I formulate a counterfactual version of the notorious ‘Ramsey Test’. Whereas the Ramsey Test for indicative conditionals links credence in indicatives to conditional credences, the counterfactual version links credence in counterfactuals to expected conditional chance. I outline two forms: a Ramsey Identity on which the probability of the conditional should be identical to the corresponding conditional probability/expectation of chance; and a Ramsey Bound on which credence in the conditional should never exceed the latter. Even in the weaker, bound, form, the (...) counterfactual Ramsey Test makes counterfactuals subject to the very argument that Lewis used to argue against the indicative version of the Ramsey Test. I compare the assumptions needed to run each, pointing to assumptions about the time‐evolution of chances that can replace the appeal to Bayesian assumptions about credence update in motivating the assumptions of the argument. I finish by outlining two reactions to the discussion: to indicativize the debate on counterfactuals; or to counterfactualize the debate on indicatives. (shrink)

Let us call the Dependency Theses (DT) the view, first stated by Kant, that certain versions of the cosmological argument depend on the ontological argument. At least two different reasons have been given for the supposed dependence. Given the DT, some of Aquinas' views about God's essence, and about our knowledge of God's existence, can seem, at least at first, to be inconsistent. I consider two different ways of defending Aquinas against this suspicion of inconsistency. On the first defence, based (...) on a widespread understanding of his notion of 'necessary being', Aquinas' views fall outside the scope of the DT. The success of this defence is doubtful. There is, however, another defence to be found in Aquinas' work, one directed not to avoiding, but actually to rejecting, the DT. In this second defence, the DT is not a correct assessment even of those views that do fall within its scope. Its success means that Aquinas had available a principled refutation of the DT some five hundred years before it was first formulated. (shrink)

It is often said that the ontological argument fails because it wrongly treats existence as a first-level property or predicate. This has proved a controversial claim, and efforts to evaluate it are complicated by the fact that the words ‘existence is not a property/predicate’ have been used by philosophers to make at least three different negative claims: (a) one about a first-level phenomenon possessed by objects like horses, stones, you and me; (b) another about the logical form of assertions of (...) existence; and (c) still another about a second-level phenomenon possessed by concepts when they are instantiated. I argue that only the last of these claims, originally voiced by Kant, is both plausible and relevant to the ontological argument. And I try to show that the relevance of the Kantian version comes from its providing the underlying justification for a different, and far less controversial, criticism of the ontological argument. (shrink)

Kant gave a two-fold answer to the question, ‘Is existence a predicate?’. His view that existence is not a first-level predicate, i.e., a predicate of objects like horses, stones, and you and me, is widely known. What is not so well-known, however, is his claim that existence is a second-level predicate, a predicate of concepts or of a collection of predicates. In this paper I hope to show why his arguments for both claims are unsuccessful.

By whatever and by however many predicates we may think a thing – even if we completely determine it – we do not make the least addition to the thing when we further declare that this thing is. Otherwise, it would not be exactly the same thing that exists, but something more than we had thought in the concept; and we could not, therefore, say that the exact object of my concept exists.

This essay re-examines Meinong's "Über Gegenstandstheorie" and undertakes a clarification and revision of it that is faithful to Meinong, overcomes the various objections to his theory, and is capable of offering solutions to various problems in philosophy of mind and philosophy of language. I then turn to a discussion of a historically and technically interesting Russell-style paradox (now known as "Clark's Paradox") that arises in the modified theory. I also examine the alternative Meinong-inspired theories of Hector-Neri Castañeda and Terence Parsons.

Much work on mystical experience has taken for granted a certain view about the relation between experience and its interpretation. This ‘traditional view’ has received perhaps its most explicit statement in Stace's Mysticism and Philosophy . It is a view which is attractive to proponents of the doctrine of unanimity, the doctrine that at the phenomenological level all mystical experiences are basically similar. Recently, however, in a growing body of literature, the traditional view has come under heavy fire. Its critics (...) adopt a Kantian, indeed a hyper–Kantian, picture of experience. And they see the traditional view, accordingly, as ‘naïve’ and ‘simplistic’. In addition, hyper–Kantians typically reject the doctrine of unanimity. (shrink)

Frege argued that 1) in making existence assertions we ascribe (or deny) the second-Level property, 'not being empty', To a first-Level concept. He inferred from this that 2) existence is a second-Level property, The property 'not being empty'. He therefore rejected the ontological proof of the existence of God because, He claimed, It depends on the assumption that existence is a first-Level, And not a second-Level, Property. In this paper it is argued, First, That frege is unsuccessful in his attempt (...) to establish claim 1). Moreover, Claim 2) does not follow from claim 1)--One could accept claim 1) and still maintain that existence is a first-Level property. Thus, Even if the ontological proof does depend on the assumption that existence is a first-Level property, Frege's objection to that proof fails. (shrink)

In his long-awaited Mystic Union , Nelson Pike offers a phenomenology of mysticism. His account is based on the reports and descriptions of third parties, not on his own, first-person experience. So he calls his enterprise ‘phenomenography’, an attempt to describe the experiential content of conscious states by way of reports of them. Pike finds in the Christian mystical tradition three different kinds of experiences of mystic union, the ‘prayer of quiet’, the ‘prayer of union’ and ‘rapture’. These experiences differ (...) phenomenologically, i.e. in experiential content. But they are all ‘theistic’ experiences; that is, they are all phenomenologically of God. By this Pike means: whether these experiences are veridical or not, their object – what they are veridical or hallucinatory experiences of – is God; and that they are of God is part of, or given in, the phenomenological content of the experiences themselves.

