Consciousness is the quality or state of being aware. To be conscious in the philosophical sense means to have mental processes that are self-directed  and which provide a locus of subjective experience. Animals are alleged to possess a form of consciousness  although this is not necessarily to be equated with the Christian notion of having moral worth or an immortal soul.
