Philosophy of action in the context of G. E. M. Anscombe

In philosophy, practical reason is the use of reason to decide how to act. It contrasts with theoretical reason, often called speculative reason, the use of reason to decide what to believe. For example, agents use practical reason to decide whether to build a telescope, but theoretical reason to decide which of two theories of light and optics is the best.

Gertrude Elizabeth Margaret Anscombe FBA (/ˈænskəm/; 18 March 1919 – 5 January 2001), usually cited as G. E. M. Anscombe or Elizabeth Anscombe, was a British analytic philosopher. She wrote on the philosophy of mind, philosophy of action, philosophical logic, philosophy of language, and ethics. She was a prominent figure of analytical Thomism, a fellow of Somerville College, Oxford, and a professor of philosophy at the University of Cambridge.

Anscombe was a student of Ludwig Wittgenstein and became an authority on his work and edited and translated many books drawn from his writings, above all his Philosophical Investigations. Anscombe's 1958 article "Modern Moral Philosophy" introduced the term consequentialism into the language of analytic philosophy, and had a seminal influence on contemporary virtue ethics. Her monograph Intention (1957) was described by Donald Davidson as "the most important treatment of action since Aristotle". It is "widely considered a foundational text in contemporary philosophy of action" and has also had influence in the philosophy of practical reason."

Permission, in philosophy, is the attribute of a person whose performance of a specific action, otherwise ethically wrong or dubious, would thereby involve no ethical fault. The term "permission" is more commonly used to refer to consent. Consent is the legal embodiment of the concept, in which approval is given to another party.

Permissions depend on norms or institutions.
