“Whenever man believes that life is meaningless, whenever he feels that value fulfillment is impossible, or indeed nonexistent, then he undermines his genetic heritage. He separates himself from life’s meaning. He feels vacant inside. … Any philosophy that promotes the idea that life is meaningless is biologically dangerous. It promotes feelings of despair that directly hamper genetic activity. Such philosophies are extremely disadvantageous creatively, since they dampen the emotional spirits and exuberance, and sense of play, from which creativity itself emerges.
“Such philosophies are also deadening on an intellectual basis, for they must, of necessity, close out man’s great curiosity about the subjective matters that are his main concern. If life has no meaning, then nothing else really makes any difference, and intellectual curiosity itself also ends up withering on the vine.
“The intellectual ideas of species, therefore, also have a great effect upon which genetic systems are triggered, and which ones are not.”
