“It takes too much imagination to see the sorrows of people we take for happy. Their real battles take place, like those of the stars, in some realm of light imperceptible to the human eye. It is a feat of the mind to guess another's heart.”

The Snow Leopard (1978)
Context: The progress of the sciences toward theories of fundamental unity, cosmic symmetry (as in the unified field theory) — how do such theories differ, in the end, from that unity which Plato called “unspeakable” and “indiscribable,” the holistic knowledge shared by so many peoples of the earth, Christians included, before the advent of the industrial revolution made new barbarians of the peoples of the West? In the United States, before spiritualist foolishness at the end of the last century confused mysticism with “the occult” and tarnished both, William James wrote a master work of metaphysics; Emerson spoke of “the wise silence, the universal beauty, to which every part and particle is equally related, the eternal One . . .”; Melville referred to “that profound silence, that only voice of God”; Walt Whitman celebrated the most ancient secret, that no God could be found “more divine than yourself.” And then, almost everywhere, a clear and subtle illumination that lent magnificence to life and peace to death was overwhelmed in the hard glare of technology. Yet that light is always present, like the stars of noon. Man must perceive it if he is to transcend his fear of meaningless, for no amount of “progress” can take its place. We have outsmarted ourselves, like greedy monkeys, and now we are full of dread.
