Describing and explaining consciousness.

Abstract

Consciousness is a property of advanced brains and as such a biological feature. Explaining biological features is somewhat different from explaining physical phenomena; in the former case, the key is to first define its functional role (the reason why it was selected) and then to outline the evolutionary trajectory leading to its presence. In the case of consciousness, there are reasonable models for both. Further research is required to substantiate these models, but they offer, arguably, the best explanatory framework.
