Aristotle's Conception of Nature

Aristotle's conception of nature is teleological. This word comes from the greek telos, which means end or purpose. There is no goal or purpose to a giraffe, lovely though she may be. The parts of animals perform certain functions such as camouflage,. reaching leaves and watching for enemies. But they do not have final causes. And the reason for the difference is that the goal of a man made thing is imposed by the human who makes it.
