I think it was while rehearsing a translation of _Les Fourberies de Scapin_ in Dublin, and noticing how passionless it all was, that I saw what should have been plain from the first line I had written, that tragedy must always be a drowning and breaking of the dykes that separate man from man, and that it is upon these dykes comedy keeps house. But I was not certain of the site (one always doubts when one knows no testimony but one's own); till somebody told me of a certain letter of Congreve's. He describes the external and superficial expressions of 'humour' on which farce is founded and then defines 'humour' itself, the foundation of comedy as a 'singular and unavoidable way of doing anything peculiar to one man only, by which his speech and actions are distinguished from all other men,' and adds to it that 'passions are too powerful in the sex to let humour have its course,' or as I would rather put it, that you can find but little of what we call character in unspoiled youth, whatever be the sex, for as he indeed shows in another sentence, it grows with time like the ash of a burning stick, and strengthens towards middle life till there is little else at seventy years. Since then I have discovered an antagonism between all the old art and our new art of comedy and understand why I hated at nineteen years Thackeray's novels and the new French painting. A big picture of cocottes sitting at little tables outside a cafe, by some follower of Manet's, was exhibited at the Royal Hibernian Academy while I was a student at a life class there, and I was miserable for days. I found no desirable place, no man I could have wished to be, no woman I could have loved, no Golden Age, no lure for secret hope, no adventure with myself for theme out of that endless tale I told myself all day long. Years after I saw the _Olympia_ of Manet at the Luxembourg and watched it without hostility indeed, but as I might some incomparable talker whose precision of gesture gave me pleasure, though I did not understand his language. I returned to it again and again at intervals of years, saying to myself, 'some day I will understand'; and yet, it was not until Sir Hugh Lane brought the _Eva Gonzales_ to Dublin, and I had said to myself, 'How perfectly that woman is realised as distinct from all other women that have lived or shall live' that I understood I was carrying on in my own mind that quarrel between a tragedian and a comedian which the Devil on Two Sticks in Le Sage showed to the young man who had climbed through the window.
