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.
Thomas Hobbes, Leviathan, 1651.
