A man's knowledge may be said to be mature, in other words, when it has reached the most complete state of perfection to which he, as an individual, is capable of bringing it, when an exact correspondence is established between the whole of his abstract ideas and the things he has actually perceived for himself. His will mean that each of his abstract ideas rests, directly or indirectly, upon a basis of observation, which alone endows it with any real value; and also that he is able to place every observation he makes under the right abstract idea which belongs to it.
In our early youth we sit before the life that lies ahead of us like children sitting before the curtain in a theatre, in happy and tense anticipation of whatever is going to appear. Luckily we do not know what really will appear.
Man may have the most excellent judgment in all other matters, and yet go wrong in those which concern himself; because here the will comes in and deranges the intellect at once.

As the strata of the earth preserve in succession the living creatures of past epochs, so the shelves of libraries preserve in succession the errors of the past and their expositions, which like the former were very lively and made a great commotion in their own age but now stand petrified and stiff in a place where only the literary palaeontologist regards them.

As my own father was sick, and miserably tied to his invalid's chair, he would have been abandoned had not an old servant performed for him a so-called service of love. My mother gave parties while he was perishing in solitude, and amused herself while he was suffering bitter agonies
Scholars are those who have read in books, but thinkers, men of genius, world-enlighteners, and reformers of the human race are those who have read directly in the book of the world.
JedeTrennung gibt einenVorgeschmack desTodesund jedes Wiedersehen einenVorgeschmack der Auferstehung. Every parting is a foretaste of death, and every reunion a foretaste of resurrection.
there are very few who can think, but every man wants to have an opinion; and what remains but to take it ready-made from others, instead of forming opinions for himself?
I observed once to Goethe that when a friend is with us we do not think the same of him as when he is away. He replied, "Yes! because the absent friend is yourself, and he exists only in your head; whereas the friend who is present has an individuality of his own, and moves according to laws of his own, which cannot always be in accordance with those which you form for yourself.
