There are two aspects of man’s existence which are the special province and expression of his sense of life: love and art.I am referring here to romantic love, in the serious meaning of that term—as distinguished from the superficial infatuations of those whose sense of life is devoid of any consistent values, i.e., of any lasting emotions other than fear. Love is a response to values. It is with a person’s sense of life that one falls in love—with that essential sum, that fundamental stand or way of facing existence, which is the essence of a personality. One falls in love with the embodiment of the values that formed a person’s character, which are reflected in his widest goals or smallest gestures, which create the style of his soul—the individual style of a unique, unrepeatable, irreplaceable consciousness. It is one’s own sense of life that acts as the selector, and responds to what it recognizes as one’s own basic values in the person of another. It is not a matter of professed convictions (though these are not irrelevant); it is a matter of much more profound, conscious and subconscious harmony.Many errors and tragic disillusionments are possible in this process of emotional recognition, since a sense of life, by itself, is not a reliable cognitive guide. And if there are degrees of evil, then one of the most evil consequences of mysticism—in terms of human suffering—is the belief that love is a matter of “the heart,” not the mind, that love is an emotion independent of reason, that love is blind and impervious to the power of philosophy. Love is the expression of philosophy—of a subconscious philosophical sum—and, perhaps, no other aspect of human existence needs the conscious power of philosophy quite so desperately. When that power is called upon to verify and support an emotional appraisal, when love is a conscious integration of reason and emotion, of mind and values, then—and only then—it is the greatest reward of man’s life.
Evolution endowed us with intuition only for those aspects of physics that had survival value for our distant ancestors, such as the parabolic orbits of flying rocks (explaining our penchant for baseball). A cavewoman thinking too hard about what matter is ultimately made of might fail to notice the tiger sneaking up behind and get cleaned right out of the gene pool. Darwin’s theory thus makes the testable prediction that whenever we use technology to glimpse reality beyond the human scale, our evolved intuition should break down. We’ve repeatedly tested this prediction, and the results overwhelmingly support Darwin. At high speeds, Einstein realized that time slows down, and curmudgeons on the Swedish Nobel committee found this so weird that they refused to give him the Nobel Prize for his relativity theory. At low temperatures, liquid helium can flow upward. At high temperatures, colliding particles change identity; to me, an electron colliding with a positron and turning into a Z-boson feels about as intuitive as two colliding cars turning into a cruise ship. On microscopic scales, particles schizophrenically appear in two places at once, leading to the quantum conundrums mentioned above. On astronomically large scales… weirdness strikes again: if you intuitively understand all aspects of black holes [then you] should immediately put down this book and publish your findings before someone scoops you on the Nobel Prize for quantum gravity… [also,] the leading theory for what happened [in the early universe] suggests that space isn’t merely really really big, but actually infinite, containing infinitely many exact copies of you, and even more near-copies living out every possible variant of your life in two different types of parallel universes.
