Love - Hate

Empedocles explained motion by assuming the principles of Love and Hate. Love combines the elements into things and Hate explains their dissolution. But if love and Hate are not the fifth and sixth elements, what are they? Apparently Empedocles was embarrassed. The earlier hylozoism had not seemed to need any additional moving principle because matter itself is alive or spontaneous; but when Empedocles was forced to reject his philosophy, he was in fact straining after the distinction between animate and inanimate. And it is not surprising that this first attempt lacked precision. Cited from S. Mulholland, The Beginnings
