5. Theory of Logic / F. Referring in Logic / 1. Naming / b. Names as descriptive
We don't normally think of names as having senses (e.g. we don't give definitions of them) [Searle]
     Full Idea: If Tully=Cicero is synthetic, the names must have different senses, which seems implausible, for we don't normally think of proper names as having senses in the way that predicates do (we do not, e.g., give definitions of proper names).
     From: John Searle (Proper Names [1958], p.89)
     A reaction: It is probably necessary to prize apart the question of whether Tully 'has' (intrinsically) a sense, from whether we think of Tully in that way. Stacks of books have appeared about this one, since Kripke.
How can a proper name be correlated with its object if it hasn't got a sense? [Searle]
     Full Idea: It seems that a proper name could not have a reference unless it did have a sense, for how, unless the name has a sense, is it to be correlated with the object?
     From: John Searle (Proper Names [1958], p.91)
     A reaction: This might (just) be the most important question ever asked in modern philosophy, since it provoked Kripke into answering it, by giving a social, causal, externalist account of how names (and hence lots of language) actually work. But Searle has a point.
'Aristotle' means more than just 'an object that was christened "Aristotle"' [Searle]
     Full Idea: Aristotle being identical with an object that was originally christened will not suffice, for the force of "Aristotle" is greater than the force of 'identical with an object named "Aristotle"', for not just any object named "Aristotle" will do.
     From: John Searle (Proper Names [1958], p.93)
     A reaction: This anticipates Kripke's proposal to base reference on baptism. I remain unsure about how rigid a designation of Aristotle could be, in a possible world where his father died young, and he became an illiterate soldier who hates philosophy.
Reference for proper names presupposes a set of uniquely referring descriptions [Searle]
     Full Idea: To use a proper name referringly is to presuppose the truth of certain uniquely referring descriptive statements. ...Names are pegs on which to hang descriptions.
     From: John Searle (Proper Names [1958], p.94)
     A reaction: This 'cluster' view of Searle's has become notorious, but I think one could at least try to mount a defence. The objection to Searle is that none of the descriptions are necessary, unlike just being the named object.
Proper names are logically connected with their characteristics, in a loose way [Searle]
     Full Idea: If asked whether or not proper names are logically connected with characteristics of the object to which they refer, the answer is 'yes, in a loose sort of way'.
     From: John Searle (Proper Names [1958], p.96)
     A reaction: It seems to be inviting trouble to assert that a connection is both 'logical' and 'loose'. Clearly Searle has been reading too much later Wittgenstein. This is probably the weakest point in Searle's proposal, which brought a landslide of criticism.
14. Science / C. Induction / 3. Limits of Induction
Maybe induction is only reliable IF reality is stable [Mitchell,A]
     Full Idea: Maybe we should say that IF regularities are stable, only then is induction a reliable procedure.
     From: Alistair Mitchell (talk [2006]), quoted by PG - Db (ideas)
     A reaction: This seems to me a very good proposal. In a wildly unpredictable reality, it is hard to see how anyone could learn from experience, or do any reasoning about the future. Natural stability is the axiom on which induction is built.
26. Natural Theory / C. Causation / 4. Naturalised causation
Physical causation consists in transference of conserved quantities [Dowe, by Mumford/Anjum]
     Full Idea: For Dowe physical causation consists in transference of conserved quantities.
     From: report of Phil Dowe (Physical Causation [2000]) by S.Mumford/R.Lill Anjum - Getting Causes from Powers 10.2
     A reaction: [see Psillos 2002 on this] This is evidently a modification of the idea of physical causation as energy-transfer, but narrowing it down to exclude trivial cases. I guess. Need better physics.
Causation interaction is an exchange of conserved quantities, such as mass, energy or charge [Dowe, by Psillos]
     Full Idea: Dowe argues that a 'causal process' is a world line of an object with a conserved quantity (such as mass, energy, momentum, charge), and a 'causal interaction' is an exchange between two such objects.
     From: report of Phil Dowe (Physical Causation [2000]) by Stathis Psillos - Causation and Explanation §4.4
     A reaction: This looks very promising. Nice distinction between causal process and causal interaction. 'Conserved quantities' is better physics than just 'energy'. We can hand causation over to the scientist?
26. Natural Theory / D. Laws of Nature / 9. Counterfactual Claims
Dowe commends the Conserved Quantity theory as it avoids mention of counterfactuals [Dowe, by Psillos]
     Full Idea: Dowe commends the Conserved Quantity theory because it avoids any mention of counterfactuals.
     From: report of Phil Dowe (Physical Causation [2000]) by Stathis Psillos - Causation and Explanation §4.4
     A reaction: Clearly the truth of a counterfactual is quite a problem for an empiricist/scientist, but one needs to distinguish between reality and our grasp of it. We commit ourselves to counterfactuals, even if causation is transfer of conserved quantities.
