF makes transparent the creative cosmos of Marcel Proust (Exhibition closed). From correspondence and other influential images, we learn about the “fabrique de l’oeuvre”. Far from writing his books from front to end in a linear fashion, Proust drafts “isolated sequences which he mounts, demounts and regroups sometimes even years later. These clippings of text are arranged by him like a patchwork, a collage rather than following a linear progression. Just peeping into the writer’s studio, drafting style and “paperoles” is fascinating. What a mess, some would say. What a huge imaginative space he has been living in, despite being reported to draft most of his work while actually being in his bed (Lire Magazine 12-2022). Beds are not always for sleeping, only. Today’s start-up enterprises frequently start from home, a century ago Proust demonstrated a lot can result from a very tiny physical space, but an enormous space in mind. 
Syntax
Syntax is just one of the categories of linguistics. Carl Lee Baker (1989) wrote a whole book 500 pages on just English syntax, can you imagine. I like his modesty in the introduction stating that English syntax is just a subfield of linguistics (p.12). Other languages have different structures, some might be very different from our ways to communicate even. The ways how animals or plants communicate is an exciting subfield of linguistics, psychology and biology (Carrie Fidgor, Pieces of Mind). The SPO structure of sentences is only one simple way of constructing sentences. Syntax is much more complex. The sociological aspect of linguistics and syntax lies in the “acceptability judgements”, which are present once we establish rules and sort phrases into correct or incorrect sentence structures. Norms and standardisation as well as authority to decide on correctness becomes an issue. Countries used to many dialects or multilingual populations are confronted with these issues on a daily basis. Linguistics as basis of communication is continuously present even in the mental structure. Bilingualism, tri-lingualism and their effects on minds, competences, behaviour, culture and societies are own thriving research fields. Building a sentence or a phrase, following Baker, is built around a head and their complements. Such minimal phrases are comparable to what we coin in a simplified manner the subject-predicate-object structure of a sentence. The definition of the nucleus of the structure of a sentence is also about conventions and acceptability. Staccato speech and rap-music are examples of forms of speech, which are often considered beyond the normal. Computer voices are becoming more normal as we are faced with chat bots all around us now. The image below reflects the simplified “representation of syntactic structure” (p.48 The Cambridge grammar of the English language 2002 review here). To play around with “Clause”, let us analyse the clause: I bought a shirt; I wonder what I bought. You know what I mean Klaus, it is a clause, or is it Dady gone gaga = DADA? 
Hypertext
Linking information, explanation and entertainment is the power of the world wide web. The tool used for this is the hypertext format of texts and media in general. Wittgenstein was already dissatisfied not to be able to show the steps of his thinking more explicitly. In the “Tractatus logico- philisophicus (Link to pdf-file de/engl” he uses the a cube (5.5423) to explain that we see to different facts depending on our point of departure of our vision. Try it with the logo of www.schoemann.org you should realize how our vision swops from one way of viewing the cube to another. The white corner is once in the front of the cube and appears to be in the back, when you move your vision further up. In general this leads us to be careful with the choice of our point of departure, not only for our vision. Context, some say background, is important to determine starting points. Adding the hypertext markup language to a document, like in a blog entry, allows readers (+algorithms) to see the cognitive structure surrounding a text as well. Potentially as a reader you enter into a multidimensional space with each blog entry. Any encyclopedia, glossary or index has an apparent alphabetical order to entries, but the links between the multiple entries remain hidden at first sight. With use of hypertext this has changed and each entry is turned into a 3-dimensional space, for example. Additionally, all entries have different numbers of links to other entries including dead-end entries. With the structure of links it is interesting to learn about the self-referencing just as much as about the disciplinary locus of a text, chapters, a book or a library. This helps to still see the forest despite all those trees in front of us ,or we see the geological structure of the mountain while in the middle of the forest. Happy travelling in our new knowledge space!
