Surviving the demise of his humoral pathology and anatomy, Galen’s works on simple and compound remedies (the so-called ‘galenicals’) formed the backbone of Western pharmacology up until the Industrial Revolution. Over its long and multicultural tradition—spanning the Roman Empire and Byzantium, through Islamicate societies, India, and China, to the New World and even Japan—Galenic pharmacopoeia evolved to incorporate new remedies, foods, philosophical rationales, and modes of preparation, including chemical ones. Despite its endurance, a systematic exploration of the use of galenicals beyond the Renaissance remains overdue. Addressing this gap, the contributions in this volume bring together leading scholars who illuminate how this medical tradition unfolded in the early modern period and its underlying dynamics, often drawing on new or overlooked archival material. Challenging the prevailing narrative of decline, they examine how pharmacological knowledge was transmitted across languages and medical traditions. Each contribution highlights an aspect of the various conceptual adaptations this process entailed, including textual transmission, debates over the structure of matter, occult qualities, dosage quantification, apothecary regulations, patient treatment, and the integration of galenicals into household medicine. Special attention is also given to the commodification of materia medica in Atlantic trade, while a comprehensive introduction contextualises the main themes of Galen’s post-Renaissance legacy and explores the reasons for its enduring vitality.

This chapter distinguishes between two mindsets about science—the deductivist mindset and inductivist mindset—and explores the cognitive styles relating to authority and tradition in both science and pseudoscience. The deductivist tends to see problems as questions to be resolved by deduction from known theory or principle. The inductivist sees problems as questions to be resolved by discovery. Those leaning towards a deductivist mindset may find results that conflict with prior theoretical commitments unacceptable. The deductivist tends to be a cognitive conservative, and the inductivist a cognitive progressive. The conservative mindset more often leads to resentment about modernism and hence about certain scientific results.

Selfhood and the Soul is a collection of new and original essays in honour of Christopher Gill, Emeritus Professor of Ancient Thought at the University of Exeter. Although they all share the same concern - the experience of being a person and the question of how best to live - as in the work of the honorand himself they are distinguished by a diversity of approach and subject matter, taking the reader on a journey from ancient philosophy to medical writing via discussions of topics as varied as money, love, free will, and cookery.

Discussions of dining in Roman literature often focus on moralising discourses of the satirists in the imperial period. This article seeks to extend the discussion in four areas: (1) a broader temporal frame, which runs from Cato the Elder to Athenaeus; (2) a wider cultural frame, which sets Greek commentaries of Rome alongside Rome's attitudes towards the Greeks; (3) a cultural range beyond Rome's elite, to the majority of the population; (4) a more ambitious literary frame, which presents Galen's discussion of food as texts of cultural richness rather than treatises reserved for medical historians.

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? In this chapter we apply this argument to beliefs in three different domains: morality, religion, and science. We identify replies to evolutionary scepticism that work in some domains but not in others. The simplest reply to evolutionary scepticism is that the truth of beliefs in a certain domain is, in fact, connected to evolutionary success, so that evolution can be expected to design systems that produce true beliefs in that domain. We call a connection between truth and evolutionary success a ‘Milvian bridge’, after the tradition which ascribes the triumph of Christianity at the battle of the Milvian bridge to the truth of Christianity. We argue that a Milvian bridge can be constructed for commonsense beliefs, and extended to scientific beliefs, but not to moral and religious beliefs. An alternative reply to evolutionary scepticism, which has been used defend moral beliefs, is to argue that their truth does not depend on their tracking some external state of affairs. We ask if this reply could be used to defend religious beliefs.

