“The wheel may be one of those cases where the engineering solution can be seen in plain view, yet be unattainable in evolution because it lies [on] the other side of a deep valley, cutting unbridgeably across the massif of Mount Improbable.”

Statement of 1925, as quoted in Lord Reading (1967) by H. Montgomery Hyde, p. 387.

A similar statement (perhaps used in a later declaration) has been quoted at the UFW site http://www.ufw.org/_page.php?menu=research&inc=history/09.html: "Across the San Joaquin valley, across California, across the entire nation, wherever there are injustices against men and women and children who work in the fields — there you will see our flags — with the black eagle with the white and red background, flying. Our movement is spreading like flames across a dry plain."

Fiction, The Colour Out of Space (1927)
Context: West of Arkham the hills rise wild, and there are valleys with deep woods that no axe has ever cut. There are dark narrow glens where the trees slope fantastically, and where thin brooklets trickle without ever having caught the glint of sunlight. On the gentle slopes there are farms, ancient and rocky, with squat, moss-coated cottages brooding eternally over old New England secrets in the lee of great ledges; but these are all vacant now, the wide chimneys crumbling and the shingled sides bulging perilously beneath low gambrel roofs. The old folk have gone away, and foreigners do not like to live there. French-Canadians have tried it, Italians have tried it, and the Poles have come and departed. It is not because of anything that can be seen or heard or handled, but because of something that is imagined. The place is not good for imagination, and does not bring restful dreams at night.

Progress and Poverty (1879)
Context: This strange and unnatural spectacle of large numbers of willing men who cannot find employment is enough to suggest the true cause to whosoever can think consecutively. For, though custom has dulled us to it, it is a strange and unnatural thing that men who wish to labor, in order to satisfy their wants, cannot find the opportunity — as, since labor is that which produces wealth, the man who seeks to exchange labor for food, clothing, or any other form of wealth, is like one who proposes to give bullion for coin, or wheat for flour. We talk about the supply of labor and the demand for labor, but, evidently, these are only relative terms. The supply of labor is everywhere the same — two hands always come into the world with one mouth, twenty-one boys to every twenty girls; and the demand for labor must always exist as long as men want things which labor alone can procure. We talk about the "want of work," but, evidently, it is not work that is short while want continues; evidently, the supply of labor cannot be too great, nor the demand for labor too small, when people suffer for the lack of things that labor produces. The real trouble must be that supply is somehow prevented from satisfying demand, that somewhere there is an obstacle which prevents labor from producing the things that laborers want.
Take the case of any one of these vast masses of unemployed men, to whom, though he never heard of Malthus, it today seems that there are too many people in the world. In his own wants, in the needs of his anxious wife, in the demands of his half-cared-for, perhaps even hungry and shivering children, there is demand enough for labor, Heaven knows! In his own willing hands is the supply. Put him on a solitary island, and though cut off from all the enormous advantages which the co-operation, combination, and machinery of a civilized community give to the productive powers of man yet his two hands can fill the mouths and keep warm the backs that depend upon them. Yet where productive power is at its highest development they cannot. Why? Is it not because in the one case he has access to the material and forces of nature, and in the other this access is denied?
Is it not the fact that labor is thus shut off from nature which can alone explain the state of things that compels men to stand idle who would willingly supply their wants by their labor? The proximate cause of enforced idleness with one set of men may be the cessation of demand on the part of other men for the particular things they produce, but trace this cause from point to point, from occupation to occupation, and you will find that enforced idleness in one trade is caused by enforced idleness in another, and that the paralysis which produces dullness in all trades cannot be said to spring from too great a supply of labor or too small a demand for labor, but must proceed from the fact that supply cannot meet demand by producing the things which satisfy want and are the object of labor.
