And whereas sense and memory are but knowledge of fact, which is a thing past and irrevocable, science is the knowledge of consequences, and dependence of one fact upon another; by which, out of that we can presently do, we know how to do something else when we will, or the like, another time: because when we see how anything comes about, upon what causes, and by what manner; when the like causes come into our power, we see how to make it produce the like effects.
Quotations by:
Hobbes, Thomas
The secret thoughts of a man run over all things holy, prophane, clean, obscene, grave, and light, without shame, or blame.
From the same it proceedeth that men give different names to one and the same thing from the difference of their own passions: as they that approve a private opinion call it opinion; but they that mislike it, heresy: and yet heresy signifies no more than private opinion; but has only a greater tincture of choler.
Ignorance of remote causes disposeth men to attribute all events to the causes immediate and instrumental: for these are all the causes they perceive.
Whatsoever therefore is consequent to a time of Warre, where every man is Enemy to every man; the same is consequent to the time, wherein men live without other security, than what their own strength, and their own invention shall furnish them withall. In such condition, there is no place for Industry; because the fruit thereof is uncertain; and consequently no Culture of the Earth; no Navigation, nor use of the commodities that may be imported by Sea; no commodious Building; no Instruments of moving, and removing such things as require much force; no Knowledge of the face of the Earth; no account of Time; no Arts; no Letters; no Society; and which is worst of all, continuall feare, and danger of violent death; And the life of man, solitary, poore, nasty, brutish, and short.
Hereby it is manifest that during the time men live without a common power to keep them all in awe, they are in that condition which is called war; and such a war as is of every man against every man.
For such is the nature of men that howsoever they may acknowledge many others to be more witty, or more eloquent or more learned, yet they will hardly believe there be many so wise as themselves; for they see their own wit at hand, and other men’s at a distance.
To this war of every man against every man, this also is consequent; that nothing can be unjust. The notions of right and wrong, justice and injustice, have there no place. Where there is no common power, there is no law; where no law, no injustice. Force and fraud are in war the two cardinal virtues.
Leisure is the mother of Philosophy; and Common-wealth, the mother of Peace, and Leisure: Where first were great and flourishing Cities, there was first the study of Philosophy.
