Sellars’ verbal behaviorism demands that linguistic episodes be conceptual in an underivative sense and his theoretical mentalism that thoughts as postulated theoretical entities be modelled on linguistic behaviors. Marras has contended that Sellars’ own methodology requires that semantic categories be theoretical. Thus linguistic behaviors can be conceptual in only a derivative sense. Further he claims that overt linguistic behaviors cannot serve as a model for all thought because thought is primarily symbolic. I support verbal behaviorism by showing that semantic categories are in the first instance teleological explanatory categories and consequently can be observational. And I show how theoretical mentalism can be maintained even though thought is primarily symbolic

Naturalism is often considered to be antithetical to theology and genuine religion. However, in a series of recent books and articles, Willem Drees has proposed a scientifically informed naturalistic account of religion, which, he contends, is not only compatible with supernaturalistic religion and theology but provides a better account of both than either purely naturalistic or purely supernaturalistic accounts. While rejecting both epistemological and methodological naturalism, Drees maintains that ontological naturalism offers the best philosophical account of the natural world and that, in addition, it provides the opening for a supernaturalistic understanding of religion and theology, one that best fits the condition of epistemic and moral distance from the transcendent characteristic of religious wonderers and wanderers. In this paper I examine Drees's claim and argue that it is seriously flawed. I show that Drees's naturalism is, in fact, both methodologically and epistemologically naturalistic. I also show that his attempts to limit naturalism to the sphere of the natural world by means of the phenomena of limit questions and underdetermination fail. Arguing for a more optimistic, but also, I contend, more empirically accurate account of human epistemic and moral capacities, I propose a full‐fledged scientifically based naturalistic account of theology.

In this paper I examine the feminist claim that non-epistemic values ought to play a role in scientific inquiry. I examine four holist arguments that non-epistemic values ought to play a role not only in the external aspects of scientific inquiry such as problem selection and the ethics of experimentation but also in its internal aspects, those that have to do with epistemic justification. In supporting their conclusion, I argue that they establish that the traditional external/internal distinction has served as a marker for more fundamental distinctions between non-epistemic and epistemic values and between the means by which each are pursued. However, I also contend that these arguments do nothing to deny these distinctions between epistemic and non-epistemic values. Maintaining these distinctions, I argue for an epistemic holism suggesting ways in which both substantive claims about non-epistemic values and reliable processes/methods for the legitimization of non-epistemic values may also be truth-conducive, thereby serving the epistemic ends of scientific inquiry.

Abstract.The thesis that the sciences are value neutral has recently been criticized severely. However, both the critics of the value‐neutrality thesis and its upholders share the separatist position that there is a fundamental dichotomy between fact and value, differing only on the degree to which science is impregnated with values. Skinner's claim that the science of operant behavior is the science of values rejects this dichotomy and is opposed to both the value‐neutrality thesis and criticisms of it. I examine Skinner's claim that psychology is value‐laden in the radical sense of providing a foundation for a theory of values and conclude that Skinner is arguing for an ethics and theory of values which is naturalistic, teleological, and both substantively and methodologically objective.

Although scientific naturalistic philosophers have been concerned with the role of scientific psychology in illuminating problems in moral psychology, they have paid less attention to the contributions that it might make to issues of moral ontology. In this paper, I illustrate how findings in moral developmental psychology illuminate and advance the discussion of a long-standing issue in moral ontology, that of moral realism. To do this, I examine Gilbert Harman and Nicholas Sturgeon's discussion of that issue. I contend that their explorations leave the issue unresolved. To break the stalemate, I appeal to empirical psychological findings about moral internalization—the process by which children acquire the capacity to act in terms of moral norms. I contend that these findings illuminate the issue, suggest a way to advance it, and tend to support a moral realist position.

Robert Richards has presented a detailed defense of evolutionary ethics, a revised version of Darwin's views and a major modification of E. O. Wilson's. He contends that humans have evolved to seek the community welfare by acting altruistically. And since the community welfare is the highest moral good, humans ought to act altruistically. Richards asks us to take his empirical premises on faith and aims to show how they can justify an ethical conclusion. He identifies two necessary conditions for a naturalistic justification of morality (NJ): its premises (1) must be empirical and (2) concerned with morally relevant causal factors. I argue that these two conditions are insufficient. An NJ must also appeal to teleogical or teleonomic laws which identify proper effects and reliable causes of these effects. So I supplement biological faith with an NJ that I believe has a better chance of working since faith without works is dead.

The continuing and expanding successes of behavior therapy in the treatment of psychological problems raise important questions about their scientific and philosophical bases. In this paper I examine the claims of Edward Erwin that behaviorism cannot provide an adequate philosophical basis for behavior therapy, contemporary learning theories which exclude cognitive factors as causes of behavior cannot provide an adequate empirical basis for behavior therapy; and learning theories have played only a heuristic role in the development of behavior therapy. And I argue that Erwin's claims rest on two doubtful logical empiricist assumptions about scientific theory and explanation. Using different assumptions, I argue that some of the regularities involving cognitions which seem to govern behavior therapy techniques are analogical extensions of operant learning principles. On this basis I suggest some modifications of Erwin's claim about the philosophical foundations of behavior therapy

Scholars of Wilfrid Sellars’s thought split into Right- and Left-wing Sellarsians. Right-wing Sellarsians urge Sellars’s scientific realism and the prominence of the scientific image of man in the synoptic vision. Left-wing Sellarsians emphasize the prominence of the logical space of reasons over that of causes, rejecting Sellars’s scientism. In his recent book James O’Shea attempts to reconcile these Sellarsian images, arguing that one best understands the Sellarsian synoptic image in terms of a norm/nature meta-principle that endorses the conceptual irreducibility and causal reducibility of norms. In this paper, I argue that O’Shea’s norm/nature meta-principle renders Sellars’s synoptic vision a Left-wing one. In its stead, I present a Sellarsian ideal: the view that Sellars ought to have held, whether he did so or not. My synoptic Sellarsian vision is based in part on the claim that Sellars found norms in nature and on a scientifically based philosophical account of norms in nature, whether these norms be biological, psychological, social, cultural or personal. I maintain then that Sellars was a Right-wing Sellarsian and that, if he wasn’t, he should have been. Indeed, a Sellars redivivus would be the leader of his party!

This paper continues the dialogue between my right-wing-Sellars and James O’Shea’s middle-Sellars. In it, I reply to O’Shea’s middle-Sellars critique of my right-wing-Sellarsian criticism of his recent attempt (Wilfrid Sellars: Wilfrid Sellars: Naturalism with a Normative Turn) to develop an understanding of Sellars’s overall view that avoids the problems of both right and left-wing-Sellarsians. In his contribution to this issue O’Shea argues that Sellars follows a middle way between left and right-wing-Sellarsians by advocating a refined Kantian naturalist account of human knowledge. In so doing he finds my right-wing interpretation of Sellars is not true to the real Sellars. Here I show that O’Shea’s critique of my right-wing-Sellars fails and that the real Sellars is a right-wing-Sellars, a scientific naturalist.

E. O. Wilson argues that we must use scientifically based reason to solve the values dilemma created by the loss of a transcendent foundation for values. Peter Singer allows that sociobiology can help us understand the evolutionary origin of ethics, but denies the claim that sociobiology or any science can furnish us with ultimate ethical principles. We argue that Singer's critique of Wilson's attempt to bridge the gap between fact and value using empirical reason is unconvincing and that Singer's own ethical principle of disinterestedness requires major support from empirical reason and is not sustainable by pure reason alone.
