“I set out to discover the why of it, and to transform my pleasure into knowledge.”

Inaugural Address of the Great Exhibition of the Works of Industry of All Nations, London (1851).
Context: Nobody who has paid any attention to the peculiar features of our present era will doubt for a moment that we are living at a period of most wonderful transition which tends rapidly to the accomplishment that great end to which, indeed, all history points—the realization of the unity of mankind.... The distances which separated the different nations and parts of the globe are rapidly vanishing before the achievements of modern invention, and we can traverse them with incredible ease; the languages of all nations are known, and their acquirement placed within the reach of everybody; thought is communicated with the rapidity and even by the power of lightning... The knowledge acquired becomes at once the property of all of the community at large... no sooner is a discovery or invention made, than it is already improved upon and surpassed by competing efforts: the products of all quarters of the globe are placed at our disposal, and we have only to choose which is the best and the cheapest for our purposes, and the powers of production are entrusted to the stimulus of competition and capital.... Science discovers these laws of power, motion and transformation; industry applies them to raw matter which the earth yields us in abundance, but which becomes valuable only by knowledge.

Reported in Friends' Intelligencer and Journal (1898) Volume 55, p. 210. No earlier source for this quotation is given, or has otherwise been identified. Several variants are found elsewhere, e.g., ""I cannot allow my opponent's Ignorance, however vast, to offset my knowledge, however small," reported in The Kingston Daily Freeman, Volume 33, Number 167, 3 May 1904, p. 4; and "my knowledge, however small, must outweigh your ignorance, however large," reported in Semi-Centennial (1939), p. 5, by Leonard Bacon, the great-grandson of the preacher. This quote has recently been mis-attributed to William James.

Context: What transforms this world is — knowledge. Do you see what I mean? Nothing else can change anything in this world. Knowledge alone is capable of transforming the world, while at the same time leaving it exactly as it is. When you look at the world with knowledge, you realize that things are unchangeable and at the same time are constantly being transformed. You may ask what good it does us. Let's put it this way — human beings possess the weapon of knowledge in order to make life bearable. For animals such things aren't necessary. Animals don't need knowledge or anything of the sort to make life bearable. But human beings do need something, and with knowledge they can make the very intolerableness of life a weapon, though at the same time that intolerableness is not reduced in the slightest. That's all there is to it.
