Rousseau’s own Arcadian memories are usually not of reading, like Hazlitt’s, but of actual incidents, though he does not hesitate to alter these incidents freely, as in his account of his stay at Les Charmettes, and to accommodate them to his dream. He neglected the real Madame de Warens at the very time that he cherished his recollection of her because this recollection was the idealized image of his own youth. The yearning that he expresses at the beginning of his fragmentary Tenth Promenade, written only a few weeks before his death, is for this idyllic period rather than for an actual woman.[168] A happy memory, says Musset, repeating Rousseau, is perhaps more genuine than happiness itself. Possibly the three best known love poems of Lamartine, Musset, and Hugo respectively--“Le Lac,” “Souvenir,” and “La Tristesse d’Olympio,” all hinge upon impassioned recollection and derive very directly from Rousseau. Lamartine in particular has caught in the “Le Lac” the very cadence of Rousseau’s reveries.[169] Impassioned recollection may evidently be an abundant source of genuine poetry, though not, it must be insisted, of the highest poetry. The predominant rôle that it plays in Rousseau and many of his followers is simply a sign of an unduly dalliant imagination. Experience after all has other uses than to supply furnishings for the tower of ivory; it should control the judgment and guide the will; it is in short the necessary basis of conduct. The greater a man’s moral seriousness, the more he will be concerned with doing rather than dreaming (and I include right meditation among the forms of doing). He will also demand an art and literature that reflect this his main preoccupation. Between Wordsworth’s definition of poetry as “emotion recollected in tranquillity,” and Aristotle’s definition of poetry as the imitation of human action according to probability or necessity, a wide gap plainly opens. One may prefer Aristotle’s definition to that of Wordsworth and yet do justice to the merits of Wordsworth’s actual poetical performance. Nevertheless the tendency to put prime emphasis on feeling instead of action shown in the definition is closely related to Wordsworth’s failure not only in dramatic but in epic poetry, in all poetry in short that depends for its success on an element of plot and sustained narrative.
