Hatred is an affair of the heart; contempt that of the head.

Truth that is naked is the most beautiful, and the simpler its expression the deeper is the impression it makes.

The intellectual attainments of a man who thinks for himself resemble a fine painting, where the light and shade are correct, the tone sustained, the colour perfectly harmonised; it is true to life. On the other hand, the intellectual attainments of the mere man of learning are like a large palette, full of all sorts of colours, which at most are systematically arranged, but devoid of harmony, connection and meaning.

The greatest achievements of the human mind are generally received with distrust.

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.

In order to increase his pleasures, man has intentionally added to the number and pressure of his needs, which in their original state were not much more difficult to satisfy than those of the brute. Hence luxury in all its forms; delicate food, the use of tobacco and opium, spirituous liquors, fine clothes, and the thousand and one things that he considers necessary to his existence.

It is only at the first encounter that a face makes its full impression on us.
