This chapter investigates non-causal scientific explanations that work by describing how the explanandum involves stronger-than-physical necessity by virtue of certain facts (“constraints”) that possess some variety of necessity stronger than ordinary causal laws possess. In particular, the chapter offers an account of the order of explanatory priority in explanations by constraint. It examines several important examples of explanations by constraint, distinguishing their natural kinds. It gives an account of the sense in which constraints are modally stronger than ordinary causal laws and an account of why certain deductions of constraints exclusively from other constraints possess explanatory power whereas others lack explanatory power.

This chapter explores how mechanisms and their constituents can be classified into kinds. It argues for a weakly realist account of natural kinds—one which suggests that classification into kinds is based upon real similarities between instances of those kinds, but which denies that kinds have essences or have some reality apart from their instances. I introduce a models-first account of kinds, which suggests that two things are of the same kind to the extent that they can be represented by the same model. Because target entities can be represented by multiple models, they will belong to multiple kinds. I illustrate the approach by showing how the entities and activities that make up mechanisms can be classified into kinds.

This chapter discusses the implications of Spinoza’s concept of individual bodies, as introduced in the definition of individuum in the physical digression. It begins by showing that this definition allows for an extremely wide application of the term; accordingly, very different sorts of physical entities can be described as Spinozistic individuals. Given the quite distinct use of the terms divisibilis and indivisibilis in his metaphysics, however, the chapter argues that the physical concept of individuality is not universally applied in the Ethics but reserved for physical or natural-philosophical considerations. The chapter concludes with a discussion of the problem of collective individuals. It is argued that, while societies or states are described as individual bodies, they do not constitute individual group minds in the strict sense of the term for Spinoza. This in turn indicates that minds are not individuated in the same way as bodies.

Abstract Plato’s invention of the metaphor of carving the world by the joints (Phaedrus 265d–66c) gives him a privileged place in the history of natural kind theory in philosophy and science; he is often understood to present a paradigmatic but antiquated view of natural kinds as possessing eternal, immutable, necessary essences. Yet, I highlight that, as a point of distinction from contemporary views about natural kinds, Plato subscribes to an intelligent-design, teleological framework, in which the natural world is the product of craft and, as a result, is structured such that it is good for it to be that way. In Plato’s Philebus, the character Socrates introduces a method of inquiry whose articulation of natural kinds enables it to confer expert knowledge, such as literacy. My paper contributes to an understanding of Plato’s view of natural kinds by interpreting this method in light of Plato’s teleological conception of nature. I argue that a human inquirer who uses the method identifies kinds with relational essences within a system causally related to the production of some unique craft-object, such as writing. As a result, I recast Plato’s place in the history of philosophy, including Plato’s view of the relation between the kinds according to the natural and social sciences. Whereas some are inclined to separate natural from social kinds, Plato holds the unique view that all naturalness is a social feature of kinds reflecting the role of intelligent agency.

In this paper I examine Aristotle’s biological use of the concept of analogy. On the reading I defend, biological analogues are parts that realize the same capacity of soul or occupy a similar location in the animals whose parts they are but are not specific (“more-and-less”) modifications of the same underlying material substratum. The concept of analogy serves two principal functions in Aristotle’s biology. First, Aristotle uses analogy as a tool for classifying animals into separate natural kinds (Part 3). Second, analogy plays an explanatory role in which the same causal explanation is transferred to “φ and its analogue” (Part 4). Here the function of analogy is to group different parts into a single explanatory class unified on the basis of shared causes. One of the upshots of my interpretation is that, while analogical unity may allow us to posit a common explanation for φ and its analogue, it is not grounds for treating the class of animals that ­possess those parts as a natural kind. For Aristotle, natural kinds are groups whose shared similarities must result from common causes operating on a common material substratum.

AbstractAre mental disorders (autism, ADHD, schizophrenia) natural kinds or socially constructed categories? What is at stake if either of these views prove to be true? This paper offers a qualified defence for the view that there may be natural kinds of mental disorder, but also that the implications of this claim are generally overestimated. Especially concerns about over-inclusiveness of diagnostic categories and medicalisation of abnormal behaviour are not addressed by the debate. To arrive at these conclusions the paper opens with a discussion of kind formation in science, followed by an analysis of natural kinds. Seven principled and empirically informed objections to the possibility of natural kinds of mental disorder are considered and rejected. The paper ends with a reflection on diagnostics of mental health problems that don’t fall into natural kinds. Despite the defence of the possibility of natural kinds of mental disorder, this is likely to be the majority of cases.

Science posits entities that are neither individuals nor properties but kinds of individuals that share a number of distinct properties. Philosophers have designated them “natural kinds” and have held different views about how to distinguish them from arbitrary collections of individuals. The doctrine of “kinds” or “natural groups” was first explicitly introduced by nineteenth-century philosophers interested in taxonomy or scientific classification and continues to be the subject of lively debate in contemporary philosophy. After canvassing some of the philosophical controversies regarding natural kinds, the article presents two influential contemporary theories of natural kinds: essentialism and the homeostatic property cluster theory. The article goes on to defend naturalism, which is more in tune with the findings of modern science.
