Through Ethics, The Buddha and Common Era

Besides the philosophy of religion, the problem of evil is important to the fields of theology and ethics. There are also discussions of evil in other philosophical fields, such as secular ethics and evolutionary ethics. However, the problem of evil is usually posed in a theological context.

Responses to the problem of evil have traditionally been in three types: refutations, defenses, and theodicies.

The problem of evil is generally formulated in two forms. The logical problem of evil tries to show a conceptual impossibility in the coexistence of a God and evil, while the evidential problem of evil tries to show that, given the existence of evil in the world, it is improbable that there is an omnipotent, omniscient, and a wholly good God.

Most philosophers see the logical problem of evil as having been rebutted by various defenses. The evidential arguments remain discussed among contemporary philosophers.

Definitions

Evil

In the context of the problem of evil, a broad concept of evil is typically used that encompasses "any bad state of affairs, wrongful action, or character flaw". These may be either natural evils or moral evils including minor harm or injustice, in contrast to the modern colloquial use of "evil" commonly associated with particularly horrendous moral acts. More restrictive definitions of evil are sometimes used in particular formulations and responses. Marcus Singer says that a usable definition of evil must be based on the knowledge that: "If something is really evil, it can't be necessary, and if it is really necessary, it can't be evil".

The concept of evil can take on different meanings when seen from the perspective of different belief systems. While evil can be viewed in religious terms, it can also be understood in natural or secular terms, such as social vice, egoism, criminality, and sociopathology. John Kekes writes that an action is evil if "(1) it causes grievous harm to (2) innocent victims, and it is (3) deliberate, (4) malevolently motivated, and (5) morally unjustifiable".

Omniqualities

Omniscience is the property of having complete or "maximal knowledge". Maximal is not necessarily unlimited, but limited to "God knowing what is knowable". This is the most widely accepted view of omniscience among scholars of the twenty-first century, and is what William Hasker calls freewill-theism. Within this view, future events that depend upon choices made by individuals with free will are unknowable until they occur.

Omnipotence is maximal power to bring about events within the limits of possibility, but again, maximal is not unlimited. According to the philosophers Hoffman and Rosenkrantz: "An omnipotent agent is not required to bring about an impossible state of affairs... maximal power has logical and temporal limitations, including the limitation that an omnipotent agent cannot bring about, i.e., cause, another agent's free decision".

Omnibenevolence sees God as all-good. If God is omnibenevolent, he acts according to what is best. If there is no best available, God attempts, if possible, to bring about states of affairs that are creatable and optimal within the limitations of physical reality.

Defenses and theodicies

Responses to the problem of evil have occasionally been classified as defences or theodicies, although authors disagree on the exact definitions. Generally, a defense refers to attempts to address the logical argument of evil that says "it is logically impossible – not just unlikely – that God exists". A defense does not require a full explanation of evil, and it need not be true, or even probable. It need only be possible, since possibility invalidates the logic of impossibility.

A theodicy, on the other hand, is more ambitious, since it attempts to provide a plausible justification – a morally or philosophically sufficient reason – for the existence of evil. This is intended to weaken the evidential argument which uses the reality of evil to argue that the existence of God is unlikely.
