Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

The special issue, “Psychiatry and Its Philosophy,” focuses on addressing the mindbrain dualism and connected problems in the clinical and scientific contexts of psychiatry. Authors in this special issue address the theoretical disagreements that are manifest in the clinical and scientific goals of psychiatry and explore the possibility of reconciling the claim that research on psychopathology needs to be scientific with the claim that it needs to address the needs of patients in the clinic. Our approach is forward looking and concerned with drawing on ideas and methods from the philosophy of science and philosophy of mind to promote pluralism in psychiatry.

Is behavioral integration a necessary feature of belief in folk psychology? Our data from over 5,000 people across 26 samples, spanning 22 countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we argue that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely asserts that p, nonlinguistic behavioral evidence is disregarded. In light of this, we take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology.

The title and blurb suggest that this book makes a case for eliminating concepts. The suggestion is misleading, however. What Machery really does is multiply them.Here is his characterization of what concepts are. He says that a concept is ‘a body of knowledge about x that is stored in long-term memory and that is used by default in the processes underlying most, if not all, higher cognitive competences when these processes result in judgements about x’. He holds that people represent categories through exemplars, prototypes and theories, that these types of representations really exist, and that they all count as concepts according to the above characterization.Machery offers an interesting new take on the concept research undertaken by cognitive psychologists over the past three or four decades. Psychology textbooks tend to classify the main theories of concepts as follows. They draw a contrast between the ‘classical definition’ theory and late 20th century ‘probabilistic’ theories. They distinguish, within the probabilistic camp, between ‘prototype-based’ theories and ‘exemplar-based’ theories, and they admit a further family of ‘theory–theories’, according to which a concept of x is a mini-theory about x. Within each camp, different specific …

Is behavioral integration (i.e., which occurs when a subjects assertion that p matches her non-verbal behavior) a necessary feature of belief in folk psychology? Our data from nearly 6,000 people across twenty-six samples, spanning twenty-two countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we suggest that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely asserts that p, non-linguistic behavioral evidence is disregarded. In light of this, we take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology.

There are two primary traditions in philosophical theorizing about moral standing—one emphasizing Experience (the capacity to feel pain and pleasure) and one emphasizing Agency (complexity of cognition and lifestyle). In this article we offer an explanation for this divide: Lay judgments about moral standing depend importantly on two independent cues (Experience and Agency), and the two philosophical traditions reflect this aspect of folk moral cognition. In support of this two-source hypothesis, we present the results of a series of new experiments providing evidence for our account of lay judgments about moral standing, and argue that these results lend plausibility to the proposed causal link between folk moral cognition and the philosophical traditions.

Although cognitive scientists have learned a lot about concepts, their findings have yet to be organized in a coherent theoretical framework. In addition, after twenty years of controversy, there is little sign that philosophers and psychologists are converging toward an agreement about the very nature of concepts.Doing without Concepts(Machery 2009) attempts to remedy this state of affairs. In this article, I review the main points and arguments developed at greater length inDoing without Concepts.

At the end of a chapter in his book Race, Racism and Reparations, Angelo Corlett notes that “[t]here remain other queries about racism [than those he addressed in his chapter], which need philosophical exploration. … Perhaps most important, how might racism be unlearned?” (2003, 93). We agree with Corlett’s assessment of its importance, but find that philosophers have not been very keen to directly engage with the issue of how to best deal with, and ultimately do away with, racism. Rather, they have tended to make cursory remarks about the issue at the end of papers devoted to defining “racism” or attempting to capture the essence of racism itself. In this article, we put the issue of how to best deal with racism front and center. We need not start from scratch, however. Despite not being central to many philosophical discussions about race, a number of different strategies for dealing with racism have been suggested. To that end, we have identified three of the most concrete proposals made by philosophers and social theorists, each of which seeks to mitigate racism by inducing psychological changes in individuals.2 For each, we formulate the..
