8 ideas

5. Theory of Logic / C. Ontology of Logic / 4. Logic by Convention

12394	If the result is bad, we change the rule; if we like the rule, we reject the result [Goodman]
	Full Idea: A rule is amended if it yields an inference we are unwilling to accept; an inference is rejected if it violates a rule we are unwilling to amend.
	From: Nelson Goodman (Fact, Fiction and Forecast (4th ed) [1954], p.64)
	A reaction: This is clearly in tune with Quine's assertion that logic is potentially revisable, and the idea is pragmatist in spirit. It is hard to deny that intuitions about what makes a good argument control our logic. I say the world controls our intuitions.

8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions

14292	Dispositions seem more ethereal than behaviour; a non-occult account of them would be nice [Goodman]
	Full Idea: Dispositions of a thing are as important to us as overt behaviour, but they strike us by comparison as rather ethereal. So we are moved to enquire whether we can bring them down to earth, and explain disposition terms without reference to occult powers.
	From: Nelson Goodman (Fact, Fiction and Forecast (4th ed) [1954], II.3)
	A reaction: Mumford quotes this at the start of his book on dispositions, as his agenda. I suspect that the 'occult' aspect crept in because dispositions were based on powers, and the dominant view was that these were the immediate work of God.

9. Objects / C. Structure of Objects / 2. Hylomorphism / a. Hylomorphism

16620	A chair is wood, and its shape is the form; it isn't 'compounded' of the matter and form [Hobbes]
	Full Idea: Nothing can be compounded of matter and form. The matter of a chair is wood; the form is the figure it has, apt for the intended use. Does his Lordship think the chair compounded of the wood and the figure?
	From: Thomas Hobbes (Letter to Bramhall [1650], 4:302), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 07.1
	A reaction: Aristotle does use the word 'shape' [morphe] when he is discussing hylomorphism, and the statue example seems to support it, but elsewhere the form is a much deeper principle of individuation.

9. Objects / D. Essence of Objects / 15. Against Essentialism

16622	Essence is just an artificial word from logic, giving a way of thinking about substances [Hobbes]
	Full Idea: Essence and all other abstract names are words artificial belonging to the art of logic, and signify only the manner how we consider the substance itself.
	From: Thomas Hobbes (Letter to Bramhall [1650], 4:308), quoted by Robert Pasnau - Metaphysical Themes 1274-1671
	A reaction: I sympathise quite a lot with this view, but not with its dismissive tone. The key question I take to be: if you reject essences entirely (having read too much physics), how are we going to think about entities in the world in future?

11. Knowledge Aims / C. Knowing Reality / 3. Idealism / d. Absolute idealism

21971	Transcendental philosophy is the subject becoming the originator of unified reality [Kant]
	Full Idea: Transcendental philosophy is the act of consciousness whereby the subject becomes the originator of itself and, thereby, of the whole object of technical-practical and moral-practical reason in one system - ordering all things in God
	From: Immanuel Kant (Posthumous notes [1799], 21:78, p.245), quoted by A.W. Moore - The Evolution of Modern Metaphysics 06 App
	A reaction: This is evidently Kant's last word on the matter (c.1799), and Moore says he was drifting close to Fichte's idealism, in which reality is actually (sort of) created by our own minds. Disappointing! God's role here is unclear.

14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem

18749	Goodman argued that the confirmation relation can never be formalised [Goodman, by Horsten/Pettigrew]
	Full Idea: Goodman constructed arguments that purported to show that a satisfactory syntactic analysis of the confirmation relation can never be found. In response, philosophers of science tried to model it in probabilistic terms.
	From: report of Nelson Goodman (Fact, Fiction and Forecast (4th ed) [1954]) by Horsten,L/Pettigrew,R - Mathematical Methods in Philosophy 4
	A reaction: I take this idea to say that Bayesianism was developed in response to the grue problem. This is an interesting light on 'grue', which never bothered me much. The point is it scuppered formal attempts to model induction.

17646	Goodman showed that every sound inductive argument has an unsound one of the same form [Goodman, by Putnam]
	Full Idea: Goodman has shown that no purely formal criterion can distinguish arguments that are intuitively sound inductive arguments for unsound ones: for every sound one there is an unsound one of the same form. The predicates in the argument make the difference.
	From: report of Nelson Goodman (Fact, Fiction and Forecast (4th ed) [1954]) by Hilary Putnam - Why there isn't a ready-made world 'Causation'
	A reaction: This is to swallow grue whole. I think a bit more chewing is called for. By this date Putnam strikes me as a crazy relativist who has lost his grip on the world. Note the word 'formal' - but Putnam seems to think the argument is important.

26. Natural Theory / D. Laws of Nature / 3. Laws and Generalities

4794	We don't use laws to make predictions, we call things laws if we make predictions with them [Goodman]
	Full Idea: Rather than a sentence being used for prediction because it is a law, it is called a law because it is used for prediction.
	From: Nelson Goodman (Fact, Fiction and Forecast (4th ed) [1954], p.21), quoted by Stathis Psillos - Causation and Explanation §5.4
	A reaction: This smacks of dodgy pragmatism, and sounds deeply wrong. The perception of a law has to be prior to making the prediction. Why do we make the prediction, if we haven't spotted a law. Goodman is mesmerised by language instead of reality.
