Man was not present at his origin. Could not. Therefore, we are constantly trying to understand ourselves. Why did Cain kill Abel? Why did Herostratus burn the temple, and we cannot forget his act? We have been using fire since time immemorial, but we have not yet offered an explanation for this fact. People have been looking for answers to these questions for many centuries; we think that they will help to understand the actions of people, especially in extreme situations, as, for example, in the case of A. Breivik. This book makes an attempt, based on the philosophical concept of M. Heidegger, to explain why this is even possible and why the “moral law within us” does not always operate.
