Dispositional ascriptions do not entail the counterfactuals we might expect, as interfering factors may be poised to prevent the disposition from manifesting in its very stimulus conditions. Such factors are commonly called finks and masks. It is thought, however, that finks and masks cannot be intrinsic to the disposition bearer; if an intrinsic property of the object would prevent a particular response in certain conditions, the object fails to have the corresponding disposition. I argue that we should accept intrinsic finks (...) and masks if we think there are finks and masks at all, and also if we maintain that paradigmatic dispositions are intrinsic. This last point is particularly problematic for the claim that there cannot be intrinsic finks and masks, for if paradigmatic dispositions are not intrinsic then the central argument for the impossibility of intrinsic finks and masks is undermined.

I come not to clarify Aristotle’s defence of the principle of non-contradiction, but to put it in its proper context. I argue that remarks in Metaphysics IV.3 together with the argument of IV.4, 1006a11-31 show that Aristotle practises Plato’s method of dialectic in his defence of PNC. I mean this in the strong sense that he uses the very methodology described in the middle books of the Republic and, I claim, illustrated in such dialogues as Parmenides, Sophist and Theaetetus.

Drawing on different suggestions from the literature, we outline a unified metaphysical framework, labeled as Modal Meinongian Metaphysics (MMM), combining Meinongian themes with a non-standard modal ontology. The MMM approach is based on (1) a comprehension principle (CP) for objects in unrestricted, but qualified form, and (2) the employment of an ontology of impossible worlds, besides possible ones. In §§1–2, we introduce the classical Meinongian metaphysics and consider two famous Russellian criticisms, namely (a) the charge of inconsistency and (b) the (...) claim that naïve Meinongianism allows one to prove that anything exists. In §3, we have impossible worlds enter the stage and provide independent justification for their use. In §4, we introduce our revised comprehension principle: our CP has no restriction on the (sets of) properties that can characterize objects, but parameterizes them to worlds, therefore having modality explicitly built into it. In §5, we propose an application of the MMM apparatus to fictional objects and defend the naturalness of our treatment against alternative approaches. Finally, in §6, we consider David Lewis’ notorious objection to impossibilia, and provide a reply to it by resorting to an ersatz account of worlds. (shrink)

There is no question that the constituents of cells and organisms are joined together by the part-whole relation. Genes are part of cells, and cells are part of organisms. Species taxa, however, have traditionally been conceived of, not as wholes with parts, but as classes with members. But why does the relation change abruptly from part-whole to class-membership above the level of organisms? Ghiselin, Hull and others have argued that it doesn't. Cells and organisms are cohesive mereological sums, and since (...) species taxa are like cells and organisms in the relevant respects, they, too, are cohesive mereological sums. I provide further reasons in support of the thesis that species are mereological sums. I argue, moreover, that the advocate of this thesis is committed to a form of pluralism with respect to the species concept. (shrink)

Few notions are more central to Aquinas’s thought than those of matter and form. Although he invokes these notions in a number of different contexts, and puts them to a number of different uses, he always assumes that in their primary or basic sense they are correlative both with each other and with the notion of a “hylomorphic compound”—that is, a compound of matter (hyle) and form (morphe). Thus, matter is an entity that can have form, form is an entity (...) that can be had by matter, and a hylomorphic compound is an entity that exists when the potentiality of some matter to have form is actualized.1 What is more, Aquinas assumes that the matter of a hylomorphic compound explains certain of its general characteristics, whereas its form explains certain of its more specific characteristics. Thus, the matter of a bronze statue explains the fact that it is bronze, whereas its form explains the fact that it is a statue. Again, the matter of a human being explains the fact that it is a material object, whereas its form explains the specific type of material object it is (namely, human). My aim in this chapter is to provide a systematic introduction to Aquinas’s primary or basic notions of matter and form. To accomplish this aim, I focus on the two main theoretical contexts in which he deploys them—namely, his theory of change and his theory of individuation. In both contexts, as we shall see, Aquinas appeals to matter and form to account for relations of sameness and difference holding between distinct individuals. (shrink)

