"If one could only fly over the Earth and show everybody, Chinese gardeners live side by side in old fashion. Next to them a capitalist germ cell which puts its feelers out into the country! See the factory chimney smoking! Ships come and go. And in the North, nomads and tribes of hunters who don’t know anything of a capitalist order even though they sell furs to entrepreneurs. A sharpened eye would be able to grasp this. All of this can be grasped and represented in pictures!"

“Science as a system of statements is always an object of discussion. Statements are to be compared with statements, and not with 'experience', or with 'the world', or with something else. All that meaningless doubling belongs to more or less subtle metaphysics and as such must be rejected. Every new statement is to be confronted with existing ones, already brought to a state of harmony between themselves. A statement will be considered correct if it can be joined to them.”

“The primordial forms of all sciences, taken back beyond the rise of writing, lie ultimately in the magic of prehistory. Just as modern man wants to indicate what consequences his actions will have, so also a man who grows up in the magical way of life seeks to find a ground for everything and to find consequences of his action. Magic as a more or less clearly formulated system of tenets shot through with emotional elements, can become independent only when magicians, acting as specialists, proclaim the consequences of certain customs, either esoterically,. e.g. at certain rituals, or exoterically as popular education. The magicians tell what cases are to count as 'equal', and when certain measures shall be used .”

“In the interest of scientific work, more and more formulations in the unified language of unified science are becoming increasingly precise. No term of unified science, however, is free from imprecision, since all terms are based on terms that are essential for protocol statements, whose imprecision must be immediately obvious to everyone.”

“The motivationless theory of goods can bridge the gulf between history and exact research by securing the important continuity of the research, being linked to both.”

“Quite a few political economists advocate the thesis that a Robinson Crusoe — or what amounts to the same thing, a controlled economy — calculates in terms of profits and losses.”

“Overcoming magic often takes the form of theology. From animals and ancestors the path leads to all kinds of spirits. The hypothesis of the little man alongside man, the “soul', and of the special being, 'God', more and more often seeks a parallel process 'behind' processes. Whereas in the magical age, empirically given facts were linked with each other on the basis of primitive theories without the introduction of uncontrollable elements, now their introduction becomes essential.”
