Etchemendy on Squeezing Arguments and Logical Consequence: a Reply to Griffiths

Owen Griffiths has recently argued that Etchemendy’s account of logical consequence faces a dilemma. Etchemendy claims that we can be sure that his account does not overgenerate, but that we should expect it to undergenerate. Griffiths argues that if we define the relationship between formal and natural language as being dependent on logical consequence, then Etchemendy’s claims are not true; and if we define the relationship as being independent of logical consequence, then we cannot assess the truth of the claims without further information. I argue that Griffiths misconstrues Etchemendy’s theory and overstates the first horn of the dilemma: Etchemendy does see the relationship as being dependent on logical consequence, but that does not mean that his claims are not true.     

Plural Action Sentences and Logical Form: Reply to Himmelreich

This paper replies to Himmelreich's ‘The Paraphrase Argument Against Collective Actions’ [2017], which presents three putative counterexamples to the multiple agents analysis of plural action sentences. The paper shows that the argument from the first example, the discursive dilemma, fails because it relies crucially on a simplification of the target analysis, and that the others don't bear on the question because they turn out on examination to be about individual rather than group action sentences.     

Logical Properties of Warrant

Trenton Merricks argues that on any reasonable account, warrant must entailtruth. I demonstrate three theses about the properties ofwarrant: (1) Warrant is not unique;there are many properties that satisfy the definition of warrant. (2) Warrant need not entail truth; there are some warrant properties that entailtruthand others that do not. (3) Warrant need not be closed under entailment, even if knowledge is. If knowledge satisfies closure, then some warrant properties satisfy closure while others do not;if knowledge violates closure, then allwarrant properties violate closure.

Reply to Krellenstein on Parallel Computation

I recently argued that the position in the philosophy of mind called functionalism is undermined by the importance of recent work on parallel computation (Thagard, 1986). In reply, Krellenstein (1987) contends that parallelism does not have the philosophical significance I claimed for it. Although his contentions are plausible if one focuses on what is in principle computationally possible, they fail if one looks at real problems.     

Reply to Noordhof on Mental Causation

In my paper 'The Properties of Mental Causation', PQ , 47 (1997), pp. 178–94. I proposed (as others have) a trope-based solution to a problem of mental causation. Noordhof in PQ , 48 (1998), pp. 221–6, has objected that the solution raises new problems just as intractable as the original. Some of his criticisms are based on misunderstandings of the role of tropes in the theory and of my general aim. He does, however, usefully develop an objection I addressed briefly in my paper: even if the trope solution explains how mental properties are causally relevant, does it explain how they are relevant qua mental? That is, does the problem appear again at the level of tropes? This kind of objection can be raised against any proposed solution to the problem, but it depends on the questionable assumption that properties themselves have properties. Noordhof also insists that the trope solution must provide a criterion of trope identity, but this is, I argue, a red herring in this context.