In this paper we examine and critique the constitution view of the metaphysics of resurrection developed and defended by Lynne Rudder Baker. Baker identifies three conditions for an adequate metaphysics of resurrection. We argue that one of these, the identity condition, cannot be met on the constitution view given the account of personal identity it assumes. We discuss some problems with the constitution theory of personal identity Baker develops in her book, Persons and Bodies . We argue that these problems (...) render the constitution theory of personal identity as stated by Baker untenable. The upshot for the debate over the metaphysics of resurrection is that the constitution view of the metaphysics of resurrection must either be rejected or modified. (shrink)

It is traditionally maintained that according to Aristotle, matter provides a principle of individuation. Objections of several sorts have been raised against this interpretation. One objection holds that for Aristotle it is form, rather than matter, that individuates. A more radical objection is that Aristotle does not propose any principle of individuation at all. Any adequate discussion of this issue must make clear precisely what problems such a principle is meant to address. This in turn requires that several important distinctions (...) be observed: (1) principles of individuation vs. principles of unity; (2) metaphysical vs. epistemological principles; (3) synchronic vs. diachronic unity and individuation; numerical vs. qualitative identity. After examining the objections in the light of these distinctions, I conclude that the objections cannot be sustained, and that, with appropriate qualifications, the traditional interpretation gives us the right idea about Aristotle.

The main lines of interpretation offered to date of the Third Man Argument in Plato's Parmenides (132a1-b2) are considered and rejected. A new, set-theoretic, reconstruction of the argument is offered. It is concluded that the philosophical point of the argument is different from what it has been generally supposed to be: Plato is pointing out the logical shortcomings in his earlier formulated principle of One-Over-Many.

This paper considers two strategies for undermining indispensability arguments for mathematical Platonism. We defend one strategy (the Trivial Strategy) against a criticism by Joseph Melia. In particular, we argue that the key example Melia uses against the Trivial Strategy fails. We then criticize Melia’s chosen strategy (the Weaseling Strategy.) The Weaseling Strategy attempts to show that it is not always inconsistent or irrational knowingly to assert p and deny an implication of p . We argue that Melia’s case for this (...) strategy fails.

There has been recent interest in formulating theories of non-representational indeterminacy. The aim of this paper is to clarify the relevance of quantum mechanics to this project. Quantum-mechanical examples of vague objects have been offered by various authors, displaying indeterminate identity, in the face of the famous Evans argument that such an idea is incoherent. It has also been suggested that the quantum-mechanical treatment of state-dependent properties exhibits metaphysical indeterminacy. In both cases it is important to consider the details of (...) the metaphysical account and the way in which the quantum phenomenon is captured within it. Indeed if we adopt a familiar way of thinking about indeterminacy and apply it in a natural way to quantum mechanics, we run into illuminating difficulties and see that the case is far less straightforward than might be hoped.

A critical review of Paul Bogossian's `Fear of Knowledge', focusing on his criticism of factual relativism.

Simon Evnine examines various epistemic aspects of what it is to be a person. Persons are defined as finite beings that have beliefs, including second-order beliefs about their own and others' beliefs, and are agents, capable of making long-term plans. It is argued that for any being meeting these conditions, a number of epistemic consequences obtain. First, all such beings must have certain logical concepts and be able to use them in certain ways. Secondly, there are at least two principles (...) governing belief that it is rational for persons to satisfy and are such that nothing can be a person at all unless it satisfies them to a large extent. These principles are that one believe the conjunction of one's beliefs and that one treat one's future beliefs as, by and large, better than one's current beliefs. Thirdly, persons both occupy epistemic points of view on the world and show up within those views. This makes it impossible for them to be completely objective about their own beliefs. Ideals of rationality that require such objectivity, while not necessarily wrong, are intrinsically problematic for persons. This "aspectual dualism" is characteristic of treatments of persons in the Kantian tradition. In sum, these epistemic consequences support a traditional view of the nature of persons, one in opposition to much recent theorizing. (shrink)

