Abstract: The discussion of the adaptive landscape in the philosophical literature appears to be divided along the following lines. On the one hand, some claim that the adaptive landscape is either ‘uninterpretable’ or incoherent. On the other hand, some argue that the adaptive landscape has been an important heuristic, or tool in the service of explaining, as well as proposing and testing hypotheses about evolutionary change. This paper attempts to reconcile these two views.
The Evolution of Vagueness
Abstract: Vague predicates, those that exhibit borderline cases, pose a persistent problem for philosophers and logicians. Although they are ubiquitous in natural language, when used in a logical context, vague predicates lead to contradiction. This paper will address a question that is intimately related to this problem. Given their inherent imprecision, why do vague predicates arise in the first place? I discuss a variation of the signaling game where the state space is treated as contiguous, i.e., endowed with a metric that captures a similarity relation over states. This added structure is manifested in payoffs that reward approximate coordination between sender and receiver as well as perfect coordination. I evolve these games using a variation of Herrnstein reinforcement learning that better reflects the generalizing learning strategies real-world actors use in situations where states of the world are similar. In these simulations, signaling can develop very quickly, and the signals are vague in much the way ordinary language predicates are vague – they each exclusively apply to certain items, but for some transition period both signals apply to varying degrees. Moreover, I show that under certain parameter values, in particular when state spaces are large and time is limited, learning generalization of this sort yields strategies with higher payoffs than standard Herrnstein reinforcement learning. These models may then help explain why the phenomenon of vagueness arises in natural language: the learning strategies that allow actors to quickly and effectively develop signaling conventions in contiguous state spaces make it unavoidable
How to Disagree Without Being Disagreeable
Abstract: It is tempting to assume that disagreements about the principles, policies and institutions that shape contemporary political life – especially the disagreements that emerge during contemporary political contests in the United States – are uniquely uncivil. But for much of human history, disagreement about such matters has often been a rough and tumble affair and the best evidence of this emerges in contests for political power. Unflattering epithets about political opponents can be found in hieroglyphics on the tombs of Egyptian pharaohs, and political insult and invective were common in political competitions in ancient Rome. Moreover, with the rise of the modern political campaign and increased sophistication and complexity in the means for transmitting and targeting campaign messages innuendo, rumor, and even outright character assassination, became familiar fixtures of political life.
Language, Thought, and Other Biological Categories
Publisher’s Note: Beginning with a general theory of function applied to body organs, behaviors, customs, and both inner and outer representations, Ruth Millikan argues that the intentionality of language can be described without reference to speaker intentions and that an understanding of the intentionality of thought can and should be divorced from the problem of understanding consciousness. The results support a realist theory of truth and of universals, and open the way for a nonfoundationalist and nonholistic approach to epistemology.
Including Trans Women in Sport: Analyzing Principles and Policies of Fairness in Competition
Abstract: In this paper, we examine the scientific, legal, and ethical foundations for inclusion of transgender women athletes in competitive sport, drawing on IOC principles and relevant Court of Arbitration for Sport decisions. We argue that the inclusion of transathletes in competition commensurate with their legal gender is the most consistent position with these principles of fair and equitable sport. Biological restrictions, such as endogenous testosterone limits, are not consistent with IOC and CAS principles. We explore the implications for recognizing that endogenous testosterone values are a natural physical trait and that excluding legally recognized women for high endogenous testosterone values constitutes discrimination on the basis of a natural physical trait. We suggest that the justificatory burden for such prima facie discrimination is unlikely to be met. Thus, in place of a limit on endogenous testosterone for women (whether cisgender, transgender, or intersex), we argue that legally recognized gender is most fully in line with IOC and CAS principles.
Kant and the Capacity to Judge: Sensibility and Discursivity in the Transcendental Analytic of the “Critique of Pure Reason”
Publisher’s Note: “Kant and the Capacity to Judge” will prove to be an important and influential event in Kant studies and in philosophy.
Welfare and Harm After Death
Abstract: My aim in this essay is to defend the claim that posthumous harm is possible against an argument that assumes that an event harms a person only if it makes it the case that his or her welfare diminishes (compared to some benchmark) and further assumes that no one exists after death. This argument gets a purchase against posthumous harm only if one adds what I call Mortality-Bounded Welfare: the thesis that no events that occur after the end of one-s life can detrimentally affect one-s welfare. I accept the first two assumptions with some modification, but provide an argument to reject Mortality-Bounded Welfare. Although I use an argument form familiar in these kinds of discussions — contrast cases in a thought-experiment, one involving an undeniably living person, and one not — my defense of the thesis that the boundaries of welfare-affecting events may extend beyond the existence of the person in question is novel. My strategy is to make a case for a human condition having residual boundaries, by which I mean that it may obtain because of events that postdate a person, and then argue that it affects welfare. In the course of my argument, I provide a subsidiary argument that rights have residual boundaries. In particular, I argue that once rights vest (in existing people), they delineate not only a sphere of behavior that satisfies the rights but also a sphere of rights-violating behavior on the part of others. Unless this delineation is defeated by moral means, actual behavior on the part of others that falls within the respective spheres is right-satisfying or right-violating. The story does not change with regard to a right to performances potentially or necessarily postdating the right-holder.
Unlike some attempts to argue that posthumous harm is possible, my defense of the possibility of posthumous harm is compatible with various metaphysical positions about when a posthumous harm occurs.
I go on to demonstrate that my thought-experiment argument is free of an important objection (raised by Taylor, 2005) to two well-known attempts to defend posthumous harm on the basis of thought-experiments, Parfit-s (1984) and Feinberg-s (1984).
For the sake of completeness, I sketch a different thought-experiment argument against Mortality-Bounded Welfare. I explain why this different thought-experiment does not make use of the idea of rights with residual boundaries.
In closing, I trace a recent attempt, grounded in our agency, to argue for the possibility of posthumous harm. This attempt accepts, as mine does, the assumptions about welfare diminution and nonexistence after death and is likewise compatible with various metaphysical positions about when posthumous harm occurs. The argument in question is provided by Keller (2004) and is compatible with analyses of welfare offered by Scanlon and Raz. Although I grant its underlying assumption that agency sometimes has a posthumous extension, I argue that my defense of the possibility of posthumous harm is superior to this one by expanding on a recent criticism of its position on welfare offered by Bradley (2007).
That Makes It Worse
Abstract: Essays on excusing conditions and their correlates, mitigating conditions, usually begin with the assumption that there is general agreement on what the standard excuses are, and on where they are inapplicable. This assumption is justified; criminal law and the history of discussions of excuses have produced accord, though now and then doubts are expressed about particulars. Essays on excuses typically aim not so much to convince one that such-and-such are the general types of excuses but, rather, to show how they work and what their operation reveals about the nature of voluntary acts, full responsibility, etc.
The pleasures of documentary tragedy
Abstract: Two assumptions are common in discussions of the paradox of tragedy: (1) that tragic pleasure requires that the work be fictional or, if non-fiction, then non-transparently represented; and (2) that tragic pleasure may be provoked by a wide variety of art forms. In opposition to (1) I argue that certain documentaries could produce tragic pleasure. This is not to say that any sad or painful documentary could do so. In considering which documentaries might be plausible candidates, I further argue, against (2), that the scope of tragic pleasure is limited to works that possess certain thematic and narrative features.
