Thus faith is a kind of attitude of trust or assent.
As such, it is ordinarily understood to involve an act of will or a commitment on the part of the believer.
Religious faith involves a belief that makes some kind of either an implicit or explicit reference to a transcendent source.
(Theism: Longer definition) Theism states that the existence and continuance of the universe is owed to one supreme Being, who is distinct from Creation.
For this reason, theism proclaims a dualistic relation between God and the world, wherein God is a being who controls events from outside of the human world.
Immanuel Kant (1724-1804) focused on elements of the philosophy of religion for about half a century─from the mid-1750s, when he started teaching philosophy, until after his retirement from academia.