While the influential analytical philosopher Hilary Putnam has made significant contributions to philosophy of mind, philosophy of language and philosophy of science, he isn't generally regarded as a philosopher of religion or a theologian. Nonetheless, I argue that his work should be of great interest to philosophers of religion and theologians. Focusing on the relationship between science and religion, this paper explores the importance of Putnam's attempt to reconcile his anti-metaphysical stance and his commitment to a religious form of life (...) for theology. I first demonstrate why an anti-metaphysical stance and a commitment to Judaism can be deemed contradictory, and then characterize Putnam's anti-metaphysical stance as a modus vivendi to avoid both of what I call analytic and scientistic metaphysics. In a third step I offer my interpretation of Putnam's way of relating science and religion without metaphysics in the qualified sense, and subsequently spell out some important consequences of the emerging picture for theology. In my conclusion I give an account of Putnam as a transitional thinker, and draw a parallel between some of his work and Kierkegaard's “leap of faith”. (shrink)

Descartes claims that God is a substance, and that mind and body are two different and separable substances. This paper provides some background that renders these claims intelligible. For Descartes, that something is real means it can exist in separation, and something is a substance if it does not depend on other substances for its existence. Further, separable objects are correlates of distinct ideas, for an idea is distinct (in an objective sense) if its object may be easily and clearly (...) separated from everything that is not its object. It follows that if our idea of God is our most distinct idea, as Descartes claims, then God must be a substance in the Cartesian sense of the term. Also, if we can have an idea of a thinking subject which does not in any sense refer to bodily things, and if bodily things are substances, then mind and body must be two different substances.

Gödel's philosophical views were to a significant extent influenced by the study not only of Leibniz or Husserl, but also of Kant. Both Gödel and Kant aimed at the secure foundation of philosophy, the certainty of knowledge and the solvability of all meaningful problems in philosophy. In this paper, parallelisms between the foundational crisis of metaphysics in Kant's view and the foundational crisis of mathematics in Gödel's view are elaborated, especially regarding the problem of finding the “ secure path of (...) a science” for both mathematics and philosophy. Gödel's temporal subjectivism and metaphysical conceptual objectivism are presented as positively or negatively motivated by Kant's viewpoints. A remark on Gödel's collapse of modalities (in accordance with the collapse of objective time) is added. (shrink)

What are things like the Supreme Court? Gabriel Uzquiano has defended that they are groups, entities which are somehow composed of members (at certain times) but which, unlike sets (or pluralities), allow for fluctuation in membership. The main alternative holds that ‘the Supreme Court’ refers (at any time) to the set (or plurality) of their members (at the time). Uzquiano motivates his view by posing a metaphysical puzzle for this reductive alternative. I argue that a parallel reasoning would also find (...) a corresponding “puzzle” in the case of ordinary singular terms like 'The Chief Supreme Court Justice'. (shrink)

Much of my working life has been devoted to trying to get across the point that we urgently need to bring about a revolution in the aims and methods of academic inquiry, so that the basic aim becomes to seek and promote wisdom rather than just acquire knowledge.

For three decades I have expounded and defended aim-oriented empiricism, a view of science which, l claim, solves a number of problems in the philosophy of science and has important implications for science itself and, when generalized, for the whole of academic inquiry, and for our capacity to solve our current global problems. Despite these claims, the view has received scant attention from philosophers of science. Recently, however, David Miller has criticized the view. Miller’s criticisms are, however, not valid.

A Mug's Game? Solving the Problem of Induction with Metaphysical Presuppositions Nicholas Maxwell Emeritus Reader in Philosophy of Science at University College London Email: nicholas.maxwell@ucl.ac.uk Website: www.nick-maxwell.demon.co.uk Abstract This paper argues that a view of science, expounded and defended elsewhere, solves the problem of induction. The view holds that we need to see science as accepting a hierarchy of metaphysical theses concerning the comprehensibility and knowability of the universe, these theses asserting less and less as we go up the hierarchy. (...) It may seem that this view must suffer from vicious circularity, in so far as accepting physical theories is justified by an appeal to metaphysical theses in turn justified by the success of science. But this is rebutted. A thesis high up in the hierarchy asserts that the universe is such that the element of circularity, just indicated, is legitimate and justified, and not vicious. Acceptance of the thesis is in turn justified without appeal to the success of science. It may seem that the practical problem of induction can only be solved along these lines if there is a justification of the truth of the metaphysical theses in question. It is argued that this demand must be rejected as it stems from an irrational conception of science. (shrink)

