I have seen here [in London] a play on Faust, the most diabolic thing imaginable. The Mephistopheles is a masterpiece of caricature and intelligence.… - Eugène Delacroix

Of late, men seem to have been possessed by an incomprehensible impulse to strip themselves of everything with which nature has endowed them in order to make them superior to the beasts of burden. A philosopher is a gentleman who sits down four times a day to the best meals he can possibly obtain, and who considers that virtue, glory and noble sentiments should be indulged in only when they do not interfere with those four indispensable functions and all the rest of his little personal comforts. At this rate, a mule is a better philosopher by far, because in addition to all this he puts up with blows and hardship without complaint.

Moralists and philosophers (I mean true philosophers like Marcus Aurelius and Jesus Christ) never talked politics, they considered their subject only from the human standpoint. Equal rights and other such vain imaginings were not their concern; all that they enjoined upon mankind was resignation to fate...to the constant need to submit to the harsh decrees of nature- a need which no one can deny and no philanthropist can overcome. They asked nothing more of the sage than that he conform to the laws of nature and play his part in his appointed place amidst a general harmony. Illness, death, poverty, spiritual suffering, these are with us always and will torment us under any form of government; democracy or monarchy, it makes no odds. (20 February 1847)

A mere cast taken from nature will always be more real than the best copy a man can produce, for can anyone conceive that an artist’s hand is not guided by his mind…his strange task will not be tinged with the colour of his spirit?...For the word realism to have any meaning all men would need to be of the same mind and to conceive things in the same way. For what is the supreme purpose of every form of art if it be not the effect? (22 February 1860)
