For remember that in general we don't use language according to strict rules-- it hasn't been taught to us by means of strict rules, either. We, in our discussions on the other hand, constantly compare language with a calculus preceding to exact rules.

Just be indipendent of the external world, so you don't have to fear for what's in it.

If a person tells me he has been to the worst places I have no reason to judge him; but if he tells me it was his superior wisdom that enabled him to go there, then I know he is a fraud.

Sometimes, in doing philosophy, one just wants to utter an inarticulate sound.

If we were to imagine an orange on the blue side or green on the red side or violet on the yellow side, it would give us the same impression as a north wind coming from the southwest.

When philosophers use a word--"knowledge," "being," "object," "I," "proposition," "name"--and try to grasp the essence of the thing, one must always ask oneself: is the word ever actually used in this way in the language-game which is its original home?--What we do is to bring words back from their metaphysical to their everyday use.

If there were a verb meaning "to believe falsely," it would not have any significant first person, present indicative.
