"Early on, I learnt from the Russian intelligentsia that the only meaning of life lies in conscious participation in the making of history. The more I think of that, the more deeply true it seems to be. It follows that one must range oneself actively against everything that diminishes man, and involve oneself in all struggles which tend to liberate and enlarge him. This categorical imperative is by no way lessened by the fact that such an involvement is inevitably soiled by error: it is a worse error merely to live for oneself, caught within traditions which are soiled by inhumanity."
