What the thing is
Essentialism is the view that objects have attributes necessary to their identity.
Where it came from
It originated in early Western thought—with Plato’s forms and Aristotle’s substance—in the Parmenides dialogue and Categories.
What it gets right
It captures real cognitive patterns: humans do group things by perceived core features. It grounded pre-Darwinian biology and formal logic.
What it gets wrong
It reifies social identities as natural kinds. It treats contingent historical categories—like race or gender—as fixed, intrinsic, and necessary.
Why it matters now
It underpins contested claims in machine learning, gender theory, and race science—where ‘essences’ are still invoked without scrutiny.
Is it worth your time
Yes—if you care how categories shape power, identity, and classification in science, law, or AI.
