There are some natures purely contemplative and antipathetic to action, who nevertheless, under a mysterious and inexplicable impulse, sometimes act with a rapidity of which they would have believed themselves incapable. Such a one is he who, fearing to find some new vexation awaiting him at his lodgings, prowls about in a cowardly fashion before the door without daring to enter; such a one is he who keeps a letter fifteen days without opening it, or only makes up his mind at the end of six months to undertake a journey that has been a necessity for a year past. Such beings sometimes feel themselves precipitately thrust towards action, like an arrow from a bow. The novelist and the physician, who profess to know all things, yet cannot explain whence comes this sudden and delirious energy to indolent and voluptuous souls; nor how, incapable of accomplishing the simplest and most necessary things, they are at some certain moment of time possessed by a superabundant hardihood which enables them to execute the most absurd and even the most dangerous acts. One of my friends, the most harmless dreamer that ever lived, at one time set fire to a forest, in order to ascertain, as he said, whether the flames take hold with the easiness that is commonly affirmed. His experiment failed ten times running, on the eleventh it succeeded only too well. Another lit a cigar by the side of a powder barrel, _in order to see, to know, to tempt Destiny_, for a jest, to have the pleasure of suspense, for no reason at all, out of caprice, out of idleness. This is a kind of energy that springs from weariness and reverie; and those in whom it manifests so stubbornly are in general, as I have said, the most indolent and dreamy beings. Another so timid that he must cast down his eyes before the gaze of any man, and summon all his poor will before he dare enter a café or pass the pay-box of a theatre, where the ticket-seller seems, in his eyes, invested with all the majesty of Minos, Æcus, and Rhadamanthus, will at times throw himself upon the neck of some old man whom he sees in the street, and embrace him with enthusiasm in sight of an astonished crowd. Why? Because--because this countenance is irresistibly attractive to him? Perhaps; but it is more legitimate to suppose that he himself does not know why. I have been more than once a victim to these crises and outbreaks which give us cause to believe that evil-meaning demons slip into us, to make us the ignorant accomplices of their most absurd desires. One morning I arose in a sullen mood, very sad, and tired of idleness, and thrust as it seemed to me to the doing of some great thing, some brilliant act--and then, alas, I opened the window.
