Abstract

The paper offers an account of consciousness as a biological process. All its theoretical concepts are derived from the biological context and accurately defined in causal and functional terms. To cover the essence of what is commonly meant by the word ‘consciousness’, and to avoid confusion through a selective or theoretically biased interpretation of that word, the paper addresses the dimensions of awareness which the word denotes according to the dictionaries of the English language, viz., an awareness of the surrounding world, of the self, and of one's thoughts and feelings. These are examined at the primary levels at which they might exist also in nonhuman species.
