The Metaphysics of Social Kinds: Construction and Reality
Quick fact
In 2014, the Scottish Independence referendum saw citizens on both sides using 'Scottishness' as a social kind that felt deeply real, even though its legal definition had shifted over centuries.
Why this is interesting
Money, borders, and weekends feel as real as mountains or electricity—yet they only exist because we collectively agree they do. How do such intangible inventions become so solid?

Understanding The Metaphysics of Social Kinds: Construction and Reality
Think of social kinds as shared imagination made concrete. A piece of paper is just fiber and ink until everyone agrees it has value—then it becomes a banknote. This agreement is what philosophers call 'collective intentionality.' Unlike ice melting or planets orbiting, social kinds are not discovered in nature; they are created through our thoughts, language, and practices. They are like rules of a game: the rule that a bishop moves diagonally exists only because players accept the game. Similarly, social kinds exist because we accept the roles and statuses we assign to things and people. So, social reality is built from 'status functions'—we impose functions like 'money' or 'citizen' onto objects and people, and because we all cooperate, these functions become real in their effects.
A deeper explanation
The mechanism behind social kinds is the looping between individual intentions and collective acceptance. Philosopher John Searle distinguishes 'brute facts' (which exist independently of us, like mountains) from 'institutional facts' (which exist only within human institutions). Institutional facts are created by 'constitutive rules' of the form 'X counts as Y in context C.' For example, a particular piece of paper (X) counts as a twenty-dollar bill (Y) in the United States (C). The reality of social kinds is thus anchored in brute facts (the paper) but actualized by collective recognition. This recognition is not static; it can be challenged and changed. Understanding this reveals that social kinds are real in their consequences—they shape laws, economies, and identities—yet they are contingent on human agreement. Recognizing their constructed nature empowers us to critically examine and potentially reconstruct the social world.
