what is the problem of individuation?
Adjuntos: individuation – Lukasiewicz.pdf
The problem of individuation asks: what makes an individual thing the distinct, unified entity that it is?
More precisely, it has two main aspects, which Popper helpfully distinguishes in the document:
The first problem (Lukasiewicz’s): What makes a composite thing — something with many parts — a unity rather than merely a collection? Socrates is made of flesh, bones, atoms, and these change throughout his life, yet he remains one Socrates from birth to death. What accounts for that wholeness?
The second problem (Anscombe’s): What distinguishes two individuals that might be qualitatively identical — the same shape, size, composition? Two bronze balls might be indistinguishable in every property, yet they are clearly two, not one. Wherein lies their difference?
The classical Aristotelian framing, which the symposium takes as its starting point, poses it as: since every individual consists of matter (hylē) and form (eidos), which of these is responsible for individuality?
Underlying all three is the deeper puzzle of why we cannot fully define an individual using only universal properties — any definition by qualities alone captures a kind, never a unique individual.
