What influences did ancient Greek Philosophers have on the European culture?

Greek thought, thanks to the Greek philosophers, is still prevalent in our modern day civilization. Not only did these philosophers forever change and shape the way that we view the world around us, but several of them had such outstanding ideas which are now considered the precursors of modern science. Democritus (the "laughing philosopher"), for example, came up with the idea of atoms to explain what made up the soul, and he decided that these things were pieces of matter impossible to destroy. We are also still taught the works of Plato, Socrates, Aristotle, and many others.
