“A permanent alteration of form limits the strength of materials with regard to practical purposes, almost as much as fracture; since, in general, the force which is capable of producing this effect is sufficient, with a small addition, to increase it till fracture takes place.”

“[An elaborated culture has a] density, complexity, and historical-semantic value that is so strong as to make politics possible… Gramsci's insight is to have recognised that subordination, fracturing, diffusion, reproducing, as much as producing, creating, forcing, guiding, are necessary aspects of elaboration.”

Edward Said (1935–2003) Professor of English and literature

Quoted in Richard Middleton, Studying Popular Music (Philadelphia: Open University Press, 1990, ISBN 0-335-15275-9), p. 248

“[O]f that scientifically practical skill which produces the greatest effect with the least possible expenditure of material and work, the instances are comparatively rare. In too many cases we see the strength and the stability which ought to be given by the skilful arrangement of the parts of a structure supplied by means of clumsy massiveness, and of lavish expenditure of material, labour, and money; and the evil is increased by a perversion of the public taste, which causes works to be admired, not in proportion to their fitness for their purposes, or to the skill evinced in attaining that fitness, but in proportion to their size and cost.”

William John Macquorn Rankine (1820–1872) civil engineer

“The effect of the land reform bringing land to the peasant masses is to enhance their enthusiasm and their zeal in increasing production and taking part in the war of resistance, and consequently the resistance forces will grow in strength.”

Trường Chinh (1907–1988) former General Secretary of the Communist Party of Vietnam (1907-1988)

“For evil to take place, the acts of a few people are not sufficient; the great majority also has to remain indifferent. That is something of which we are all quite capable.”

“Every exchange which takes place in a country, effects a distribution of its produce better adapted to the wants of society….”

Thomas Robert Malthus Principles of Political Economy

Book II, Chapter I, On the Progress of Wealth, Section VIII, p. 382-383
Principles of Political Economy (Second Edition 1836)
Context: Every exchange which takes place in a country, effects a distribution of its produce better adapted to the wants of society....
If two districts, one of which possessed a rich copper mine, and the other a rich tin mine, had always been separated by an impassable river or mountain, there can be no doubt that an opening of a communication, a greater demand would take place, and a greater price be given for both the tin and the copper; and this greater price of both metals, though it might be only temporary, would alone go a great way towards furnishing the additional capital wanted to supply the additional demand; and the capitals of both districts, and the products of both mines, would be increased both in quantity and value to a degree which could not have taken place without the this new distribution of the produce, or some equivalent to it.

“No form remains permanently in a substance; a constant change takes place, one form is taken off and another is put on.”

“Since reasoning, or inference, the principal subject of logic, is an operation which usually takes place by means of words, and in complicated cases can take place in no other way: those who have not a thorough insight into both the signification and purpose of words, will be under chances, amounting almost to certainty, of reasoning or inferring incorrectly.”

John Stuart Mill book A System of Logic

“The material in all elementary parts of a structure must have the properties of resistence to all internal forces produced by general loading conditions and by the action of any exterior force.”

Eduardo Torroja (1899–1961) Spanish architect

p, 125
Philosophy of Structures (1958)

“The external work of man is of the most varied kind as regards the force or ease, the form and rapidity, of the motions used on it, and the kind of work produced.”

Hermann von Helmholtz (1821–1894) physicist and physiologist

"On the Conservation of Force" (1862), p. 280
Popular Lectures on Scientific Subjects (1881)
Context: The external work of man is of the most varied kind as regards the force or ease, the form and rapidity, of the motions used on it, and the kind of work produced. But both the arm of the blacksmith who delivers his powerful blows with the heavy hammer, and that of the violinist who produces the most delicate variations in sound, and the hand of the lacemaker who works with threads so fine that they are on the verge of the invisible, all these acquire the force which moves them in the same manner and by the same organs, namely, the muscles of the arm. An arm the muscles of which are lamed is incapable of doing any work; the moving force of the muscle must be at work in it, and these must obey the nerves, which bring to them orders from the brain. That member is then capable of the greatest variety of motions; it can compel the most varied instruments to execute the most diverse tasks.

“The tremendous and highly complex industrial development which went on with ever accelerated rapidity during the latter half of the nineteenth century brings us face to face, at the beginning of the twentieth, with very serious social problems. The old laws, and the old customs which had almost the binding force of law, were once quite sufficient to regulate the accumulation and distribution of wealth. Since the industrial changes which have so enormously increased the productive power of mankind, they are no longer sufficient.”

Theodore Roosevelt (1858–1919) American politician, 26th president of the United States

1900s, First Annual Message to Congress (1901)

“A permanent alteration of form limits the strength of materials with regard to practical purposes, almost as much as fracture; since, in general, the force which is capable of producing this effect is sufficient, with a small addition, to increase it till fracture takes place.”
