During the balmy days when it was socially acceptable to entertain logical positivism as a coherent philosophical position, it was commonly thought that questions of metaphysics were senseless, nonsense, or not even wrong. There are, of course, no shortage of problems with positivism and it’s safe to say that positivism is one of the very few philosophical theses that attained the distinction of being rejected because it was, in fact, actually wrong. However, granting all of that, it is no less the case that contemporary ontology has been shaped largely by a debate which took place on positivist grounds: the debate between Carnap and Quine on metaontology. The simple version of their respective positions might be boiled down to two ideas: for Carnap, metaphysical or ontological questions don’t really have an answer, while for Quine they do, and for Carnap, there are two kinds of truth, while for Quine ‘truth is truth’ and comes in only one variety. The outcome of this debate would have far-reaching consequences for metaphysics and ontology. Continue reading
Jaegwon Kim, in his superb essay The nonreductivists troubles with mental causation (from the volume Supervenience and Mind), argues that nonreductive materialism (NRM) and emergentism (E) have the same cash value. He identifies four key theses that NRM is committed to: (1) all concrete particulars are physical (2) mental properties are not reducible to physical properties (3) all mental properties are physically realized and (4) mental properties are real properties of objects and events. Kim finds that E is committed to the same four theses: E accepts a materialist ontology (1), accepts that emergent properties are not reducible to their ‘basal conditions’ (2), accepts that higher-level or emergent properties need a physical base; this physical base is itself sufficient for the emergence of these properties (3) and finally, E accepts realism about the mental (4). These agreements are sufficient to show that NRM and E are, more or less, the same thing. Thus, any problems had by one are had by the other. Should NRM face an insurmountable difficulty, E will as well, and should E face its own insurmountable difficulty, then NRM also will. Continue reading
In Destiny and Deliberation, Johnathan Kvanvig mounts an impressive attack on universalism on two fronts: the goodness of God and the freedom of man, and, to this reader at any rate, has given more than ample reason to doubt the truth of universalism. Perhaps what makes this so persuasive to me is that the arguments are purely philosophical – no retreat to contentious translations or traditions are possible here, no invoking of controversial thinkers to place universalism on firmer ground. If these arguments work, universalism is simply not an option. Kvanvig is working with what he calls ‘McTaggert’s dilemma‘, but I actually think that if we bracket that to the side, the challenge to universalism is even starker. The arguments proceed roughly as follows. The truth of universalism is either contingent or necessary – i.e., universalism is a possibility or it’s an impossibility. The former attacks the goodness of God, and the latter attacks the freedom of man.
Roger Scruton, in his Gifford Lectures entitled The Face of God, argues that human beings cannot be understood properly if they are not conceived as subjects in a world of objects. What I want to do here is to argue along those same lines, but flesh out what exactly is entailed in subjecthood. Subjecthood, I maintain, consists primarily in rational freedom. This defintion brings together the classical definition of person as an individual substance of a rational nature together with the more modern definition of a person wherein the fundamental human property consists in the freedom of self-determination.

In Saving Belief, Lynne Rudder-Baker takes to task one of the two central doctrines within reductionist/eliminativist (RE) philosophies of mind: the doctrine of folk-psychology as an empirical theory. This doctrine, put simply, states that what traditional philosophers take to be the very ‘stuff’ of the mind – propositional attitudes, for example – is a kind of empirical theory and framework used in every-day, common-sense interaction and prediction of behaviour. Paul Churchland defines it thus: Continue reading
Naturalizing intentionality is easy. We could go Searle’s route, and argue for a causal, but not ontological, reduction of intentionality and intentional states, as well as their emergence from brain processes. Intentionality here would be inseparable from consciousness, and would be a way of representing the world so we can act on it. Keeping with Searle, an arrangement of particles by an agent would be an example of derived intentionality, the same kind of intentionality that language has. Continue reading
If you ask the average man on the street what a law of nature is, chances are you’re going to get a reply that’s not too dissimilar from what Nancy Cartwright calls the ‘facticity’ view – ‘the view that laws of nature describe facts about reality.’ (Do the Laws of Physics State the Facts?) Cartwright describes this view as so deeply ingrained into the (presumably human) psyche that it doesn’t even have a name. It is simply The View. Comparing the laws of physics with biological laws, Cartwright notes: Continue reading
