12. Knowledge Sources / D. Empiricism / 1. Empiricism
Empiricism makes a basic distinction between truths based or not based on facts [Quine]
     Full Idea: One dogma of empiricism is that there is some fundamental cleavage between truths that are analytic, or grounded in meanings independently of facts, and truths which are synthetic, or grounded in fact.
     From: Willard Quine (Two Dogmas of Empiricism [1953], p.20)
Quine's empiricism is based on whole theoretical systems, not on single mental events [Quine, by Orenstein]
     Full Idea: Traditional empiricism takes impressions, ideas or sense data as the basic unit of empirical thought, but Quine takes account of the theoretical as well as the observational; the unit of empirical significance is whole systems of belief.
     From: report of Willard Quine (works [1961]) by Alex Orenstein - W.V. Quine Ch.1
     A reaction: This invites either the question of what components make up the whole systems, or (alternatively) what sort of mental events decide to accept a system as a whole. Should Quine revert either to traditional empiricism, or to rationalism?
Empiricism improvements: words for ideas, then sentences, then systems, then no analytic, then naturalism [Quine]
     Full Idea: Since 1750 empiricism shows five turns for the better. First was a shift from ideas to words. Second a shift from terms to sentences. Third the shift to systems of sentences. Fourth the abandonment of analytic-synthetic dualism. Fifth was naturalism.
     From: Willard Quine (Five Milestones of Empiricism [1975], p.67)
     A reaction: [compressed] Quine must be largely credited with the last two. The first four are almost entirely linguistic in character, which is characteristic of mid-twentieth-century empiricism. I would offer the recognition of explanation as central for the sixth.
Our outer beliefs must match experience, and our inner ones must be simple [Quine]
     Full Idea: The outer edge of our empirical system must be kept squared with experience; the rest, with all its elaborate myths and fictions, has as its objective the simplicity of laws.
     From: Willard Quine (Two Dogmas of Empiricism [1953], p.45)
In scientific theories sentences are too brief to be independent vehicles of empirical meaning [Quine]
     Full Idea: We have come to recognise that in a scientific theory even a whole sentence is ordinarily too short a text to serve as an independent vehicle of empirical meaning.
     From: Willard Quine (Five Milestones of Empiricism [1975], p.70)
12. Knowledge Sources / D. Empiricism / 4. Pro-Empiricism
Empiricism says evidence rests on the senses, but that insight is derived from science [Quine]
     Full Idea: The crucial insight of empiricism is that any evidence for science has its end points in the senses. This insight remains valid, but it is an insight which comes after physics, physiology, and psychology, not before.
     From: Willard Quine (On Mental Entities [1952], p.225)
     A reaction: Interesting. I think Hume and co. were probably outlining essential presuppositions and contraints which must be accepted by science. Quine offers empiricism as more like a description of science (with success as its authority?).
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
The second dogma is linking every statement to some determinate observations [Quine, by Yablo]
     Full Idea: Quine's second dogma of empiricism is the reductionism that finds every statement to be linkable by fixed correspondence rules to a determinate range of confirming observations.
     From: report of Willard Quine (Two Dogmas of Empiricism [1953]) by Stephen Yablo - Does Ontology Rest on a Mistake? V
     A reaction: Quine's response to this is to embrace holism about theories, instead of precise connections with Humean impressions. I'm thinking that Lewis disagrees with Quine, when his Humean supervenience rests on a 'mosaic' of small qualities.
Senses cannot judge one another, so what judges senses cannot be a sense, but must be superior [Cudworth]
     Full Idea: The sight cannot judge of sounds, nor the hearing of light and colours; wherefore that which judges of all the senses and their several objects, cannot be itself any sense, but something of a superior nature.
     From: Ralph Cudworth (On Eternal and Immutable Morality [1688], Ch.II.VI.1)
     A reaction: How nice to find a seventeenth century English writer rebelling against empiricism!