A standard line in the contemporary philosophical literature has it that physical theories are equivalent only when they agree on their empirical content, where this empirical content is often understood as being encoded in the equations of motion of those theories. In this article, we question whether it is indeed the case that the empirical content of a theory is exhausted by its equations of motion, showing that (for example) considerations of boundary conditions play a key role in the empirical (...) equivalence (or otherwise) of theories. Having argued for this, we show that philosophical claims made by Weatherall (2016) that electromagnetism in the Faraday tensor formalism is equivalent to electromagnetism in the vector potential formalism, and by Knox (2011) that general relativity is equivalent to teleparallel gravity, can both be called into question. We then show that properly considering the role of boundary conditions in theory structure can potentially restore these claims of equivalence and close with some remarks on the pragmatics of adjudications on theory identity.

There are many branches of philosophy called “the philosophy of X,” where X = disciplines ranging from history to physics. The philosophy of artificial intelligence has a long history, and there are many courses and texts with that title. Surprisingly, the philosophy of computer science is not nearly as well-developed. This article proposes topics that might constitute the philosophy of computer science and describes a course covering those topics, along with suggested readings and assignments.

In this reply to James H. Fetzer’s “Minds and Machines: Limits to Simulations of Thought and Action”, I argue that computationalism should not be the view that (human) cognition is computation, but that it should be the view that cognition (simpliciter) is computable. It follows that computationalism can be true even if (human) cognition is not the result of computations in the brain. I also argue that, if semiotic systems are systems that interpret signs, then both humans and computers are (...) semiotic systems. Finally, I suggest that minds can be considered as virtual machines implemented in certain semiotic systems, primarily the brain, but also AI computers. In doing so, I take issue with Fetzer’s arguments to the contrary. (shrink)

This essay presents a philosophical and computational theory of the representation of de re, de dicto, nested, and quasi-indexical belief reports expressed in natural language. The propositional Semantic Network Processing System (SNePS) is used for representing and reasoning about these reports. In particular, quasi-indicators (indexical expressions occurring in intentional contexts and representing uses of indicators by another speaker) pose problems for natural-language representation and reasoning systems, because--unlike pure indicators--they cannot be replaced by coreferential NPs without changing the meaning of the (...) embedding sentence. Therefore, the referent of the quasi-indicator must be represented in such a way that no invalid coreferential claims are entailed. The importance of quasi-indicators is discussed, and it is shown that all four of the above categories of belief reports can be handled by a single representational technique using belief spaces containing intensional entities. Inference rules and belief-revision techniques for the system are also examined. (shrink)

This essay examines the role of non-existent objects in "epistemological ontology" — the study of the entities that make thinking possible. An earlier revision of Meinong's Theory of Objects is reviewed, Meinong's notions of Quasisein and Außersein are discussed, and a theory of Meinongian objects as "combinatorially possible" entities is presented.

A computer can come to understand natural language the same way Helen Keller did: by using “syntactic semantics”—a theory of how syntax can suffice for semantics, i.e., how semantics for natural language can be provided by means of computational symbol manipulation. This essay considers real-life approximations of Chinese Rooms, focusing on Helen Keller’s experiences growing up deaf and blind, locked in a sort of Chinese Room yet learning how to communicate with the outside world. Using the SNePS computational knowledge-representation system, (...) the essay analyzes Keller’s belief that learning that “everything has a name” was the key to her success, enabling her to “partition” her mental concepts into mental representations of: words, objects, and the naming relations between them. It next looks at Herbert Terrace’s theory of naming, which is akin to Keller’s, and which only humans are supposed to be capable of. The essay suggests that computers at least, and perhaps non-human primates, are also capable of this kind of naming. (shrink)

A critical study of John Searle's Minds, Brains and Science (Cambridge, MA: Harvard University Press, 1984).

This functional Magnetic Resonance Imaging study investigated high and low suggestible people responding to two visual hallucination suggestions with and without a hypnotic induction. Participants in the study were asked to see color while looking at a grey image, and to see shades of grey while looking at a color image. High suggestible participants reported successful alterations in color perception in both tasks, both in and out of hypnosis, and showed a small benefit if hypnosis was induced. Low suggestible people (...) could not perform the tasks successfully with or without the hypnotic induction. The fMRI results supported the self report data, and changes in brain activity were found in a number of visual areas. The results indicate that a hypnotic induction, although having the potential to enhance the ability of high suggestible people, is not necessary for the effective alteration of color perception by suggestion.
