[Human behavior between instinct, feelings and responsibility].

The paper deals with the fundamental problem: How does the brain (in the way it is and the way it functions) influence human experience, behaviour and social interaction? Deriving from this question, there's the matter of how all this influences people as road users. After some epistemological considerations the following subjects are dealt with the article: the human perception and human "reality", the limits of human imagination, the basis of human learning, the complexity of processes within the brain, the reaction to changes and the ability to concentrate as well as McLean's theory of the triune brain. The subjects are complemented by aspects of biological and socio-cultural evolution of man, starting from evolutionary ethics going right up to the problem of responsibility.
