Deism. System of those who, rejecting all revelation, believe only in the existence of God. Certain commentators confound Deism with Theism, seeking to designate thereby only the common foundation of all the philosophical doctrines which profess the belief in a God. But in the general acceptation, the Deist is the one who affects to limit his belief to the faith in a rational, impersonal God, whose attributes and providence he does not seek to determine. For him, God is only the first cause, the great indispensable mechanism of the world's movement. Deism does not push its inquiries any farther, and for the most of its followers the immortality of the soul as well as the divine personality are insoluble problems, about which the human mind should not concern itself.
