What do you think an artist is? An imbecile who only has eyes if he is a painter, or ears if he's a musician, or a lyre at every level of his heart if he's a poet, or even, if he's a boxer, just his muscle? On the contrary, he is at the same time a political being, constantly alive to heartrending, fiery or happy events to which he responds in every way. How could it be possible to feel no interest in other people and by virtue of an ivory indifference to detach yourself from the life which they so copiously bring you? No, painting is not done to decorate apartments. It's an instrument of war for attack and defense against the enemy.
