Give the defining characteristics of Kant's Two Worlds: the World of Nature and the World of Actions, Morals, and Faith.

The Word of Nature consists of physical objects which we perceive through the concepts of our understanding, constituted according to certain rules. This is a world of cause and effect relations; the world of science and technology, in which the self is an object to be known. In contrast, in the World of Actions, Morals, Faith, the self is an agent, free to choose its ends and carry out its intentions, guided by rational principles of morality and consciousness of duty to be done. This is the world in which we have a moral conception of God's necessary existence and know ourselves to be immortal souls.
