Despite their centrality to medicine, drugs are not easily defined. We introduce two desiderata for a basic definition of medical drugs. It should: (a) capture everything considered to be a drug in medical contexts and (b) rule out anything that is not considered to be a drug. After canvassing a range of options, we find that no single definition of drugs can satisfy both desiderata. We conclude with three responses to our exploration of the drug concept: maintain a monistic concept, (...) or choose one of two pluralistic outcomes. Notably, the distinction between drugs and other substances is placed under pressure by the most plausible of the options available. (shrink)

Recently, there is a renewed debate concerning the role of perspective in vision. Morales et al. (2020) present evidence that, in the case of viewing a rotated coin, the visual system is sensitive to what has often been called “perspectival shapes.” It has generated vigorous discussions, including an online symposium by Morales and Cohen, an exchange between Linton (2021) and Morales et al. (2021), and most recently, a fierce critique by Burge and Burge (2022), in which they launch various (...) conceptual and empirical objections. Although Morales and Firestone (2022) have responded to them recently, and we are in agreement with Morales and Firestone in general, there are further problems in Burge and Burge (2022) that are worth highlighting. The main point of this comment is that what the Burge–Burge team call “viewpoint-dependent relational properties” are simply instances of what the Morales–Firestone team call “perspectival shapes”; the confusion arises from Burge and Burge’s misconstrual of Morales et al.’s claims. This shows that conceptually, the two teams are in large agreement, as Morales and Firestone (2022) also point out, and the focus should be put on the empirical disagreements, which has been covered by Morales and Firestone (2022). Relatedly, we argue that Burge and Burge (2022) misinterpret Morales et al. (2020) as supporting a new entity in perception science, and that this misinterpretation is a primary source of their apparent disagreement. This is worth pointing out because such misunderstanding generates many unnecessary quarrels that hinder progress. (shrink)

The importance of contextual reasoning is emphasized by various researchers in AI. (A partial list includes John McCarthy and his group, R. V. Guha, Yoav Shoham, Giuseppe Attardi and Maria Simi, and Fausto Giunchiglia and his group.) Here, we survey the problem of formalizing context and explore what is needed for an acceptable account of this abstract notion.

Other people figure in our experience of the world; they strike us as unique and gen- uinely other. This paper explores whether a Husserlian account of empathy as the way in which we constitute an intersubjective world can account for the uniqueness and otherness of other people in our experience. I contend that it can’t. I begin by explicating Husserl’s theory of empathy, paying particular attention to the reduction to a purely egoic sphere and the steps that ostensibly permit a (...) subject to re-inhabit a world of others from out of this sphere. In querying Husserl’s theory, I consider a series of problems, raised by Zhida Luo, concerning the apparent centrality of bod- ily similarity in empathy. I sketch Luo’s solution, which involves a shift to tactile similarity. While it makes for a better theory of empathy, this solution isn’t sufficient to make room for the givenness of another person not originally predicated on simi- larity. To clarify what’s at issue here, I turn to the Husserlian pictures of empathy presented by Heinz Kohut and Edith Stein. I conclude with a remark about what might be required, given the inability of Husserlian empathy to make room for the experience of others as singular and other, for a picture of our phenomenal life to have a shape that accounts for the coexistence of empathy to others who are like oneself and hospitality to others as genuine others.
