If the human organism is fascinating, the environment which accompanies it is equally so – and not merely as a collection of particular things and events. Chemistry, biology, geology, and astronomy, are special fascinations with the details of our environment, but metaphysics is fascination with the whole story.

I find it almost impossible to imagine a sensitive human being bereft of metaphysical wonder, a person who does not have that marvelous urge to ask a question that cannot quite be formulated. But the question almost always implies a search for something basic to everything, for an underlying unity which our ordinary thinking and feeling do not grasp. Thought and sensation are analytical and selective, and thus present the world as no more than a multiplicity of things and events. Man has, however, a "metaphysical instinct" which apparent multiplicity does not satisfy.

Man is intuitively certain that the entire multitude of things and events is "on" or "in". Something as reflections are on a mirror,
