In many fundamental respects it is similar to our senses of sight or hearing, to our body’s ability to metabolize, or to our abilities to walk or use our hands. Since reason is closely connected to our biological senses I start with the description of their limitations. I proceed to the discussion of some fundamental conceptual structures of reason, which may be deeply flawed in the face of reality as it is in itself, such as the concept of possibility, of time and of the beginning of all. I discuss shortly also the status of logic, scientific theories and language because of their close kinship to reason. Key words Reason, biology, spirituality, possibility, time Michal Kutáš
