Primary qualities, secondary qualities and the truth about intention

In this paper I will argue that Crispin Wright’s defence of the claim that the truth about intention is judgement-dependent is unstable because it can serve also to establish that the truth about shape is judgement-dependent, thereby violating his constraint that in developing the distinction between judgement-independent and judgement-dependent subject matters we have to be driven by the assumption that colour and shape will fall on different sides of the divide.     

Making sense of powerful qualities

According to the powerful qualities view, properties are both powerful and qualitative. Indeed, on this view the powerfulness of a property is identical to its qualitativity. Proponents claim that this view provides an attractive alternative to both the view that properties are pure powers and the view that they are pure qualities. It remains unclear, however, whether the claimed identity between powerfulness and qualitativity can be made coherent in a way that allows the powerful qualities view to constitute this sort of alternative. I argue here that this can be done, given a particular conception of both the qualitativity and powerfulness of properties. On this conception, a property is qualitative just in the sense that its essence is fixed independently of any distinct properties, and it is powerful just if its essence grounds its dispositional role.

     

The acquisition of odour qualities

Odours can evoke a large range of qualities. Some of these qualities (e.g., sweetness) appear to be acquired through simultaneously experiencing odours mixed with tastes. Acquisition might also occur when two odours are experienced as a mixture. In this case mixture components might acquire each other's qualities. This was tested in two experiments. In the first, subjects repeatedly sniffed two odour mixtures (either AX, BY or AY, BX). Odours mixed with A acquired A's properties and were judged more similar to A than to B. Odours mixed with B were not clearly discriminable. The second experiment used a similar approach except that Odour B was replaced. Subjects now smelled either AX, CY or AY, CX. All components were discriminable. Odours mixed with A acquired A's properties and were judged more similar to A than to C. Although odours mixed with C did not acquire C's qualities due to a confusion of quality terms, odours previously mixed with C were judged as more similar to C than to A. Evidence of other quality exchanges were also obtained. These results suggest that pure odour qualities can be learnt and lend support to William James's (1890) notion of the acquired equivalence/distinctiveness of cues.     

Philosophical pictures and secondary qualities

The paper presents a novel account of nature and genesis of some philosophical problems, which vindicates a new approach to an arguably central and extensive class of such problems: The paper develops the Wittgensteinian notion of ‘philosophical pictures’ with the help of some notions adapted from metaphor research in cognitive linguistics and from work on unintentional analogical reasoning in cognitive psychology. The paper shows that adherence to such pictures systematically leads to the formulation of unwarranted claims, ill-motivated problems, and pointless theories. To do so, the paper proceeds from a case-study on a lastingly influential development in early modern philosophy: the adoption of the doctrine of secondary qualities, and its principal consequences. The findings motivate a new approach to an arguably extensive and important class of philosophical problems: to the problems we raise in the grip of philosophical pictures.     

Adult helping qualities preferred by adolescents

Most studies of therapeutic alliance have focused on adult populations and been written from the therapist's perspective. Thus, there is a clear need for studies of therapeutic alliance that focus on adolescent populations from the perspective of the adolescents. The current study is an exploratory process investigation using a focus group methodology with a nonclinical sample of adolescents to determine which traits in adults might foster alliance, with the assumption that the same traits would apply to therapeutic settings. A content analytic approach was used and 12 adult qualities found to be preferred by adolescents from most to least cited were: respect, time shared, openness, role characteristics, recognition, guidance, identification, trust, freedom, like/ dislike, responsibility, and familiarity.     

Common sense about qualities and senses

There has been some recent optimism that addressing the question of how we distinguish sensory modalities will help us consider whether there are limits on a scientific understanding of perceptual states. For example, Block has suggested that the way we distinguish sensory modalities indicates that perceptual states have qualia which at least resist scientific characterization. At another extreme, Keeley argues that our common-sense way of distinguishing the senses in terms of qualitative properties is misguided, and offers a scientific eliminativism about common-sense modalities which avoids appeal to qualitative properties altogether. I’ll argue contrary to Keeley that qualitative properties are necessary for distinguishing senses, and contrary to Block that our common-sense distinction doesn’t indicate that perceptual states have qualia. A non-qualitative characterization of perceptual states isn’t needed to avoid the potential limit on scientific understanding imposed by qualia.

Bradley-Terry-Luce scale of taste qualities of champagne]

In a paired comparison experiment 783 subjects judged five different brands of champagne (three normal and two alcohol-reduced). Each subject judged only one single pair with respect to which one tasted more fizzy ("spritziger"), dry ("trockener"), prickling ("prickelnder") and better ("besser"). Three extended versions of the Bradley-Terry-Luce model are discussed and used to assess scale values for the criteria as well as for order effects. The results can be summarized into three points: (1) Goodness-of-fit for the simple BTL-model is satisfactory for all criteria--except for the judgement "tastes better than". (2) Using four graded response categories instead of dichotomous responses decreases goodness-of-fit considerably. (3) Alcohol-reduced brands are less "dry", but are quite within the range of the other brands with respect to the remaining criteria. It is argued that the particular scaling method used is especially useful for deciding which criteria are appropriate for measurement on a one-dimensional scale and which are not.
