Free will

Free will is generally understood as the capacity or ability of people to (a) choose between different possible courses of action, (b) exercise control over their actions in a way that is necessary for moral responsibility, or (c) be the ultimate source or originator of their actions. There are different theories as to its nature, and these aspects are often emphasized differently depending on philosophical tradition, with debates focusing on whether and how such freedom can coexist with physical determinism, divine foreknowledge, and other constraints.
