Gene-Culture Coevolution (GCC) theory is an intriguing new entry in the quest to understand human culture. Nonetheless, it has received relatively little philosophical attention. One notable exception is Kim Sterelny’s (2006) critique which raises three primary objections against the GCC account. Most importantly, he argues that GCC theory, as it stands, is unable to resolve “the paradox of cultural accumulation” (151); that while social learning should generally be prohibitively expensive for the pupils, it nonetheless occurs as the principle means of disseminating novel information through a culture. Sterelny holds that this is best explained by supplementing the GCC models with strong cultural group selection pressures. I argue that this is not needed. To show this I elaborate upon Joseph Henrich and Francisco Gil-White’s (2001) information goods theory, developing it in terms of the market pressures that one would expect to find in an information economy. I indicate how such pressures contribute to an individual-level explanation of cultural accumulation that answers Sterelny’s concerns.

In recent years, developments in experimental philosophy have led many thinkers to reconsider their central assumptions and methods. It is not enough to speculate and introspect from the armchair - philosophers must subject their claims to scientific scrutiny, looking at evidence and in some cases conducting new empirical research. "The Theory and Practice of Experimental Philosophy" is an introduction and guide to the systematic collection and analysis of empirical data in academic philosophy. This book serves two purposes: first, it examines the theory behind “x-phi,” including its underlying motivations and the objections that have been leveled against it. Second, the book offers a practical guide for those interested in doing experimental philosophy, detailing how to design, implement, and analyze empirical studies. Thus, the book explains the reasoning behind x-phi and provides tools to help readers become experimental philosophers.

A standard methodology in philosophy of language is to use intuitions as evidence. Machery, Mallon, Nichols, and Stich challenged this methodology with respect to theories of reference by presenting empirical evidence that intuitions about one prominent example from the literature on the reference of proper names vary between Westerners and East Asians. In response, Sytsma and Livengood conducted experiments to show that the questions Machery and colleagues asked participants in their study were ambiguous, and that this ambiguity affected the responses given by Westerners. Sytsma and Livengood took their results to cast doubt on the claim that the current evidence indicates that there is cross-cultural variation in intuitions about the Gödel case. In this paper we report on a new cross-cultural study showing that variation in intuitions remains even after controlling for the ambiguity noted by Sytsma and Livengood

It is not uncommon to find assumptions being made about folk psychology in the discussions of phenomenal consciousness in philosophy of mind. In this article I consider one example, focusing on what Dan Dennett says about the 'folk theory of consciousness'. I show that he holds that the folk believe that qualities like colours that we are acquainted with in ordinary perception are phenomenal qualities. Nonetheless, the shape of the folk theory is an empirical matter and in the absence of empirical investigation there is ample room for doubt. Fortunately, experimental evidence on the topic is now being produced by experimental philosophers and psychologists. This article contributes to this growing literature, presenting the results of six new studies on the folk view of colours and pains. I argue that the results indicate against Dennett's theory of the folk theory of consciousness

In this essay, we discuss how Descartes arrives at his mature view of material causation. Descartes’ position changes over time in some very radical ways. The last section spells out his final position as to how causation works in the world of material objects. When considering Descartes’ causal theories, it is useful to distinguish between ‘vertical’ and ‘horizontal’ causation. The vertical perspective addresses God’s relation to creation. God is essential being, and every being other than God depends upon God in order to exist and to continue in existence.Thus, from the vertical perspective, the act of creating and fact of coming into existence are co-extensive notions. This metaphysical/theological framework is the basis of Descartes’ commitment to three interrelated notions: that genuine causes and effects occur simultaneously; that causing is appropriately the case only when the cause is acting; and the view that God is the efficient, total, and continuous cause of everything that exists and every action that occurs. So from the vertical perspective, things are nothing without God’s continuous creation, and there is a problem in articulating how they are said to have independent being and causal efficacy. It is in terms of these commitments that Descartes’ views on horizontal, or material, causation must be approached. We will make apparent the radical extent to which his account of intra-worldly causation abandons his earlier and more traditional views about material causation. To this end we discuss Descartes’ journey to his mature position by emphasizing the growing epistemic limitations of his philosophy, which culminate in what we call his epistemic stance.

Do philosophers and ordinary people conceive of subjective experience in the same way? In this article, we argue that they do not and that the philosophical concept of phenomenal consciousness does not coincide with the folk conception. We first offer experimental support for the hypothesis that philosophers and ordinary people conceive of subjective experience in markedly different ways. We then explore experimentally the folk conception, proposing that for the folk, subjective experience is closely linked to valence. We conclude by considering the implications of our findings for a central issue in the philosophy of mind, the hard problem of consciousness.

In this article I critique Kathleen Slaney and Michael Maraun’s (2005) addition to the ongoing philosophical charge that neuroscientific writing often transgresses the bounds of sense. While they sometimes suggest a minimal, cautious thesis–that certain usage can generate confusion and in some cases has–they also bandy about charges of meaninglessness, conceptual confusion, and nonsense freely. These charges rest on the premise that terms have specific correct usages that correspond with Slaney and Maraun’s sense of everyday linguistic practice. I challenge this premise. I argue that they have not shown that there are such specific correct usages; and, further, that even if they had, they fail to justify that their definitions are the correct ones.

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.
