Not only the entire ability to think rests on language... but language is also the crux of the misunderstanding of reason with itself.

Everything the human being heard from the beginning, saw with its eyes, looked upon and touched with its hands was a living word; for God was the word.

Self knowledge begins with the neighbor, the mirror, and just the same with true self-love; that goes from the mirror to the matter.

Nature is a book, a letter, a fairy tale (in the philosophical sense) or whatever you want to call it.

I look upon logical proofs the way a well-bred girl looks upon a love letter

Physics is nothing but the ABC's. Nature is an equation with an unknown, a Hebrew word which is written only with consonants to which reason has to add the dots.

Being, belief and reason are pure relations, which cannot be dealt with absolutely, and are not things but pure scholastic concepts, signs for understanding, not for worshipping, aids to awaken our attention, not to fetter it.
