Aristotle was one of the greatest philosophers who ever lived and the first genuine scientist in history. He made pioneering contributions to all fields of philosophy and science, he invented the field of formal logic, and he identified the various scientific disciplines and explored their relationships to each other.

In his metaphysics, he claims that there must be a separate and unchanging being that is the source of all other beings. In his ethics, he holds that it is only by becoming excellent that one could achieve eudaimonia, a sort of happiness or blessedness that constitutes the best kind of human life.

Aristotle's logic, especially his theory of the syllogism, has had an unparalleled influence on the history of Western thought.

“Education is bitter, but its fruit is sweet.” ~ Aristotle “All knowledge should be subject to examination and reason.” ~Aristotle “Man is a political being.” ~Aristotle “We are what we do repeatedly. Separate him from law and justice and he is the worst.”
