The paper deals with the concept of “human nature” and focuses on the question of what is the place of this concept, not only in the history of philosophy but also in the contemporary philosophical and scientific thought. The author aims to describe the concept of human nature by a historical overview of philosophical attempts to characterize it. The only way to construct philosophy for life, for future, for continuation of human history is a philosophical and scientific investigation. However, a strange thing is happening in modern philosophy: many philosophers do not seem to believe that there is such a thing as human nature. What makes this strange is that not only does the new attitude run counter to much of the history of philosophy but – despite loud claims to the contrary – it also goes against the findings of modern science.
