All knowledge which ends in words will die as quickly as it came to life, with the exception of the written word: which is its mechanical part.

To use the same words is not a sufficient guarantee of understanding; one must use the same words for the same genus of inward experience; ultimately one must have one's experiences in common.

Words are but symbols for the relations of things to one another and to us; nowhere do they touch upon absolute truth.

Think before you speak, your words could hurt someone's feeling more than you intended it to.

My dear Tiberius, you must not give way to youthful emotion or take it to heart if anyone speaks ill of me; let us be satisfied if we can make people stop short at unkind words.

I think the words you stop yourself from saying are the ones that will haunt you the longest.
