ABSTRACT
Consciousness is that mental state in which we are aware of our existence and sensations, and the condition at the moment of our thoughts, feelings, and actions. Consciousness means awareness; we are not aware of things of which we are not conscious. When there is only one response possible to a sensation, we get automatic (reflex) action, and consciousness, if aroused at all, is slight. The greater the complexity of the nervous system, the more numerous the possible responses to a sensation, the greater will be the hesitation and choice, and the more intense the consciousness.