In this paper I argue that physics makes metaphysical presuppositions concerning the physical comprehensibility, the dynamic unity, of the universe. I argue that rigour requires that these metaphysical presuppositions be made explicit as an integral part of theoretical knowledge in physics. An account of what it means to assert of a theory that it is unified is developed, which provides the means for partially ordering dynamical physical theories with respect to their degrees of unity. This in turn makes it possible (...) to assess the empirical fruitfulness of (some) metaphysical theses, in terms of the extent to which they play a role in empirically progressive scientific research programmes. A new conception of physics is developed which makes metaphysical theses an integral part of physics and which, at the same time, makes it possible to assess such theses in terms of their empirical fruitfulness. Circularity objections are rebutted. (shrink)

This paper considers Kripke's (1972, 1980) modal arguments against descriptivism about proper names, the descriptivist reply that the meaning of a name is given by a description involving the modifier ‘actually’, and Kit Fine's (1994) distinction between necessary and essential attributes. It explains how Kripke's modal arguments can be recast in essentialist terms by appealing to Fine's distinction, and it argues that the resulting essentialist arguments are immune to the abovementioned descriptivist reply to the original modal arguments.

Despite its admirable bottom-up methodology, Roy Sorensen's Seeing Dark Things (OUP, 2008) raises difficult theoretical questions concerning the metaphysics and perception of absences. Metaphysical difficulties include how to individuate, count, locate, and classify absences, and what determines their features. Perceptual difficulties include how to distinguish experiences of absences and presences, especially when nonveridical, and what subjects contribute to perceptual experience according to Sorensen's causal theory. In addition to articulating these difficulties, this paper also presents and explores, on Sorensen's terms, an (...) alternative account of silence. (shrink)

In 1980 a very interesting exchange of views between three distinguished philosophers took place. Two years earlier Armstrong had, in his already classical two-volume book on universals (Armstrong 1978a, 1978b), mentioned, in passing, Quinean positions as ”Ostrich or Cloak-anddagger Nominalism”, by which he referred to philosophers who refuse to countenance universals but who at the same time see no need for any reductive analysis. In the symposium in question (’Symposium: Nominalism’, Pacific Philosophical Quarterly 61 (1980)), Michael Devitt defended vigorously the (...) Quinean position and attacked Armstrong’s view (Devitt 1980); Armstrong naturally replied (Armstrong 1980), and Quine himself joined in with a short note (Quine 1980a). But interesting as these contributions are, the opinions have not exactly converged. (shrink)

The key argument of Hilary Putnam for conceptual relativism, his so-called mereological argument, is critically evaluated. It is argued that Putnam’s reasoning is based on confusion between languages and theories.

The thesis develops solutions to two main problems for mental realism. Mental realism is the theory that mental properties, events, and objects exist, with their own set of characters and causal powers. The first problem comes from the philosophy of science, where Psillos proposes a notion of scientific realism that contradicts mental realism, and consequently, if one is to be a scientific realist in the way Psillos recommends, one must reject mental realism. I propose adaptations to the conception of scientific (...) realism to make it compatible with mental realism. In the process, the thesis defends computational cognitive science from a compelling argument Searle can be seen to endorse but has not put forth in an organized logical manner. A new conception of scientific realism emerges out of this inquiry, integrating the mental into the rest of nature. The second problem for mental realism arises out of non-reductive physicalism- the view that higher-level properties, and in particular mental properties, are irreducible, physically realized, and that physical properties are sufficient non-overdetermining causes of any effect. Kim’s Problem of Causal Exclusion aims to show that the mental, if unreduced, does no causal work. Consequently, given that we should not believe in the existence of properties that do not participate in causation, we would be forced to drop mental realism. A solution is needed. The thesis examines various positions relevant to the debate. Several doctrines of physicalism are explored, rejected, and one is proposed; the thesis shows the way in which Kim’s reductionist position has been constantly inconsistent throughout the years of debate; the thesis argues that trope theory does not compete with a universalist conception of properties to provide a solution; and shows weakness in the Macdonald’s non-reductive monist position and Pereboom’s constitutional coincidence account of mental causation. The thesis suggests that either the premises of Kim’s argument are consistent, and consequently his reductio is logically invalid, or at least one of the premises is false, and therefore the argument is not sound. Consequently, the Problem of Causal Exclusion that Kim claims emerges out of non-reductive physicalism does not force us to reject mental realism. Mental realism lives on. (shrink)

