What is thought? Where does it reside? How is it formed? Who gives me thoughts during my sleep? Is it in virtue of my will that I think? No, for always during sleep, and often when I am awake, I have ideas against, or at least without, my will. These ideas, long forgotten, long put away, and banished in the lumber room of my brain, issue from it without any effort or volition of mine, and suddenly present themselves to my memory, which had, perhaps, previously made various vain attempts to recall them. External objects have not the power of forming ideas in me, for nothing can communicate what it does not possess; I am well assured that they are not given me by myself, for they are produced without my orders. Who then produces them in me? Whence do they come? Whither do they go? Fugitive phantoms! What invisible hand produces and disperses you? Why, of all the various tribes of animals, has man alone the mad ambition of domineering over his fellow? Why and how could it happen, that out of a thousand millions of men, more than nine hundred and ninety-nine have been sacrificed to this mad ambition? How is it that reason is a gift so precious that we would none of us lose it for all the pomp or wealth of the world, and yet at the same time that it has merely served to render us, in almost all cases, the most miserable of beings? Whence comes it, that with a passionate attachment to truth, we are always yielding to the most palpable impostures? Why do the vast tribes of India, deceived and enslaved by the bonzes, trampled upon by the descendant of a Tartar, bowed down by labor, groaning in misery, assailed by diseases, and a mark for all the scourges and plagues of life, still fondly cling to that life? Whence comes evil, and why does it exist? O atoms of a day! O companions in littleness, born like me to suffer everything, and be ignorant of everything!--are there in reality any among you so completely mad as to imagine you know all this, or that you can solve all these difficulties? Certainly there can be none. No; in the bottom of your heart you feel your own nothingness, as completely as I do justice to mine. But you are nevertheless arrogant and conceited enough to be eager for our embracing your vain systems; and not having the power to tyrannize over our bodies, you aim at becoming the tyrants of our souls. IMAGINATION. SECTION I. Imagination is the power which every being, endowed with perception and reason, is conscious he possesses of representing to himself sensible objects. This faculty is dependent upon memory. We see men, animals, gardens, which perceptions are introduced by the senses; the memory retains them, and the imagination compounds them. On this account the ancient Greeks called the muses, "the daughters of memory."
