Free will is the notional capacity or ability to choose between different possible courses of action unimpeded.
Determinism is the philosophical view that events are completely determined by previously existing causes. Deterministic theories throughout the history of philosophy have developed from diverse and sometimes overlapping motives and considerations. Like eternalism, determinism focuses on particular events rather than the future as a concept. The opposite of determinism is indeterminism, or the view that events are not deterministically caused but rather occur due to chance. Determinism is often contrasted with free will, although some philosophers claim that the two are compatible.
Incompatibilism is the view that a deterministic universe is completely at odds with the notion that persons have free will, the latter being defined as the capacity of conscious agents to choose a future course of action among several available physical alternatives. Thus, incompatibilism implies that there is a dichotomy between determinism and free will, where philosophers must support at most one or the other, not both. The incompatibilist view is pursued further in at least three different ways: libertarians deny that the universe is deterministic, hard determinists deny that any free will exists, and pessimistic incompatibilists deny both that the universe is determined and that free will exists.
Compatibilism is the belief that free will and determinism are mutually compatible and that it is possible to believe in both without being logically inconsistent.
Indeterminism is the idea that events are not caused, or are not caused deterministically.
Libertarianism is one of the main philosophical positions related to the problems of free will and determinism which are part of the larger domain of metaphysics. In particular, libertarianism is an incompatibilist position which argues that free will is logically incompatible with a deterministic universe. Libertarianism states that since agents have free will, determinism must be false and vice versa.
Hard determinism is a view on free will which holds that determinism is true, that it is incompatible with free will, and therefore that free will does not exist. Although hard determinism generally refers to nomological determinism, it can also be a position taken with respect to other forms of determinism that necessitate the future in its entirety.

Moral agency is an individual's ability to make moral choices based on some notion of right and wrong and to be held accountable for these actions. A moral agent is "a being who is capable of acting with reference to right and wrong."
Beyond Freedom and Dignity is a 1971 book by American psychologist B. F. Skinner. Skinner argues that entrenched belief in free will and the moral autonomy of the individual hinders the prospect of using scientific methods to modify behavior for the purpose of building a happier and better-organized society.
Harry Gordon Frankfurt was an American philosopher. He was a professor emeritus of philosophy at Princeton University, where he taught from 1990 until 2002. Frankfurt also taught at Yale University, Rockefeller University, and Ohio State University.
Prevenient grace is a Christian theological concept that refers to the grace of God in a person's life which precedes and prepares to conversion. The concept was first developed by Augustine of Hippo (354–430), was affirmed by the Second Council of Orange (529) and has become part of Catholic theology. It is also present in Reformed theology, through the form of an effectual calling leading some individuals irresistibly to salvation. It is also in Arminian theology, according to which it is dispensed universally in order to enable people to respond to the offer of salvation, though it does not ensure personal acceptance.
Moral luck describes circumstances whereby a moral agent is assigned moral blame or praise for an action or its consequences, even if it is clear that said agent did not have full control over either the action or its consequences. This term, introduced by Bernard Williams, has been developed, along with its significance to a coherent moral theory, by Williams and Thomas Nagel in their respective essays on the subject.
In philosophy, moral responsibility is the status of morally deserving praise, blame, reward, or punishment for an act or omission in accordance with one's moral obligations. Deciding what counts as "morally obligatory" is a principal concern of ethics.
Frankfurt cases were presented by philosopher Harry Frankfurt in 1969 as counterexamples to the principle of alternate possibilities (PAP), which holds that an agent is morally responsible for an action only if that person could have done otherwise.
R. Jay Wallace is a Professor of Philosophy and Judy Chandler Webb Distinguished Chair for Innovative Teaching and Research at the University of California, Berkeley. His areas of specialization include moral philosophy and philosophy of action. He is most noted for his work on practical reason, moral psychology, and meta-ethics.
Free will in antiquity is a philosophical and theological concept. Free will in antiquity was not discussed in the same terms as used in the modern free will debates, but historians of the problem have speculated who exactly was first to take positions as determinist, libertarian, and compatibilist in antiquity. There is wide agreement that these views were essentially fully formed over 2000 years ago. Candidates for the first thinkers to form these views, as well as the idea of a non-physical "agent-causal" libertarianism, include Democritus, Aristotle, Epicurus, Chrysippus, and Carneades.
The Augustinian theodicy, named for the 4th- and 5th-century theologian and philosopher Augustine of Hippo, is a type of Christian theodicy that developed in response to the evidential problem of evil. As such, it attempts to explain the probability of an omnipotent (all-powerful) and omnibenevolent (all-loving) God amid evidence of evil in the world. A number of variations of this kind of theodicy have been proposed throughout history; their similarities were first described by the 20th-century philosopher John Hick, who classified them as "Augustinian". They typically assert that God is perfectly (ideally) good, that he created the world out of nothing, and that evil is the result of humanity's original sin. The entry of evil into the world is generally explained as consequence of original sin and its continued presence due to humans' misuse of free will and concupiscence. God's goodness and benevolence, according to the Augustinian theodicy, remain perfect and without responsibility for evil or suffering.
Agent causation, or Agent causality, is an idea in philosophy which states that a being who is not an event—namely an agent—can cause events. Agent causation contrasts with event causation, which occurs when an event causes another event. Whether agent causation as a concept is logically sound is itself a topic of philosophical debate.
Abilities are powers an agent has to perform various actions. They include common abilities, like walking, and rare abilities, like performing a double backflip. Abilities are intelligent powers: they are guided by the person's intention and executing them successfully results in an action, which is not true for all types of powers. They are closely related to but not identical with various other concepts, such as disposition, know-how, aptitude, talent, potential, and skill.
