Thomas Hobbes (1588-1679) was a great English political philosopher, most famous for his book Leviathan. In this book, he described human nature and the necessity of governments and societies. In the state of nature, while some men may be stronger or smarter than others, none are so far above as to be beyond fear of another man doing harm. Thus, each of us has rights to everything, and due to the scarcity of these things, we are in a constant state of war. However, man has a self-interested desire to end war, and so he forms societies by entering into a social contract. According to Hobbesism, such a society needs a leader to whom all members of that society surrender their authority, in order to secure a common defense. This benevolent sovereign is chosen at random and becomes the Leviathan, an unquestionable authority.
Hobbes also wrote numerous other books on political philosophy and other matters, providing a fairly perceptive account of human nature as self-interested cooperation. He was also a contemporary of Descartes and wrote one of the replies to Descartes' Meditations.
- Desire to know why, and how, curiosity; such as is in no living creature but man: so that man is distinguished, not only by his reason, but also by this singular passion from other animals; in whom the appetite of food, and other pleasures of sense, by predominance, take away the care of knowing causes; which is a lust of the mind, that by a perseverance of delight in the continual and indefatigable generation of knowledge, exceedeth the short vehemence of any carnal pleasure.
