Ten quotes from the book Leviathan, likely the most significant work of political philosophy by Thomas Hobbes. Here are some of the most popular quotes from the book:

1. “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.”
2. “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.”
3. “So that in the nature of man, we find three principal causes of quarrel. First, competition; secondly, diffidence; thirdly, glory.”
4. “The passions that incline men to peace are: fear of death; desire of such things as are necessary to commodious living; and a hope by their industry to obtain them.”
5. “In the first place, I put for a general inclination of all mankind, a perpetual and restless desire of power after power, that ceaseth only in death.”
6. “The condition of man… is a condition of war of every one against every one.”
7. “And covenants, without the sword, are but words and of no strength to secure a man at all.”
8. “A law of nature, lex naturalis, is a precept or general rule, found out by reason, by which a man is forbidden to do that which is destructive of his life, or takes away the means of preserving the same.”
9. “And, in this law of nature, consisteth the fountain of obligation; for every man that hath a sovereign power to cause this law to be followed, is thereby obliged to preserve the peace and security of his people, and is to be reckoned an author of all the crimes that are committed in a commonwealth.”
10. “And therefore if a man be trusted to pass sentence, and doom the right, he is trusted, or ought to be trusted, with the sword, at least, with the sword to defend the condemned, and right, if his sentence be unjust.”
