[Alchemists] finde out men so covetous of so much happiness, whom they easily perswade that they shall finde greater Riches in Hydargyrie [mercury], than Nature affords in Gold. Such, whom although they have twice or thrice already been deluded, yet they have still a new Device wherewith to deceive um again; there being no greater Madness…. So that the smells of Coles, Sulphur, Dung, Poyson, and Piss, are to them a greater pleasure than the taste of Honey; till their Farms, Goods, and Patrimonies being wasted, and converted into Ashes and Smoak, when they expect the rewards of their Labours, births of Gold, Youth, and Immortality, after all their Time and Expences; at length, old, ragged, famisht, with the continual use of Quicksilver [mercury] paralytick, onely rich in misery, … a laughing-stock to the people: … compell’d to live in the lowest degree of poverty, and … at length compell’d thereto by Penury, they fall to Ill Courses, as Counterfeiting of Money.

Even now, the imprisoned winds which the earliest poet made the Grecian warrior bear for the protection of his fragile bark; or those which, in more modern times, the Lapland wizards sold to the deluded sailors;—these, the unreal creations of fancy or of fraud, called, at the command of science, from their shadowy existence, obey a holier spell: and the unruly masters of the poet and the seer become the obedient slaves of civilized man.

The Mathematics, I say, which effectually exercises, not vainly deludes or vexatiously torments studious Minds with obscure Subtilties, perplexed Difficulties, or contentious Disquisitions; which overcomes without Opposition, triumphs without Pomp, compels without Force, and rules absolutely without Loss of Liberty; which does not privately over-reach a weak Faith, but openly assaults an armed Reason, obtains a total Victory, and puts on inevitable Chains; whose Words are so many Oracles, and Works as many Miracles; which blabs out nothing rashly, nor designs anything from the Purpose, but plainly demonstrates and readily performs all Things within its Verge; which obtrudes no false Shadow of Science, but the very Science itself, the Mind firmly adhering to it, as soon as possessed of it, and can never after desert it of its own Accord, or be deprived of it by any Force of others: Lastly the Mathematics, which depends upon Principles clear to the Mind, and agreeable to Experience; which draws certain Conclusions, instructs by profitable Rules, unfolds pleasant Questions; and produces wonderful Effects; which is the fruitful Parent of, I had almost said all, Arts, the unshaken Foundation of Sciences, and the plentiful Fountain of Advantage to human Affairs.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
