To gain anything we have longed for is only to discover how vain and empty it is; and even though we are always living in expectation of better things, at the same time we often repent and long to have the past back again.
Talent is able to achieve what is beyond other people's capacity to achieve, yet not what is beyond their capacity of apprehension; therefore it at once finds its appreciators. The achievement of genius, on the other hand, transcends not only others' capacity of achievement, but also their capacity of apprehension; therefore they do not become immediately aware of it. Talent is like the marksman who hits a target which others cannot reach; genius is like the marksman who hits a target, as far as which others cannot even see.
There are three stages in the revelation of truth. The first is to be ridiculed, the second is to be resisted and the third is to be considered self-evident.

Many books serve merely to show how many ways there are of being wrong, and how far astray you yourself would go if you followed their guidance. You should read only when your own thoughts dry up.
If the lives of men were relieved of all need, hardship and adversity; if everything they took in hand were successful, they would be so swollen with arrogance that, though they might not burst, they would present the spectacle of unbridled folly-nay, they would go mad. And I may say, further, that a certain amount of care or pain or trouble is necessary for every man at all times. A ship without ballast is unstable and will not go straight.
The discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice.
