Aforismi in lingua originale - Autobiografia.

In truth, the story of what was called my Optimism was rather odd. When I had been for some time in these, the darkest depths of the contemporary pessimism, I had a strong inward impulse to revolt; to dislodge this incubus or throw off this nightmare. But as I was still thinking the thing out by myself, with little help from philosophy and no real help from religion, I invented a rudimentary and makeshift mystical theory of my own. It was substantially this; that even mere existence, reduced to its most primary limits, was extraordinary enough to be exciting. Anything was magnificent as compared with nothing. Even if the very daylight were a dream, it was a day-dream; it was not a nightmare. The mere fact that one could wave one's arms and legs about (or those dubious external objects in the landscape which were called one's arms and legs) showed that it had not the mere paralysis of a nightmare. Or if it was a nightmare, it was an enjoyable nightmare. In fact, I had wandered to a position not very far from the phrase of my Puritan grandfather, when he said that he would thank God for his creation if he were a lost soul. I hung on to the remains of religion by one thin thread of thanks. I thanked whatever gods might be, not like Swinburne, because no life lived for ever, but because any life lived at all; not, like Henley for my unconquerable soul (for I have never been so optimistic about my own soul as all that) but for my own soul and my own body, even if they could be conquered. This way of looking at things, with a sort of mystical minimum of gratitude, was of course, to some extent assisted by those few of the fashionable writers who were not pessimists; especially by Walt Whitman, by Browning and by Stevenson; Browning's "God must be glad one loves his world so much", or Stevenson's "belief in the ultimate decency of things". But I do not think it is too much to say that I took it in a way of my own; even if it was a way I could not see clearly or make very clear. What I meant, whether or no I managed to say it, was this; that no man knows how much he is an optimist, even when he calls himself a pessimist, because he has not really measured the depths of his debt to whatever created him and enabled him to call himself anything. At the back of our brains, so to speak, there was a forgotten blaze or burst of astonishment at our own existence. The object of the artistic and spiritual life was to dig for this submerged sunrise of wonder; so that a man sitting in a chair might suddenly understand that he was actually alive, and be happy.
