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

If only I was as eloquent as Demosthenes, I would have to do no more than repeat a single word three times.

When I rest my feet my mind also ceases to function.

The farther reason looks the greater is the haze in which it loses itself.

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

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.

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.
