Definitions are rules for translating from one language into another.
The totality of propositions is language.
Philosophy aims at the logical clarification of thoughts.
Tautologies and contradictions lack sense.
All deductions are made a priori.
Simplex sigillum veri.
In a certain sense, we cannot make mistakes in logic.
The limits of my language mean the limits of my world.
We cannot think what we cannot think; so what we cannot think we cannot say either.
The philosophical self is not the human being, not the human body, or the human soul, with which psychology deals, but rather the metaphysical subject, the limit of the world—not a part of it.
It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all 'true' logical propositions.
El ruliad?
Logic is not a body of doctrine, but a mirror-image of the world. Logic is transcendental.
Mathematics is a logical method. The propositions of mathematics are equations, and therefore pseudo-propositions.
Mechanics is an attempt to construct according to a single plan all the true propositions that we need for the description of the world.
The world is independent of my will.
So too at death the world does not alter, but comes to an end.
Our life has no end in just the way in which our visual field has no limits.
The correct method in philosophy would really be the following: to say nothing except what can be said, i.e. propositions of natural science—i.e. something that has nothing to do with philosophy—and then, whenever someone else wanted to say something metaphysical, to demonstrate to him that he had failed to give a meaning to certain signs in his propositions. Although it would not be satisfying to the other person—he would not have the feeling that we were teaching him philosophy—this method would be the only strictly correct one.
