This special issue for the Journal for General Philosophy of Science is devoted to exploring the impact and many ramifications of current research in evolutionary epistemology. Evolutionary epistemology is an inter- and multidisciplinary area of research that can be divided into two ever-inclusive research avenues. One research avenue expands on the EEM program and investigates the epistemology of evolution. The other research avenue builds on the EET program and researches the evolution of epistemology. Since its conception, EE has developed three schools of thought: adaptationist, non-adaptationist, and applied EE. Although diverse in outlook and theoretical background, these research avenues and schools share the same agenda of understanding how knowledge evolves, and how it relates to the world. In this paper, we first explain wherefrom evolutionary epistemological schools of thought developed, and then we highlight current debates in EE by briefly reviewing the papers that form part of this special issue.

The fundamental dialectic of Science as a Process is the interaction between two narrative levels. At one level, the book is a historical narrative of one aspect of one ongoing problem in systematics - the dispute between cladists and more traditional evolutionary taxonomists and amongst the cladists themselves on the correct method of classifying species. This narrative is replete with details of the process whereby scientists promote and publish their ideas. It is an informative and somewhat ‘racy’ account of the rough and tumble battleground of ideas which puts the lie to the mythical ideal of the scientist as disinterested pursuer of the Truth. At the second level, Hull presents a theoretical model of the scientific process - a model which draws heavily on invoked similarities between biological and scientific change. The narrative serves as the evidence for the model. The model, in turn, helps shape the historical narrative.

INTRODUCTIONThe contemporary debate over the moral status of animals reflects a mixture of traditions. Utilitarianism, which measures moral standing in terms of the ability to suffer, has been used to defend the widening-circle conception of morality. The difference between humans and other animals vis-à-vis moral standing diminishes in its light. Focusing on questions of agency, conscience, and reflective powers, the differences between humans and nonhumans seem greater. Darwinism has been invoked to bridge the gaps between the intellectual and moral capacities of humans and those of other animals. This has led some to argue either that differences in agency, conscience, and the power to reflect are overrated or that they may not be absolute indicators of moral consideration.Debates over the moral status of nonhuman animals have had a long and stormy history. The considerations that drive the current debate – questions of the intellectual capacities of animals, questions about their moral sensibilities, and questions about their sensitive capacities – are ancient. Nonetheless, they first began to assume their modern form in the writings of the eighteenth-century British moral philosophers. Those individuals were struggling with the moral implications of discoveries in the natural sciences and an increasingly secularized approach to philosophical issues. Vivisection experiments and rudimentary anatomical studies not only showed that the bodies of animals were remarkably similar to the bodies of human beings but also showed that the brutes were capable of experiencing pain and suffering.

The most trenchant criticism of naturalistic approaches to epistemology is that they are unable to successfully deal with norms and questions of justification. Epistemology without norms, it is alleged, is epistemology in name only, an endeavor not worth doing. What one makes of this depends on whether one takes epistemology to be worth doing in the first place. However, I shall argue, it is possible to account for justification within a naturalistic framework broadly construed along Quinean lines. Along the way I shall offer a corrective to Quine’s celebrated dictum that the Humean condition is the human condition.

Lynch, Parke, and O’Malley highlight the need for better evaluative criteria for causal explanations in microbiome research. They propose new interventionist criteria, show that paradigmatic examples of microbiome explanations are flawed using those criteria, and suggest numerous ways microbiome explanations can be improved. While we endorse their primary criticisms and suggestions for improvements in microbiome research, we make several observations regarding the use of mooted causal models in microbiome research that have significant implications for their overall argument. In sum, we contend that their critique is too modest and that even flawed causal inferences like those they criticize can be valuable for generating better causal models and evaluating explanatory outcomes in individual cases.

From 1914 on Russell's epistemology was dominated by the attempt to show how we come by our knowledge of the external world. As he gradually became aware of the inadequacies of the "pure empiricist" approach, Russell realized that his program was viable only insofar as certain postulates of inference were allowed. In this paper I trace the development of the structural postulates from Analysis of Matter to Human Knowledge. The basic continuity of Russell's thought is established. Certain confusions implicit in the various formulations of the postulates are brought to light. Finally, it is argued that the viability of Russell's program rests on a larger number of independent postulates than he thought were needed. Some implications of Russell's work for current work in the philosophy of science are briefly sketched.

Wesley Salmon defends an ontic realism that distinguishes explanatory from descriptive knowledge. Explanatory knowledge makes appeals to (unobservable) theoretical acausal mechanisms. Salmon presents an argument designed both to legitimize attributing truth values to theoretical claims and to justify treating theoretical claims as descriptions. The argument succeeds but only at the price of calling the distinction between explanation and description into question. Even if Salmon's attempts to distinguish causal mechanisms from other mechanisms are successful, the assumed centrality of the appeal to such mechanisms in providing scientific explanations is left open by Salmon's account.

The fundamental dialectic of Science as a Process is the interaction between two narrative levels. At one level, the book is a historical narrative of one aspect of one ongoing problem in systematics. At the second level, Hull presents a theoretical model of the scientific process which draws heavily on invoked similarities between biological and scientific change. I first situate the model as one alternative among several which loosely fit under the umbrella of 'evolutionary epistemologies.' Second, I explore one of the implications of Hull's model, namely, that insofar as scientific theories are [parts of] "conceptual lineages," they are "conceptual individuals.".
