The state of being conscious; knowledge of one's own existence, condition, sensations, mental operations, acts, etc.
Immediate knowledge or perception of the presence of any object, state, or sensation. See the Note under Attention.
A synonym for awareness; also the capacity for an organism to respond to or at least to note intra- and extrasomatic events and objects. C. S. Peirce suggested that consciousness is a fabric of signs, because of the representations inherent in thought (we think in language as well as images).
