'Charm' - which means the power to effect work without employing brute force - is indispensable to women. Charm is a woman's strength just as strength is a man's charm.

Havelock Ellis

The law in question asserts, that the quantity of force which can be brought into action in the whole of Nature is unchangeable, and can neither be increased nor diminished.

Hermann von Helmholtz

Ideas improve. The meaning of words participates in the improvement. Plagiarism is necessary. Progress implies it. It embraces an author's phrase, makes use of his expressions, erases a false idea, and replaces it with the right idea.

Guy Debord

In effect, to follow, not to force the public inclination; to give a direction, a form, a technical dress, and a specific sanction, to the general sense of the community, is the true end of legislature.

Edmund Burke

Indeed some degree of affectation is as necessary to the mind as dress is to the body; we must overact our part in some measure, in order to produce any effect at all.

William Hazlitt