The longstanding species problem in biology has a history that suggests a solution, and that history is not the received history found in many texts written by biologists or philosophers. The notion of species as the division into subordinate groups of any generic predicate was the staple of logic from Aristotle through the middle ages until quite recently. However, the biological species concept during the same period was at first subtly and then overtly different. Unlike the logic sense, which relied on definitions of the essence of both genus and species, biological species from the time of Epicurus were consistently considered to involve a reproductive element: in short, living species relied not on essential definitions, but on the generative cause, which might not be definable. I term this the generative conception of species: species were the generation by reproduction of form. This undercuts the claim that species before Darwin were essentialist, and divorces the notion of a type from that of essence. In fact, as late as the end of the nineteenth century, logicians explicitly treated biological “species” as a homonym only of logical essentialist species, and permitted considerable deviation from the type or form. At every point, species in logic were thought to be a subset, in effect, of some more general notion. I sketch a history of both philosophical and biological traditions of the species concept, before turning to the current conceptions. These are reconsidered in the light of this history, and in particular Mayr’s changing views are shown to be somewhat Whiggish, historiographically. Of the many touted biological species concepts, only one of which (Mayr’s) is called _the_ Biological Species Concept, none appears to capture all the relevant facts, intuitions, and operational requirements of biology. Cladistic conceptions, however, have much in common with the older philosophical literature, in that the natural group of cladism is the clade, or monophyletic group. After considering the Individuality Thesis, and the metaphysics of species, we see that species are the most particular terminal taxa in a clade, and that they are “defined” in terms of the particular synapomorphies, or evolved characters, that are causally responsible for keeping the lineages that organisms form distinct from one another. In this way, we can remain within the generative conception of species that has been in play for over two millennia, and yet avoid the pitfalls of prior attempts to find a universal conception of species.

Intelligent design theorist William Dembski hasproposed an ``explanatory filter'' fordistinguishing between events due to chance,lawful regularity or design. We show that ifDembski's filter were adopted as a scientificheuristic, some classical developments inscience would not be rational, and thatDembski's assertion that the filter reliablyidentifies rarefied design requires ignoringthe state of background knowledge. Ifbackground information changes even slightly,the filter's conclusion will vary wildly.Dembski fails to overcome Hume's objections toarguments from design.

We argue that the logical outcome of the cladistics revolution in biological systematics, and the move towards rankless phylogenetic classification of nested monophyletic groups as formalized in the PhyloCode, is to eliminate the species rank along with all the others and simply name clades. We propose that the lowest level of formally named clade be the SNaRC, the Smallest Named and Registered Clade. The SNaRC is an epistemic level in the classification, not an ontic one. Naming stops at that level because there is no currently acceptable evidence for clades within it, not because no smaller clades exist. Later, included clades may be named. They would then become the SNaRCs, while the original SNaRC would keep its original name. We argue that all theoretical tasks of biology, in evolution and ecology, as well as practical tasks such as conservation assessment, are better approached using this rankless phylogenetic approach.

To naturalize religion, we must identify what religion is, and what aspects of it we are trying to explain. In this paper, religious social institutional behavior is the explanatory target, and an explanatory hypothesis based on shared primate social dominance psychology is given. The argument is that various religious features, including the high status afforded the religious, and the high status afforded to deities, are an expression of this social dominance psychology in a context for which it did not evolve: high-density populations made possible by agriculture

Creationism is usually regarded as an irrational set of beliefs. In this paper I propose that the best way to understand why individual learners settle on any mature set of beliefs is to see that as the developmental outcome of a series of “fast and frugal” boundedly rational inferences rather than as a rejection of reason. This applies to those whose views are opposed to science in general. A bounded rationality model of belief choices both serves to explain the fact that folk traditions tend to converge on “anti-modernity”, and to act as a default hypothesis, deviations from which we can use to identify other, arational, influences such as social psychological, economic and individual dispositions. I propose some educational and public policy strategies that might decrease the proportion of learners who find creationism and anti-science in general a rational choice.

An oft-repeated claim is that there is information in some biological entity or process, most especially in genes. Some of these claims derive from the Central Dogma, population genetics, and the neo-Darwinian program. Others derive from attacks upon evolution, in an attempt to show that “information cannot be created” by natural selection. In this paper I will try to show that the term “information” is a homonym for a range of distinct notions, and that these notions are either of concrete properties, in which case they are little more than a periphrasis for correlation and causation, or of abstract properties, in which case they are observer-dependent. In short, if information is in the concrete world, it is causality. If it is abstract, it is in the head.

The vision of natural kinds that is most common in the modern philosophy of biology, particularly with respect to the question whether species and other taxa are natural kinds, is based on a revision of the notion by Mill in A System of Logic. However, there was another conception that Whewell had previously captured well, which taxonomists have always employed, of kinds as being types that need not have necessary and sufficient characters and properties, or essences. These competing views employ different approaches to scientific methodologies: Mill’s class-kinds are not formed by induction but by deduction, while Whewell’s type-kinds are inductive. More recently, phylogenetic kinds (clades, or monophyletic-kinds) are inductively projectible, and escape Mill’s strictures. Mill’s version represents a shift in the notions of kinds from the biological to the physical sciences.
