Think of it : zillions and zillions of organisms running around, each under the hypnotic spell of a single truth, all these truths identical, and all logically incompatible with one another : 'My hereditary material is the most important material on earth; its survival justifies your frustration, pain, even death'. And you are one of those organisms, living your life in the thrall of a logical absurdity.
