It is the illusion of knowledge.“ — Stephen Hawking „Poverty, ignorance, illness and other problems of that kind are not metaphysical emergencies. By the metaphysical nature of man and of existence, man has to maintain his life by his own effort; the values he needs—such as wealth or knowledge—are not given to him automatically, as a gift of nature, but have to be discovered and achieved by his own thinking and work.“ — Ayn Rand
