“You are no doubt aware that the Almighty, desiring to lead us to perfection and to improve our state of society, has revealed to us laws which are to regulate our actions. These laws, however, presuppose an advanced state of intellectual culture. We must first form a conception of the Existence of the Creator according to our capabilities; that is, we must have a knowledge of Metaphysics. But this discipline can only be approached after the study of Physics: for the science of Physics borders on Metaphysics, and must even precede it in the course of our studies, as is clear to all who are familiar with these questions.”

is nothing but another and most convenient fairy-tale. Primitive tribes has more detailed classifications of animals and plant than contemporary scientific zoology and botany, they know remedies whose effectiveness astounds physicians (while the pharmaceutical industry already smells here a new source of income), they have means of influencing their fellow men which science for a long time regarded as non-existent (voodoo), they solve difficult problems in ways which are still not quite understood (building of the pyramids; Polynesian travels), there existed a highly developed and internationally known astronomy in the old Stone Age, this astronomy was factually adequate as well as emotionally satisfying, it solved both physical and social problems (one cannot say the same about modern astronomy) and it was tested in very simple and ingenious ways (stone observatories in England and in the South Pacific; astronomical schools in Polynesia - for a more details treatment an references concerning all these assertions cf. my Einfuhrung in die Naturphilosophie). There was the domestication of animals, the invention of rotating agriculture, new types of plants were bred and kept pure by careful avoidance of cross fertilization, we have chemical inventions, we have a most amazing art that can compare with the best achievement of the present. True, there were no collective excursions to the moon, but single individuals, disregarding great dangers to their soul and their sanity, rose from sphere to sphere to sphere until they finally faced God himself in all His splendor while others changed into animals and back into humans again. At all times man approached his surroundings with wide open senses and a fertile intelligence, at all times he made incredible discoveries, at all times we can learn from his ideas.

Day of Affirmation Address (1966)
Context: The help and the leadership of South Africa or of the United States cannot be accepted if we, within our own country or in our relationships with others, deny individual integrity, human dignity, and the common humanity of man. If we would lead outside our borders, if we would help those who need our assistance, if we would meet our responsibilities to mankind, we must first, all of us, demolish the borders which history has erected between men within our own nations — barriers of race and religion, social class and ignorance.
Our answer is the world's hope; it is to rely on youth. The cruelties and the obstacles of this swiftly changing planet will not yield to obsolete dogmas and outworn slogans. It cannot be moved by those who cling to a present which is already dying, who prefer the illusion of security to the excitement and danger which comes with even the most peaceful progress. This world demands the qualities of youth: not a time of life but a state of mind, a temper of the will, a quality of the imagination, a predominance of courage over timidity, of the appetite for adventure over the love of ease.
