The article presents the main logical and metaphysical assumptions of Bolzano's theodicy. The conception of truths in themselves is understood as a logical assumption of Bolzano's proposal, and the conception of substance is the metaphysical assumption of the theodicy in question. The world, according to Bolzano, is causally determined and it is also logically determined to the effect that the world is a model of a system of truths in themselves. Truths in themselves are independent of God (the nature of relation between God and truth is explained in the article), and hence God is not responsible for evil in the world.
