Principle Quotes - page 36
I flatter my self to have demonstrated that, neither the Friendly Qualities and kind Affections that are natural to Man, nor the real Virtues he is capable of acquiring by Reason and Self-Denial, are the Foundation of Society; but that what we call Evil in this World, Moral as well as Natural, is the grand Principle that makes us sociable Creatures, the solid Basis, the Life and Support of all Trades and Employments without Exception: That there we must look for the true Origin of all Arts and Sciences, and that the Moment Evil ceases, the Society must be spoiled, if not totally dissolved.
Bernard Mandeville
Some American writer has said "the snakes in this district may be divided into one species-the venomous”. The same principle applies here. Postage-Stamp-Cases may be divided into one species, the "Wonderland”. Imitations of it will soon appear, no doubt: but they cannot include the two Pictorial Surprises, which are copyright.You don't see why I call them 'Surprises'? Well, take the Case in your left hand, and regard it attentively. You see Alice nursing the Duchess's Baby ? (An entirely new combination, by the way : it doesn't occur in the book.) Now, with your right thumb and forefinger, lay hold of the little book, and suddenly pull it out. The Baby has turned into a Pig I If that doesn't surprise you, why, I suppose you wouldn't be surprised if your own Mother-in-law suddenly turned into a Gyroscope!
Lewis Carroll
We are... bound to attach the greatest importance to the preliminary step taken by Lavoisier, who is even more justly called the father of modern chemistry than Kepler is called the father of modern astronomy. The exact claims of Lavoisier to this important place in the history of chemistry have been variously stated: ...since his time, and greatly through his labours, the quantitative method has been established as the ultimate test of chemical facts; the principle of this method being the rule that in all changes of combination and reaction, the total weight of the various ingredients-be they elementary bodies or compounds-remains unchanged. The science of chemistry was thus established upon an exact, a mathematical basis. By means of this method Lavoisier, utilising and analysing the results gained by himself and others before him, notably those of Priestley, Cavendish, and Black, succeeded in destroying the older theory of combustion, the so-called phlogistic theory.
Antoine Lavoisier
Philosophers are generally persuaded, that the sensations of heat and cold are occasioned by the presence or absence, in degree, of certain principle or quality denominated fire or heat... It is most probable, that all substances whatever contain more or less of this principle. Respecting the nature of the principle, however, there is a diversity of sentiment : some supposing it a substance, others a quality, or property of substance. Boerhaave, followed by most of the moderns, is of the former opinion; Newton, with some others, are of the latter; these conceive heat to consist in an internal vibratory motion of the particles of bodies.
John Dalton
