Social Philosophy

What it asks

A five-pound note is a piece of polymer that is also money. A building is a university. A pair of people are married. In each case the physical facts underdetermine the social facts completely, and the social facts are not thereby illusions - try withholding tax on the grounds that money is a collective fiction.

So the branch asks what social entities are, how collective acceptance can make something real, and what happens when the acceptance is unequal, unnoticed or coerced.

Its second question is about relations rather than entities. Power, recognition, solidarity, oppression and alienation are all ways people stand to one another, and all of them can hold without anyone intending them.

The recurring problems

How collective acceptance creates facts. Something counts as money because everyone treats it as money. Stating that without circularity, and explaining why some such facts are stable and others collapse, is the core of social ontology.

Individuals or structures. Whether all social facts reduce to facts about individuals, or whether structures explain things individuals cannot. The dispute is not merely methodological: it determines whether unjust outcomes require unjust individuals.

What power is. Power that operates by shaping what people want is invisible to any measure of whose preferences prevail, and it is arguably the most consequential kind. Measuring something defined by its invisibility is a genuine methodological problem.

Oppression without oppressors. Disadvantage can be produced by rules that no one designed for that purpose and that each participant follows innocently. Locating fault, or deciding it is the wrong category, is unresolved.

How it developed

Marx's account of alienation and of class made social relations rather than individual conduct the object of criticism, and set the template for everything critical in the field.

Durkheim insisted that social facts are external to individuals and constrain them, and are therefore a distinct subject matter rather than aggregate psychology.

Hegel's account of recognition - that a person becomes a self through being acknowledged by others - was recovered in the twentieth century and became one of the field's most productive ideas, reframing many struggles as demands for recognition rather than for resources.

The analytic strand arrived late. Searle's account in 1995 of how collective intentionality creates institutional facts gave the field a precise vocabulary, and work on collective intention and group agency has grown from it. Iris Marion Young's analysis of oppression as five distinct faces, in 1990, did the same on the critical side.

The positions within it

Methodological individualism and holism; critical theory; recognition theory; social constructionism; collective intentionality approaches to social ontology. All are in the Schools section.

Where it stands now

Social ontology is the growth area, and it has become technical: group agency, collective responsibility and the metaphysics of social kinds all now have substantial literatures.

That work matters beyond philosophy because corporations, states and institutions are treated as agents in law while it remains unclear what makes a group an agent at all - and because the question of whether a group can be responsible when no member is has stopped being hypothetical.
