In what sense Kant is considered as agnostic?

Immanuel Kant is often considered agnostic in the sense that he argued that human reason is limited in its ability to know the nature of the divine or the metaphysical realm. In his "Critique of Pure Reason," Kant posits that while we can have moral beliefs and practical reason that suggest the existence of God, we cannot attain certain knowledge about God's existence through pure reason or empirical observation. This position leads him to assert that while we can have faith, we cannot have definitive knowledge about metaphysical concepts like God, the soul, or the afterlife. Thus, Kant's philosophy embodies a form of agnosticism regarding ultimate questions of existence.
