And so too it is a very important fact that the truth or falsity of non-logical propositions cannot be recognized from the propositions alone. It also becomes clear now why logic was called the theory offorms and of inference. 6.123 Clearly the laws of logic cannot in their turn be subject tolaws of logic. 6.1261 In logic process and result are equivalent. 6.13 Logic is not a body of doctrine, but a mirror-image of the world.
Logic is transcendental.
6.2 Mathematics is a logical method. The propositions of mathematicsare equations, and therefore pseudo-propositions. 6.21 A proposition of mathematics does not express a thought. The logic of the world, which is shown in tautologies by the propositions of logic, is shown in equations by mathematics. 6.234 Mathematics is a method of logic.
