One neat thing Feuerbach said:
Hegel said "Man is God self-alienated" -- Feuerbach reversed this to say that "God is Man self-alienated." This more or less means that God is all the ideals Man could not achieve projected onto something until it turned into its own thing. For Feuerbach, this is a bad thing. He thought that as long as we humans continued to alienate ourselves toward some God, we could not achieve our own being.
Parts of some of this are from 'Looking at Philosophy' by Donald Palmer
