The rosy dawn of my title refers to that optimistic time when the logical concept of a natural kind originated in Victorian England. The scholastic twilight refers to the present state of affairs. I devote more space to dawn than twilight, because one basic problem was there from the start, and by now those origins have been forgotten. Philosophers have learned many things about classification from the tradition of natural kinds. But now it is in disarray and is unlikely to be put back together again. My argument is less founded on objections to the numerous theories now in circulation, than on the sheer proliferation of incompatible views. There no longer exists what Bertrand Russell called ‘the doctrine of natural kinds’—one doctrine. Instead we have a slew of distinct analyses directed at unrelated projects.

Criminal forfeiture is an asset confiscation mechanism used to seize benefits gained from an offence that one is convicted of. In Kenya, the Proceeds of Crime and Anti-Money Laundering Act provides the facilitating legislation. The present state of the regime's underutilisation prompts an examination of the substantive law and procedure provided in this statute. The analysis indicates that the provisions are technical in nature and the process is systematic. This ensures that a procedurally and substantively fair process is undertaken, in keeping with constitutional provisions. Nonetheless, identified challenges, including the complex nature of the provisions, translate to unclear interpretation and consequently ineffective implementation. This state of affairs is reversible through increased understanding of the criminal forfeiture provisions and their operation. This can potentially lead to an upsurge in its use and facilitate depriving offenders of criminal gains, removing the incentive for crime and reducing proceeds available to fund criminal activities.

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.

Recently, Brian Ellis came up with a neat and novel idea about laws of nature, which at first I misunderstood. Then I participated, with Brian Ellis and Caroline Lierse, in writing a joint paper, “The World as One of a Kind: Natural Necessity and Laws of Nature” (Ellis, Bigelow and Lierse, forthcoming). In this paper, the Ellis idea was formulated in a different way from that in which I had originally interpreted it. Little weight was placed on possible worlds or individual essences. Much weight rested on natural kinds. I thought Ellis to be suggesting that laws of nature attribute essential properties to one grand individual, The World. In fact, Ellis is hostile towards individual essences for any individuals at all, including The World. He is comfortable only with essential properties of kinds, rather than individuals. The Ellis conjecture was that laws of nature attribute essential properties to the natural kind of which the actual world is one (and presumably the only) member.

I . Confronted with the acuteness of the socio-economic problems the two major labour organizations (i.e. : the socialist and the christiandemocratic trade union confederation) have in 1976 strengthened their «Common Trade Unions' Front» (with about two million members on a total of 2,300,000 wage- and salary earners in Belgium) in view of their negotiations with employers and with the government, to which the trade unions have submitted a common platform.The common front, that has its antecedents on the local, regional and professional level has never been and never will be of a permanent nature, some sort of organic unit. Each confederation maintains its own identity and the front is meant to be re-animated according to the circumstances.II. From the employers' side (and to some extent completely independent from the trade unions' common front) representatives of employers' organizations have «as a personal point of view» and, no doubt, as a preliminary approach, launched the idea that a new and very comprehensive «social pact» should be negotiated.  The socialist trade unions clearly tend to reject this idea, since it maywell lead to a further integration in the capitalist system, whereas the christiandemocratic union seems to be rather in favour of such a pact.In the present state of affairs (end of June, 1977) the probability that it be realized is rather low indeed.


This volume asks a question that is deceptive in its simplicity: Could international law have been otherwise? In other words, what were the past possibilities, if any, for a different law? The search for contingency in international law is often motivated, including in the present volume, by the refusal to accept the present state of affairs and by the hope that recovering possibilities of the past will facilitate a different future. The volume situates the search for contingency theoretically and within many fields of international law, such as human rights and armed conflict, migrants and refugees, the sea and natural resources, and foreign investment and trade. Today there is hardly a serious account that would consider the path of international law to be necessary and that would deny the possibility of a different law altogether. At the same time, however, behind every possibility of the past stands a reason – or reasons – why the law developed as it did. Those who embark in search of contingency soon encounter tensions when they want to recover past possibilities without downplaying patterns of determination and domination. Nevertheless, while warring critical sensibilities may point in different directions, only a keen sense of why things turned out the way they did makes it possible to argue about how they could plausibly have turned out differently.

This chapter approaches the ontological question, “What are natural kinds?” through another, partially linguistic, question. “What must natural kinds be like if the conventional wisdom about natural kind terms is correct?” Although answering this question will not tell us everything we want to know, it will, be useful in narrowing the range of feasible ontological alternatives. The chapter summarizes the contemporary linguistic wisdom and then tests different proposals about kinds against it. It takes simple natural kind terms—like “green,” “gold,” “water,” “tiger,” and “light”—to be Millian terms that rigidly designate properties typically determined by a reference-fixing stipulation to the effect that the general term is to designate whatever property provides the explanation of why, at actual world-state, all, or nearly all, the samples of items associated with the term by speakers who introduce it have the observational properties they do.
