According to Leibniz, the indivisible units that compose everything in the universe. All monads are characterized by consciousness but some more so than others. Inert matter possesses only dim consciousness, and then with increased ability to think clearly come plants, animals, humans, and, finally, God. The goal of each monad is to think as clearly as it is capable of doing. Because humans share monads with matter, plants, and animals, sometimes our thoughts are less than clear.
