Among the different exercises of philosophical practice, there is one that can be practiced alone: the self-consultation. It is a form of self-questioning, in written form. To do so orally would be lacking in rigor and too approximative. The principle is the same as in a “normal” consultation, except that the two interlocutors are the same person. Whoever practices the exercise must in turn play the role of the "subject" and that of the "philosopher", a bit like playing chess with oneself. The work begins with an interrogation which interests or worries the "subject", and the "philosopher" will ask a series of questions allowing to deepen the problem and to consider new hypotheses, with an often surprising result. The main problem is to ask effective questions and avoid complacency with oneself, which requires some training. The session to which we invite you will be an introduction to this practice, or an additional training for those who are already initiated, through a live demonstration.
