(Greek: pan, all; theos, god)
The opinion that everything is divine, that the world is an emanation or part of the essence of God.
This is the way that one who believes in God states the opinion, but the pantheist believes that matter and its energies are God, in reality not having a proper conception of God at all.
It is a more common opinion than people generally imagine.
Insistence on the right of private judgment in matters of religion naturally creates a self-conceit which leads one to feel above the lot of human nature and in some manner equal to the Being on Whose revelation one passes judgment.
