What is philosophical intention?

If you blink involuntarily, it is a physiological reflex; if you wink at a friend, it is a social communication. Physically, the movements may be identical, yet one is a mere event while the other is an **intentional action**. Philosophical intention is the "aboutness" or "directedness" that transforms blind physical movement into meaningful human conduct. ## The Two Faces of Intention In philosophy, "intention" occupies two distinct but overlapping domains: **Intentionality** (the property of mental states) and **Intention-in-action** (the teleological structure of doing). ### 1. Intentionality: The Mark of the Mental First formalized in the modern era by [Franz Brentano](https://plato.stanford.edu/entries/brentano/) in his 1874 work, *Psychology from an Empirical Standpoint*, intentionality is the mind's capacity to represent or be "about" things. Brentano argued that this is the defining characteristic that separates the mental from the physical. > "Every mental phenomenon is characterized by what the Scholastics of the Middle Ages called the intentional (or mental) inexistence of an object, and what we might call, though not wholly unambiguously, reference to a content, direction toward an object." — Franz Brentano, *Psychology from an Empirical Standpoint*. Crucially, intentionality allows us to think about things that do not exist, such as a golden mountain or a round square—a feat no purely physical system, like a rock or a river, can achieve. ### 2. Intention: The Logic of "Why?" While Brentano focused on the mind's direction, [G.E.M. Anscombe](https://en.wikipedia.org/wiki/G._E._M._Anscombe) revolutionized the field in her 1957 monograph, [*Intention*](https://academic.oup.com/book/35165). Anscombe argued that we identify intentional actions not by looking "inward" at a private mental state, but by the application of a specific sense of the question **"Why?"** If someone asks "Why are you doing that?" and the answer provides a reason (e.g., "to make tea") rather than a cause (e.g., "because my nerves fired"), the action is intentional. Anscombe’s brilliance was in showing that we have "knowledge without observation" of our own intentional actions; you don't need to look at your legs to know you are walking to the store. ## The Causal Theory of Action Modern debates often center on [Donald Davidson’s](https://plato.stanford.edu/entries/action/) "Actions, Reasons, and Causes" (1963). Davidson argued that an intention is a "pro-attitude" combined with a belief that acts as the **rational cause** of an action. This bridged the gap between abstract reasons and the physical world, suggesting that intentions are not just descriptions, but forces that move the body. ## Provocative Follow-up Questions 1. **The Problem of Deviant Causal Chains:** If I intend to spill my drink to distract someone, but I get so nervous that my hand shakes and spills the drink "accidentally," did I act intentionally? 2. **Collective Intentionality:** Can a group, such as a corporation or a nation, have an "intention" that is distinct from the intentions of its individual members? (See: [John Searle on Social Reality](https://plato.stanford.edu/entries/intentionality/)). 3. **Artificial Agency:** If an AI can provide a "Why?" for its outputs that satisfies Anscombe's criteria, does it possess genuine philosophical intention, or is it merely simulating the "mark of the mental"?
