WITTGENSTEIN AND DEFINING CRITERIA

Let us introduce two antithetical terms in order to avoid certain elementary confusions: To the question “How do you know that so-and-so is the case?”, we sometimes answer by giving ‘criteria’ and sometimes by giving ‘symptoms. If medical science calls angina an inflammation caused by a particular bacillus, and we ask in a particular case “Why do you say this man has got angina?” then the answer “I have found the bacillus so-and-so in his blood” gives us the criterion, or what we may call the defining criterion of angina. If on the other hand the answer was, “His throat is inflamed”, this might give us a symptom of angina, I call “sympton” a phenomenon of which experience has taught us that it coincided, in some way or other, with the phenomenon which is our defining criterion, Then to say “A man has angina if this bacillus is found in him” is a tautology or it is a loose way of stating the definition of “angina”. But to say, “A man has angina whenever he has an inflamed throat” is to make a hypothesis. (BB, pp. 24–25)¹     

What Is Music? Is There a Definitive Answer?

Philosophers frequently defend definitions by appealing to intuitions and contemporary folk classificatory norms. I raise methodological concerns that undermine some of these defenses. Focusing on Andrew Kania's recent definition of music, I argue that the way in which it has been developed leads to problems, and I show that a number of other definitions of interest to philosophers of art (and others) run into similar problems.     

Relational mechanisms in the goal pursuit process

Four studies tested a model for goal pursuit, which proposed three relational mechanisms that yield motives for a goal. These motives, in turn, predict goal outcomes, but the association was expected to be stronger among women than among men. Study 1 (n = 116) tested the model for a short‐term, collaborative project between strangers; Study 2 (n = 186) examined parents being motivated by their children to be healthier; Study 3 (n = 124) examined nontraditional college students' career searches; and Study 4 (n = 181) examined young adults' progress toward a self‐improvement goal. Results showed support for the model in all four studies, with the exception that feeling accountable to others was not a consistent predictor of relational motives.     

The Problem of Free Mass: Must Properties Cluster?

Properties come in clusters. It seems impossible, for instance, that a mass could float free, unattached to any other property. David Armstrong takes this as a reductio of the bundle theory and an argument for substrata, while Peter Simons and Arda Denkel reply by supplementing the bundle theory with accounts of property interdependencies. I argue against both views. Virtually all plausible ontologies turn out to be committed to the existence of free masses. I develop and defend the view that the clustering of properties is a mere contingent truth, on grounds that properties can be subtracted one-by-one. This opens the door not just to the (unsupplemented) bundle theory, but also to any plausible account of the relation between objects and properties.