A recent account of the meaning of 'real' leads to a view of what anti-realism should be that resembles fictionalism, while not being committed to fictionalism as such or being subject to some of the more obvious objections to that view. This account of anti-realism explains how we might 'make up' what is true in areas such as mathematics or ethics, and yet these made-up truths are resistant to alterations, even by our collective decisions. Finally it is argued that the (...) sort of anti-realism suggested explains the appearance that the ethical domain supervenes on the naturalistic. (shrink)

In this study I discuss G. W. Leibniz's (1646-1716) views on rational decision-making from the standpoint of both God and man. The Divine decision takes place within creation, as God freely chooses the best from an infinite number of possible worlds. While God's choice is based on absolutely certain knowledge, human decisions on practical matters are mostly based on uncertain knowledge. However, in many respects they could be regarded as analogous in more complicated situations. In addition to giving an overview (...) of the divine decision-making and discussing critically the criteria God favours in his choice, I provide an account of Leibniz's views on human deliberation, which includes some new ideas. One of these concerns is the importance of estimating probabilities – in making decisions one estimates both the goodness of the act itself and its consequences as far as the desired good is concerned. Another idea is related to the plurality of goods in complicated decisions and the competition this may provoke. Thirdly, heuristic models are used to sketch situations under deliberation in order to help in making the decision. Combining the views of Marcelo Dascal, Jaakko Hintikka and Simo Knuuttila, I argue that Leibniz applied two kinds of models of rational decision-making to practical controversies, often without explicating the details. The more simple, traditional pair of scales model is best suited to cases in which one has to decide for or against some option, or to distribute goods among parties and strive for a compromise. What may be of more help in more complicated deliberations is the novel vectorial model, which is an instance of the general mathematical doctrine of the calculus of variations. To illustrate this distinction, I discuss some cases in which he apparently applied these models in different kinds of situation. These examples support the view that the models had a systematic value in his theory of practical rationality. (shrink)

events all seem to have something in common, metaphysically speaking, and some philosophers have inquired into what this common nature is. The main aim of a theory of events is to propose and defend an identity condition on events; that is, a condition under which two events are identical. For example, if Brutus kills Caesar by stabbing him, are there two events, the stabbing and the killing, or only one event? Each of the leading theories of events is surveyed in (...) this article. According to Jaegwon Kim, events are basically property instantiations. In contrast, Donald Davidson attempts to individuate events by their causes and effects. However, Davidson eventually rejects this view and, together with W.V.O. Quine, individuates events with respect to their location in spacetime. According to David Lewis, an event is a property of a spatiotemporal region. (shrink)

Many people argue that history makes a special difference to the subjects of biology and psychology, and that history does not make this special difference to other parts of the world. This paper will show that historical properties make no more or less of a difference to biology or psychology than to chemistry, physics, or other sciences. Although historical properties indeed make a certain kind of difference to biology and psychology, this paper will show that historical properties make the same (...) kind of difference to geology, sociology, astronomy, and other sciences. Similarly, many people argue that nonhistorical properties make a special difference to the nonbiological and the nonpsychological world. This paper will show that nonhistorical properties make the same difference to all things in the world when it comes to their causal behavior and that historical properties make the same difference to all things in the world when it comes to their distributions. Although history is special, it is special in the same way to all parts of the world. (shrink)

Current approaches to formal representation in biomedicine are characterized by their focus on either the static or the dynamic aspects of biological reality. We here outline a theory that combines both perspectives and at the same time tackles the by no means trivial issue of their coherent integration. Our position is that a good ontology must be capable of accounting for reality both synchronically (as it exists at a time) and diachronically (as it unfolds through time), but that these are (...) two quite different tasks, whose simultaneous realization is by no means trivial. The paper is structured as follows. We begin by laying out the methodological and philosophical background of our approach. We then summarize the structure and elements of the Basic Formal Ontology on which it rests, in particular the SNAP ontology of objects and the SPAN ontology of processes. Finally, we apply the general framework to the specific domain of biomedicine. (shrink)

