In any question, as Heidegger pointed out, it is necessary to differ-asked(das Gefragte)-being-what is asked(das Befragte) being itself and something that has been asked and interrogated(das Erfragte)-the essence of being. A man finds his essence  in dependence of the things that cohere to the truth of being,and that means that he is ready to think the truth.
Axiology-a branch of philosophy which explored values. The problem is in the very determination of the definition of values and their qualification.
