2. Reason / D. Definition / 2. Aims of Definition
A simplification which is complete constitutes a definition [Kant]
     Full Idea: By dissection I can make the concept distinct only by making the marks it contains clear. That is what analysis does. If this analysis is complete ...and in addition there are not so many marks, then it is precise and so constitutes a definition.
     From: Immanuel Kant (Wiener Logik [1795], p.455), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap 1 'Conc'
     A reaction: I think Aristotle would approve of this. We need to grasp that a philosophical definition is quite different from a lexicographical definition. 'Completeness' may involve quite a lot.
5. Theory of Logic / A. Overview of Logic / 3. Value of Logic
Logic gives us the necessary rules which show us how we ought to think [Kant]
     Full Idea: In logic the question is not one of contingent but of necessary rules, not how to think, but how we ought to think.
     From: Immanuel Kant (Wiener Logik [1795], p.16), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 02 'Trans'
     A reaction: Presumably it aspires to the objectivity of a single correct account of how we all ought to think. I'm sympathetic to that, rather than modern cultural relativism about reason. Logic is rooted in nature, not in arbitrary convention.
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
No one has defended translational phenomenalism since Ayer in 1940 [Ayer, by Kim]
     Full Idea: I know of no serious defence of 'translational phenomenalism' since Ayer's in 1940.
     From: report of A.J. Ayer (The Foundations of Empirical Knowledge [1940]) by Jaegwon Kim - What is 'naturalized epistemology'? 303-4+n
     A reaction: We can think of Ayer as a hero who explored how far extreme empiricism would go. We still have anti-realists who are singing from a revised version of the song-sheet. Personally I am with Russell, that we must embrace the best explanation.
12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
We are not conscious of pure liquidity, but of the liquidity of water [Firth]
     Full Idea: We are not conscious of liquidity, coldness, and solidity, but of the liquidity of water, the coldness of ice, and the solidity of rocks.
     From: Roderick Firth (Sense Data and the Percept Theory [1949]), quoted by Howard Robinson - Perception 1.7
     A reaction: A nice point, but it might not be entirely true in a blindfold test, where one might only report properties like 'sticky' or 'warm', without having any clear concept of the substance being experienced. Firth is proposing the 'percept theory'.
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / b. Pro-externalism
If we knew what we know, we would be astonished [Kant]
     Full Idea: If we only know what we know ...we would be astonished by the treasures contained in our knowledge.
     From: Immanuel Kant (Wiener Logik [1795], p.843), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap 1 'Conc'
     A reaction: Nice remark. He doesn't require immediat recall of knowledge. You can't be required to know that you know something. That doesn't imply externalism, though. I believe in securely founded internal knowledge which is hard to recall.
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
The attribution of necessity to causation is either primitive animism, or confusion with logical necessity [Ayer]
     Full Idea: How are we to explain the word 'must' [about causation]? The answer is, I think, that it is either a relic of animism, or else reveals an inclination to treat causal connexion as if it were a form of logical necessity.
     From: A.J. Ayer (The Foundations of Empirical Knowledge [1940], IV.18)
     A reaction: The animism proposal just about makes sense (as a primitive feature of minds), but why would anyone, if they had the time and understanding, dream of treating a regular connection as a 'logical' necessity?
