Viewpoints on Concepts

Compare Plato’s Forms with Popper’s World 3—using selected passages from “Epistemology Without a Knowing Subject” in Objective Knowledge—by distinguishing their contents, dependence on human minds, capacity to change, and role in explaining objective knowledge.

Describe Rosch's prototype theory as empirical evidence for graded membership and typicality effects in human categorization.

Relate prototype theory and family resemblance to concepts in machine learning, such as cluster centroids and vector space embeddings (e.g., word2vec).

Distinguish natural kinds (e.g., 'water') from social or functional kinds (e.g., 'game') and explain why this distinction is critical to the debate.

Evaluate whether the two views can be reconciled by applying classical theory to natural kinds and family resemblance to social/functional kinds.

Assess whether 'fuzzy' concepts are irreducibly fuzzy or are always decomposable into combinations of precise concepts, formulating your own position.
