Quality and quantity or queer and query could have made valuable entries here as well. Common to all is the underlying process of questions. Questions put to oneself, to others, society or supra natural or supra national instances. Can quantity turn into quality? Is a queer perspective a new one? Is a query in a programming language the beginning of each algorithm? Questioning is a child’s “natural” approach to understanding the world. This does not stop soon after childhood, but it is occupying, if not haunting, us until the end of our life. When is this exactly happening – the end thing? Are we free to chose this? Just try to answer one of these questions and you’ll find out how one question leads to the next. We are all the same in this behaviour. However, we all find different stopping rules to the query algorithm. Religion is a fast shortcut to stop further questions. Sciences are the never, ever, ending type of questioning. Mathematics solved part of the problem. For a lot of series we are able to calculated the limit value towards which the series evolves circumventing the lack of a stopping rule. Fundamental human rights are such a far-reaching stopping rule. Just like after the French revolution, the question was, how to quickly spread the message of human rights. Didactic and paedagogics evolved in parallel. From “cogito ergo sum” to “rogatio ergo sum”.
