The Blue and Brown Books Quotes

“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.”
― Ludwig Wittgenstein, The Blue and Brown Books

“Philosophy, as we use the word, is a fight against the fascination which forms of expression exert upon us.”
― Ludwig Wittgenstein, کتاب آبی

“Frege ridiculed the formalist conception of mathematics by saying that the formalists confused the unimportant thing, the sign, with the important, the meaning. Surely, one wishes to say, mathematics does not treat of dashes on a bit of paper. Frege’s idea could be expressed thus: the propositions of mathematics, if they were just complexes of dashes, would be dead and utterly uninteresting, whereas they obviously have a kind of life. And the same, of course, could be said of any proposition: Without a sense, or without the thought, a proposition would be an utterly dead and trivial thing. And further it seems clear that no adding of inorganic signs can make the proposition live. And the conclusion which one draws from this is that what must be added to the dead signs in order to make a live proposition is something immaterial, with properties different from all mere signs.
But if we had to name anything which is the life of the sign, we should have to say that it was its use.”

“The difficulty in philosophy is to say no more than we know”
