this selection from Ayn Rand, which he thinks seems to indicate a lack of human emotion:
Just as the pleasure-pain mechanism of man’s body is an automatic indicator of his body’s welfare or injury, a barometer of its basic alternative, life or death—so the emotional mechanism of man’s consciousness is geared to perform the same function, as a barometer that registers the same alternative by means of two basic emotions: joy or suffering. Emotions are the automatic results of man’s value judgments integrated by his subconscious; emotions are estimates of that which furthers man’s values or threatens them, that which is for him or against him—lightning calculators giving him the sum of his profit or loss.
But while the standard of value operating the physical pleasure-pain mechanism of man’s body is automatic and innate, determined by the nature of his body—the standard of value operating his emotional mechanism, is not. Since man has no automatic knowledge, he can have no automatic values; since he has no innate ideas, he can have no innate value judgments.
Man is born with an emotional mechanism, just as he is born with a cognitive mechanism; but, at birth,both are “tabula rasa.” It is man’s cognitive faculty, his mind, that determines the content of both. Man’s emotional mechanism is like an electronic computer, which his mind has to program—and the programming consists of the values his mind chooses.
But since the work of man’s mind is not automatic, his values, like all his premises, are the product either of his thinking or of his evasions: man chooses his values by a conscious process of thought—or accepts them by default, by subconscious associations, on faith, on someone’s authority, by some form of social osmosis or blind imitation. Emotions are produced by man’s premises, held consciously or subconsciously, explicitly or implicitly.
