“The true Mathematical and Mechanical Form of all manner of Arches for building with the true butment necessary to each of them, a Problem which no Architectonick Writer hath ever yet attempted, much less perform'd.”

—  Robert Hooke

...Ut pendet continaum flexile, sic stabit contiguum rigidum, which is the Linea Catenaria.
Tr: As hangs the flexible line, so but inverted will stand the rigid arch.

“But the success of attempts in this way, must evidently depend much on the manner of conducting them.”

Report on Manufactures (1791)
Context: The propriety of stimulating by rewards the invention and introduction of useful improvements, is admitted without difficulty. But the success of attempts in this way, must evidently depend much on the manner of conducting them. It is probable that the placing of the dispensation of those rewards under some proper discretionary direction, where they may be accompanied by collateral expedients, will serve to give them the surest efficacy. It seems impracticable to apportion, by general rules, specific compensations for discoveries of unknown and disproportionate utility.

“The forbearing use of power does not only form a touchstone, but the manner in which an individual enjoys certain advantages over others is a test of a true gentleman.”

Robert E. Lee (1807–1870) Confederate general in the Civil War

"Definition of a Gentleman" http://xroads.virginia.edu/~CAP/LEE/gentdef.html, a memorandum found in his papers after his death, as quoted in Lee the American (1912) by Gamaliel Bradford, p. 233
Context: The forbearing use of power does not only form a touchstone, but the manner in which an individual enjoys certain advantages over others is a test of a true gentleman.
The power which the strong have over the weak, the employer over the employed, the educated over the unlettered, the experienced over the confiding, even the clever over the silly — the forbearing or inoffensive use of all this power or authority, or a total abstinence from it when the case admits it, will show the gentleman in a plain light.
The gentleman does not needlessly and unnecessarily remind an offender of a wrong he may have committed against him. He cannot only forgive, he can forget; and he strives for that nobleness of self and mildness of character which imparts sufficient strength to let the past be but the past. A true man of honor feels humbled himself when he cannot help humbling others.

“All tales may come true; and yet, at the last, redeemed, they may be as like and unlike the forms that we give them as Man, finally redeemed, will be like and unlike the fallen that we know.”

On Fairy-Stories (1939)
Context: The Evangelium has not abrogated legends; it has hallowed them, especially the "happy ending." The Christian has still to work, with mind as well as body, to suffer, hope, and die; but he may now perceive that all his bents and faculties have a purpose, which can be redeemed. So great is the bounty with which he has been treated that he may now, perhaps, fairly dare to guess that in Fantasy he may actually assist in the effoliation and multiple enrichment of creation. All tales may come true; and yet, at the last, redeemed, they may be as like and unlike the forms that we give them as Man, finally redeemed, will be like and unlike the fallen that we know.
