This document discusses different philosophical perspectives on the concept of evil. It begins by outlining the deductive argument from evil, which argues that the existence of evil is logically incompatible with the existence of an omnipotent, omniscient, and perfectly good God. It then examines various theories that have attempted to resolve this incompatibility, such as the idea that some evils may be logically necessary for greater goods. The document also analyzes different formulations of the problem of evil, like axiological and deontological approaches. Finally, it explores specific theories of evil proposed by philosophers and thinkers like Kant, Arendt, and various dualist and privation theories.
