Context: Orwell can only be understood as an essentially quixotic man. … He defended, passionately and as a matter of principle, unpopular causes. Often without regard to reason he would strike out against anything which offended his conceptions of right, justice and decency, yet, as many who crossed lances with him had reason to know, he could be a very chivalrous opponent, impelled by a sense of fair play that would lead to public recantation of accusations he had eventually decided were unfair. In his own way he was a man of the left, but he attacked its holy images as fervently as he did those of the right. And however much he might on occasion find himself in uneasy and temporary alliance with others, he was — in the end — as much a man in isolation as Don Quixote. His was the isolation of every man who seeks the truth diligently, no matter how unpleasant its implications may be to others or even to himself.

“Artists who seek perfection in everything are those who cannot attain it in anything.”
Les artistes qui cherchent la perfection en tout sont ceux qui ne peuvent l'atteindre en aucune partie.
