Of the use of the moral argument

The limitation of Reason in respect of all our Ideas of the supersensible to the conditions of its practical employment has, as far as the Idea of God is concerned, undeniable uses. For it prevents Theology from rising into Theosophy (into transcendent concepts which confound Reason), or from sinking into Demonology (an anthropomorphic way of representing the highest Being). And it also prevents Religion from turning into Theurgy (a fanatical belief that we can have a feeling of other supersensible beings and can reciprocally influence them), or into Idolatry (a superstitious belief that we can please the Supreme Being by other means than by a moral sentiment).
