Wittgenstein before breakfast IV

6 – The general form of truth-function is: [p, E, N(E)]. This is the general form of proposition.


6.1 – The propositions of logic are tautologies.

6.2 – Mathematics is a logical method. The propositions of mathematics are equations, and therefore pseudo-propositions.

6.3 – Logical research means the investigation of all regularity. And outside logic all is accident.

6.4 – All propositions are of equal value.

6.5 – For an answer which cannot be expressed the question too cannot be expressed. The riddle does not exist. If a question can be put at all, then it can also be answered.

From the Tractatus Logico-Philosophicus, statements 6.0-6.5 (link to Laventhol’s online edition).
