But what, after all, is this "new soul" which Montaigne succeeded in putting into our western civilisation at the very moment when Catholic and Protestant were so furiously striving for the mastery? What is this new tone, this new temper, this new temperamental atmosphere which, in the intervals of his cautious public work and his lazy compiling of scrap-books from the classics, he managed to fling abroad upon the air?
It is a spiritual ingredient, composed, when one comes to analyse it, of two chemical elements; of what might be called aesthetic egoism and of what we know as philosophic scepticism. Let us deal with the former of these two elements first.
Egoism, in the new psychological sense of the word, may be regarded as the deliberate attempt in an individual's life to throw the chief interest and emphasis of his days upon the inward, personal, subjective impressions produced by the world, rather than upon outward action or social progress. Egoism does not necessarily imply the invidious stigma of selfishness. Goethe, the greatest of all egoists, was notoriously free from such a vice. "Who," cried Wieland, when they first met at Weimar, "who can resist the unselfishness of this man?"
Egoism does not necessarily imply "egotism," though it must be confessed that in Montaigne's case, though not in Goethe's, there may have been a touch of that less generous attribute.
Egoism is an intellectual gesture, a spiritual attitude, a temperamental atmosphere. It is a thing which implies a certain definite philosophical mood in regard to the riddle of existence; though, of course, between individual egoists there may be wide gulfs of personal divergence.
Between Montaigne and Goethe, for instance, there is an immense difference. Goethe's egoism was creative; Montaigne's receptive. Goethe's was many-sided; driven forward by a tremendous demonic urge toward the satisfaction of a curiosity which was cosmic and universal. Montaigne's was in a certain sense narrow, limited, cautious, earth-bound. It had nothing of the large poetic sweep, nothing of the vast mystical horizons and huge imaginative vistas of the great German. But on the other hand, it was closer to the soil, homelier, more humorous, in a certain measure more natural, normal and human.
This "cult of egoism" is obviously not entirely modern. Traces of it, aspects of it, fragments and morsels of it, have existed from all time. It was the latent presence of this quality in his great Romans, much more than their mere "outward triumphs," which led him to brood so incessantly upon their memories.
But Montaigne himself was the first of all writers to give palpable intellectual shape to this diffused spiritual temper.
In recent times, some of the most fascinating of our literary guides have been philosophical egotists. Whitman, Matthew Arnold, Emerson, Pater, Stendhal, Maurice Barrès (in his earlier work), de Gourmont, D'Annunzio, Oscar Wilde—are all, in their widely different ways, masters of the same cult.
The out-looking activities and the out-looking social interests of Voltaire or Renan, or Anatole France, give to these great writers quite a different psychological tone. The three I have just mentioned are all too inveterately spirits of mockery even to take seriously their own "sensations and ideas"; and however ironical and humorous an egoist may be with regard to other people's impressions, with regard to his own he is grave, intent, preoccupied, almost solemn.
