2. Consciousness in Sleeping and Waking States

But we enter a realm here where the following must always be kept in mind: The sun has to make a certain period of hours into daytime, and another period into night. But human beings are in a position to vary things and upset routines, like the coupon clipper who sleeps even though he isn't tired, voluntarily turning his attention inward, enjoying himself, really enjoying his body, or like a student cramming for examinations who, to some extent, overcomes his need for normal sleep. Many students sleep very little before examinations. But this brings up the big questions we will be concerning ourselves with, questions about necessity in outer nature, questions about the frequently discussed subject of chance, both in nature and in human life, questions about providence that apply to the entire universe.
