Abstract
The paper centers on philosophy's major trends and trials at the turn of the XXt h and XXIs t century, its leading idea is based on several basic assumptions which can be summarized as follows: 1) the title is a query after XXt h-century philosophy's main achievements and their usefulness in the XXIs t ; 2) speaking about philosophy's achievements, the author particularly means its critical role in condemning and de-mystifying evil, dispelling illusion and myth, and disclosing untruth; 3) the answer to the titular question is based on the entire paper's main assumption that there are three main problems of XXt h-century thought which - as a heritage - will be carrying over into the XXIs t. These problems are the problem of being (Sein), the problem of reason, and the problem of humanity (man). In connection with these problems the author formulates his main thesis that the twentieth century philosophy is characterized by three features which are the following: (a) anti-metaphysical disposition, (b) anti-rationalism, and (c) anti-humanism.
