“Everything we do is for the purpose of altering consciousness. We form friendships so that we can feel love and avoid loneliness. We eat specific foods to enjoy their fleeting presence on our tongues. We read for the pleasure of thinking another person’s thoughts. Every waking moment—and even in our dreams—we struggle to direct the flow of sensation, emotion, and cognition toward states of consciousness that we value.”

Sam Harris, Waking Up (Page 186)
