5. Theory of Logic / J. Model Theory in Logic / 2. Isomorphisms

14212	A consistent theory just needs one model; isomorphic versions will do too, and large domains provide those [Lewis]
	Full Idea: A consistent theory is, by definition, one satisfied by some model; an isomorphic image of a model satisfies the same theories as the original model; to provide the making of an isomorphic image of any given model, a domain need only be large enough.
	From: David Lewis (Putnam's Paradox [1984], 'Why Model')
	A reaction: This is laying out the ground for Putnam's model theory argument in favour of anti-realism. If you are chasing the one true model of reality, then formal model theory doesn't seem to offer much encouragement.

7. Existence / D. Theories of Reality / 4. Anti-realism

14213	Anti-realists see the world as imaginary, or lacking joints, or beyond reference, or beyond truth [Lewis]
	Full Idea: Anti-realists say the only world is imaginary, or only has the parts or classes or relations we divide it into, or doubt that reference to the world is possible, or doubt that our interpretations can achieve truth.
	From: David Lewis (Putnam's Paradox [1984], 'Why Anti-R')
	A reaction: [compression of a paragraph on anti-realism] Lewis is a thoroughgoing realist. A nice example of the rhetorical device of ridiculing an opponent by suggesting that they don't even know what they themselves believe.

9. Objects / C. Structure of Objects / 8. Parts of Objects / b. Sums of parts

14210	A gerrymandered mereological sum can be a mess, but still have natural joints [Lewis]
	Full Idea: The mereological sum of the coffee in my cup, the ink in this sentence, a nearby sparrow, and my left shoe is a miscellaneous mess of an object, yet its boundaries are by no means unrelated to the joints of nature.
	From: David Lewis (Putnam's Paradox [1984], 'What Might')
	A reaction: In that case they do, but if there are no atoms at the root of physics then presumably their could also be thoroughly jointless assemblages, involving probability distributions etc. Even random scattered atoms seem rather short of joints.

14. Science / C. Induction / 1. Induction

22200	If you eliminate the impossible, the truth will remain, even if it is weird [Conan Doyle]
	Full Idea: When you have eliminated the impossible, whatever remains, however improbable, must be the truth.
	From: Arthur Conan Doyle (The Sign of Four [1890], Ch. 6)
	A reaction: A beautiful statement, by Sherlock Holmes, of Eliminative Induction. It is obviously not true, of course. Many options may still face you after you have eliminated what is actually impossible.

16. Persons / E. Rejecting the Self / 4. Denial of the Self

5517	Individuals don't exist, but are conventional names for sets of elements [Buddha]
	Full Idea: There exists no individual, it is only a conventional name given to a set of elements.
	From: Buddha (Siddhartha Gautama) (reports [c.540 BCE]), quoted by Derek Parfit - The Unimportance of Identity p.295
	A reaction: I take this to arise from an excessively spiritual concept of a human being, which faces Descartes' problem of how to individuate non-physical minds, when they have no clear boundaries. Combine dualism with a bundle theory, and you have Buddhism.

19. Language / B. Reference / 3. Direct Reference / b. Causal reference

14215	Causal theories of reference make errors in reference easy [Lewis]
	Full Idea: Whatever happens in special cases, causal theories usually make it easy to be wrong about the thing we refer to.
	From: David Lewis (Putnam's Paradox [1984], 'What Is')
	A reaction: I suppose the point of this is that there are no checks and balances to keep reference in focus, but just a requirement to keep connected to an increasingly attenuated causal chain.

19. Language / B. Reference / 4. Descriptive Reference / b. Reference by description

14209	Descriptive theories remain part of the theory of reference (with seven mild modifications) [Lewis]
	Full Idea: Description theories of reference are supposed to have been well and truly refuted. I think not: ..it is still tenable with my seven points, and part of the truth of reference [7: rigidity, egocentric, tokens, causal, imperfect, indeterminate, families].
	From: David Lewis (Putnam's Paradox [1984], 'Glob Desc')
	A reaction: (The bit at the end refers to his seven points, on p.59). He calls his basic proposal 'causal descriptivism', incorporating his seven slight modifications of traditional descriptivism about reference.

29. Religion / C. Spiritual Disciplines / 3. Buddhism

7600	The Buddha believed the gods would eventually disappear, and Nirvana was much higher [Buddha, by Armstrong,K]
	Full Idea: The Buddha believed implicitly in the gods because they were part of his cultural baggage, but they were involved in the cycle of rebirth, and would eventually disappear; the ultimate reality of Nirvana was higher than the gods.
	From: report of Buddha (Siddhartha Gautama) (reports [c.540 BCE]) by Karen Armstrong - A History of God Ch.1
	A reaction: We might connect this with Plato's Euthyphro question (Ideas 336 and 337), and the relationship between piety and morality on the one hand, and the gods on the other.

7601	Life is suffering, from which only compassion, gentleness, truth and sobriety can save us [Buddha]
	Full Idea: Buddha taught that the only release from 'dukkha' (the meaningless flux of suffering which is human life) is a life of compassion for all living beings, speaking and behaving gently, kindly and accurately, and refraining from all intoxicants.
	From: Buddha (Siddhartha Gautama) (reports [c.540 BCE], Ch.1), quoted by Karen Armstrong - A History of God Ch.1
	A reaction: Christians are inclined to give the impression that Jesus invented the idea of being nice, but it ain't so. The obvious thought is that the Buddha seems to be focusing on the individual, but this is actually a formula for a better community.
