Now not only are men governed by their imaginations (the imagination, as Pascal says, disposes of everything), but the type of imagination by which most men are governed may be defined in the widest sense of the word as romantic. Nearly every man cherishes his dream, his conceit of himself as he would like to be, a sort of “ideal” projection of his own desires, in comparison with which his actual life seems a hard and cramping routine. “Man must conceive himself what he is not,” as Dr. Johnson says, “for who is pleased with what he is?” The ample habitation that a man rears for his fictitious or “ideal” self often has some slight foundation in fact, but the higher he rears it the more insecure it becomes, until finally, like Perrette in the fable, he brings the whole structure down about his ears by the very gesture of his dream. “We all of us,” La Fontaine concludes in perhaps the most delightful account of the romantic imagination in literature, “wise as well as foolish, indulge in daydreams. There is nothing sweeter. A flattering illusion carries away our spirits. All the wealth in the world is ours, all honors and all women,”[52] etc. When Johnson descants on the “dangerous prevalence of imagination,”[53] and warns us to stick to “sober probability,” what he means is the dangerous prevalence of day-dreaming. The retreat of the Rousseauist into some “land of chimeras” or tower of ivory assumes forms almost incredibly complex and subtle, but at bottom the ivory tower is only one form of man’s ineradicable longing to escape from the oppression of the actual into some land of heart’s desire, some golden age of fancy. As a matter of fact, Rousseau’s imaginative activity often approaches very closely to the delights of day-dreaming as described by La Fontaine. He was never more imaginative, he tells us, than when on a walking-trip--especially when the trip had no definite goal, or at least when he could take his time in reaching it. The _Wanderlust_ of body and spirit could then be satisfied together. Actual vagabondage seemed to be an aid to the imagination in its escape from verisimilitude. One should note especially Rousseau’s account of his early wandering from Lyons to Paris and the airy structures that he raised on his anticipations of what he might find there. Inasmuch as he was to be attached at Paris to the Swiss Colonel Godard, he already traced for himself in fancy, in spite of his short-sightedness, a career of military glory. “I had read that Marshal Schomberg was short-sighted, why shouldn’t Marshal Rousseau be so too?” In the meanwhile, touched by the sight of the groves and brooks, “I felt in the midst of my glory that my heart was not made for so much turmoil, and soon without knowing how, I found myself once more among my beloved pastorals, renouncing forever the toils of Mars.”
