Humans are inherently evil.
Thomas Hobbes (1588–1679) was an English philosopher and the author of the famous book Leviathan. Famously, Hobbes declared that primitive human life was "solitary, poor, nasty, brutish, and short."
I use Hobbes to illustrate the pessimistic view o... f "natural man." That is, as illustrated by Hobbes' famous summation, Hobbes felt that the "natural" state of man was akin to being beast-like. Thus, it is civilization that steps in and recuses humanity from our primal depravity. In this view, human nature is a nasty thing that human culture rescues. In Hobbes' view, being "civilized" is good and being a "savage" is bad
