It must be admitted, however, that Renan’s attitude to the problems of knowledge was largely sceptical. While, as we shall see in the following chapter, he extolled science, his attitude to belief and to knowledge was irritating in its vagueness and changeableness. He appeared to pose too much as a _dilettante_ making a show of subtle intellect, rather than a serious thinker of the first rank. His eminence and genius are unquestioned, but he played in a bewitching and frequently bewildering manner with great and serious problems, and one cannot help wishing that this great intellect of his—and it was unquestionably great—was not more steady and was not applied by its owner more steadfastly and courageously to ultimate problems. His writings reflect a bewildering variety of contradictory moods, playful, scathing, serious and mocking. Indeed, he replied in his _Feuilles detachées_ (1892) to the accusations of Amiel by insisting that irony is the philosopher’s last word. For him as for his brilliant fellow-countryman, Anatole France, ironical scepticism is the ultimate product of his reflection upon life. His _Examen de Conscience_ philosophique is his Confession of Faith, written four years before his death, in which he tries to defend his sceptical attitude and to put forward scepticism as an apology for his own uncertainty and his paradoxical changes of view. Irony intermingles with his doubt here too. We do not know, he says, ultimate reality; we do not know whether there be any purpose or end in the universe at all. There may be, but on the other hand it may be a farce and fiasco. By refusing to believe in anything, rejecting both alternatives, Renan argues, with a kind of mental cowardice, we avoid the consequence of being absolutely deceived. He recommended an adoption of mixed belief and doubt, optimism and irony.
This is a surprising attitude in a philosopher and is not characteristic of great modern thinkers, most of whom prefer belief (hypothetical although that be) to non-belief. Doubtless Renan’s early training had a psychological effect which operated perhaps largely unconsciously throughout his life, and his literary and linguistic ability seems to have given him a reputation which was rather that of a man of letters than a philosopher. He had not the mental strength or frankness to face alternatives squarely and to decide to adopt one. Consequently he merited the application of the old proverb about being between two stools. This application was actually made to Renan’s attitude in a critical remark by Renouvier in his _Esquisse d’une Classification des Doctrines philosphiques_.[16] Renouvier had no difficulty in pointing out that the man who hesitates deprives himself of that great reality, the exercise of his own power of free choice, in itself valuable and more akin to reality (whatever be the choice) than a mere “sitting on the fence,” an attitude which, so far from assuring one of getting the advantages of both possibilities as Renan claims, may more justly seem to deprive one of the advantages in both directions. The needs of life demand that we construct beliefs of some sort. We may be wrong and err, but pure scepticism such as Renan advocated is untenable. Life, if it is to be real and earnest, demands of us that we have faith in _some_ values, that we construct _some_ beliefs, _some_ hypotheses, by which we may work.
