13. Knowledge Criteria / E. Relativism / 2. Knowledge as Convention
By nature people are close to one another, but culture drives them apart [Hippias]
     Full Idea: I regard you all as relatives - by nature, not by convention. By nature like is akin to like, but convention is a tyrant over humankind and often constrains people to act contrary to nature.
     From: Hippias (fragments/reports [c.430 BCE]), quoted by Plato - Protagoras 337c8
18. Thought / C. Content / 11. Teleological Semantics
Biosemantics says content is useful mapping from a producer to a consumer system [Millikan, by Schulte]
     Full Idea: Millikan's 'biosemantic' view is that representations stand midway between producer and consumer systems. The represented states of affairs (the content) maps onto the second system, and thus enable its proper function.
     From: report of Ruth Garrett Millikan (Varieties of Meaning [2002]) by Peter Schulte - Mental Content 4.4
     A reaction: These meets my standard objection to all functional theories (e.g. of mind), that observing relations and functions tells you nothing about what it actually is. Millikan seems to explain the role of content, but says nothing about its actual nature.
18. Thought / E. Abstraction / 7. Abstracta by Equivalence
An 'abstraction principle' says two things are identical if they are 'equivalent' in some respect [Boolos]
     Full Idea: Hume's Principle has a structure Boolos calls an 'abstraction principle'. Within the scope of two universal quantifiers, a biconditional connects an identity between two things and an equivalence relation. It says we don't care about other differences.
     From: George Boolos (Is Hume's Principle analytic? [1997]), quoted by Michèle Friend - Introducing the Philosophy of Mathematics 3.7
     A reaction: This seems to be the traditional principle of abstraction by ignoring some properties, but dressed up in the clothes of formal logic. Frege tries to eliminate psychology, but Boolos implies that what we 'care about' is relevant.
