On the general argument against internalism

I respond to John Greco’s argument that all forms of internalism in epistemology are either false or uninteresting. The paper divides into two sections. First, I explain precisely what internalists and externalists in epistemology disagree over. This puts us in a position to assess whether Greco’s argument succeeds. Second, I present Greco’s argument and offer two objections.     

A Davidsonian argument against incommensurability

The writings of Kuhn and Feyerabend on incommensurability challenged the idea that science progresses towards the truth. Davidson famously criticized the notion of incommensurability, arguing that it is incoherent. Davidson's argument was in turn criticized by Kuhn and others. This article argues that, although at least some of the objections raised against Davidson's argument are formally correct, they do it very little harm. What remains of the argument once the objections have been taken account of is still quite damaging to the thesis that formerly endorsed scientific theories are incommensurable with those of today's science.     

A psychofunctionalist argument against nonconceptualism

In this paper I present a psychofunctionalist argument for conceptualism, the thesis that conscious visual experience is a conceptual state rather than a nonconceptual state. The argument draws on the holistic character of functionalist accounts of mind, together with the “Two Visual Systems Hypothesis” notably defended by Melvyn Goodale and David Milner.

A fallacious argument against moral absolutes

The denial of moral absolutes rests, I think, on a seductive but fallacious argument, which I shall attempt both to expound and to refute here. Human beings are highly complex creatures living in a highly complex world. Every human being is different from every other, every interaction or relationship between or among human beings is unique. Hence also every occasion for moral choice is also unique, and all those action kinds - be theyadultery, murder, rape, theft, ortorture on which moralists are accustomed to pass judgment include an enormous variety of differing transactions, which ideally ought to be evaluated one by one. Moreover, each proposed action has a variety of different aspects: intention, foreseen consequence, conventional meaning, and symbolic significance for example, which bear on moral choice in a wide variety of ways. Moral rules are therefore rules of thumb, open to exceptions whenever persuasive arguments for making them are provided.     

A utilitarian argument against torture interrogation of terrorists

Following the September 2001 terrorist attacks on the United States, much support for torture interrogation of terrorists has emerged in the public forum, largely based on the “ticking bomb” scenario. Although deontological and virtue ethics provide incisive arguments against torture, they do not speak directly to scientists and government officials responsible for national security in a utilitarian framework. Drawing from criminology, organizational theory, social psychology, the historical record, and my interviews with military professionals, I assess the potential of an official U.S. program of torture interrogation from a practical perspective. The central element of program design is a sound causal model relating input to output. I explore three principal models of how torture interrogation leads to truth: the animal instinct model, the cognitive failure model, and the data processing model. These models show why torture interrogation fails overall as a counterterrorist tactic. They also expose the processes that lead from a precision torture interrogation program to breakdowns in key institutions—health care, biomedical research, police, judiciary, and military. The breakdowns evolve from institutional dynamics that are independent of the original moral rationale. The counterargument, of course, is that in a society destroyed by terrorism there will be nothing to repair. That is why the actual causal mechanism of torture interrogation in curtailing terrorism must be elucidated by utilitarians rather than presumed.     

The reductio argument against epistemic infinitism

Synthese - Epistemic infinitism, advanced in different forms by Peter Klein, Scott Aikin, and David Atkinson and Jeanne Peijnenburg, is the theory that justification of a proposition for a person...
