Anxiety is a primordial affect, always liable to reappear, through which the subject, in his/her relations to the Nebenmensch, questions his/her place in the world and his/her relationship with others. The quest for truth, which is an attempt to find an answer to these questions, is an always risky activity of thought which culminates in establishing beliefs. The first benefit of establishing these beliefs is to relieve anxiety. This is the aim of this thought process.
