It was at Naples, in the winter of 1907, that I first saw the Philosopher of Aesthetic. Benedetto Croce, although born in the Abruzzi, Province of Aquila (1866), is essentially a Neapolitan, and rarely remains long absent from the city, on the shore of that magical sea, where once Ulysses sailed, and where sometimes yet (near Amalfi) we may hear the Syrens sing their song. But more wonderful than the song of any Syren seems to me the Theory of Aesthetic as the Science of Expression, and that is why I have overcome the obstacles that stood between me and the giving of this theory, which in my belief is the truth, to the English-speaking world. No one could have been further removed than myself, as I turned over at Naples the pages of _La Critica_, from any idea that I was nearing the solution of the problem of Art. All my youth it had haunted me. As an undergraduate at Oxford I had caught the exquisite cadence of Walter Pater's speech, as it came from his very lips, or rose like the perfume of some exotic flower from the ribbed pages of the _Renaissance_. Seeming to solve the riddle of the Sphinx, he solved it not--only delighted with pure pleasure of poetry and of subtle thought as he led one along the pathways of his Enchanted Garden, where I shall always love to tread. Oscar Wilde, too, I had often heard at his best, the most brilliant talker of our time, his wit flashing in the spring sunlight of Oxford luncheon-parties as now in his beautiful writings, like the jewelled rapier of Mercutio. But his works, too, will be searched in vain by the seeker after definite aesthetic truth. With A.C. Swinburne I had sat and watched the lava that yet flowed from those lips that were kissed in youth by all the Muses. Neither from him nor from J.M. Whistler's brilliant aphorisms on art could be gathered anything more than the exquisite pleasure of the moment: the _monochronos haedonae_. Of the great pedagogues, I had known, but never sat at the feet of Jowett, whom I found far less inspiring than any of the great men above mentioned. Among the dead, I had studied Herbert Spencer and Matthew Arnold, Schopenhauer, Nietzsche and Guyau: I had conversed with that living Neo-Latin, Anatole France, the modern Rousseau, and had enjoyed the marvellous irony and eloquence of his writings, which, while they delight the society in which he lives, may well be one of the causes that lead to its eventual destruction. The solution of the problem of Aesthetic is not in the gift of the Muses.