The history of evolution is a history of development from less to more complex organisms. This growth in complexity of organisms goes hand in hand with a concurrent growth in complexity of environments and of organism-environment relations. It is a concern with this latter aspect of evolutionary development that motivates the present paper. We begin by outlining a theory of organism-environment relations. We then show that the theory can be applied to a range of different sorts of cases, both biological (...) and non-biological, in which objects are lodged or housed within specific environments, or niches. Biological science is interested in types—for example in genotypes, phenotypes, and environment types—in regularities that can serve as the basis for the formulation of laws or general principles. Types, however, can exist only through their corresponding tokens. Our theory of token environments is meant to plug this gap and to provide a first step towards a general theory of causally relevant spatial volumes. (shrink)

The ecological literature distinguishes between two ways of conceiving a “niche” (habitat, ecotope, biotope, microlandscape) [22, 39]. On the one hand, there is the traditional functional conception of a niche as the role or position enjoyed by an organism or population within an ecological community. As C. Elton [14] famously put it, “When an ecologist says ‘there goes a badger’ he should include in his thoughts some definite idea of the animal’s place in the community to which it belongs, just (...) as if he had said ‘there goes the vicar’.” The world of niches might, in this sense, be viewed as a giant evolutionary hotel, some of whose rooms are occupied (by organisms which have evolved to fill them), some of whose rooms are for a variety of reasons unoccupied but can become occupied in the future. On the other hand, there is the environmental conception advanced by G. E. Hutchinson [19] and R. Lewontin [21]. On this second conception, a niche is thought of as the hypervolume defined by the limiting values of all environmental variables relevant to the survival of a given species. A niche is not a mere location, but a location in space that is defined additionally by a specific constellation of ecological parameters such as degree of slope, exposure to sunlight, soil fertility, foliage density, and so on. It is, we might say, an ecological context. The purpose of this paper is to outline a formal theory of this notion. Our account expands on the theory put forward in [30], which builds upon certain fundamental notions and principles of mereology, topology, and the theory of spatial location. We focus on niche tokens, which is to say on the environmental niche determined by a given organism or population of organisms in a given place, and we aim to be more explicit than is customary in the ecological literature as concerns the..

We propose the beginnings of a general theory of environments, of the parts or regions of space in which organisms live and move. We draw on two sources: on the one hand on recent work on the ontology of space; and on the other hand on work by ecological scientists on concepts such as territory, habitat, and niche. An environment is in first approximation a volume of space; it is a specific habitat, location, or site that is suitable or adequate (...) for given purposes (of foraging, resting, hunting, breeding, nesting, grooming) in the life of an organism or group of organisms. This spatial notion of environment can be drawn closer to biological and ecological science by taking account of the pertinent physical attributes realized within given spatial regions. (shrink)

I shall argue that there is no such property of an event as its “probability.” This is why standard interpretations cannot give a sound definition in empirical terms of what “probability” is, and this is why empirical sciences like physics can manage without such a definition. “Probability” is a collective term, the meaning of which varies from context to context: it means different — dimensionless [0, 1]-valued — physical quantities characterising the different particular situations. In other words, probability is a (...) reducible concept, supervening on physical quantities characterising the state of affairs corresponding to the event in question. On the other hand, however, these “probability-like” physical quantities correspond to objective features of the physical world, and are objectively related to measurable quantities like relative frequencies of physical events based on finite samples — no matter whether the world is objectively deterministic or indeterministic.

Introduction to my 'Contemporary Aristotelian Metaphysics' volume.

We argue that not all cases of before-effect involve causation and ask how to demarcate cases of before-effect in which the events that follow exert causal influence over the before-effect from cases in which they do not.

Formal principals are isolated to reveal a structure embedded in a wide range of studies, each of which partitions a domain of individuals into types and categories. It is thought that any reasonable theory of types should include these principles.

If the world itself is metaphysically indeterminate in a specified respect, what follows? In this paper, we develop a theory of metaphysical indeterminacy answering this question.

Might the world really be vague, as opposed to merely being vaguely represented? Arguments that it cannot be are in no short supply, but a notable feature of many such arguments is that they rely on assumptions that the defender of metaphysical vagueness either tacitly or explicitly rejects.

Contemporary philosophers commonly suppose that any fundamental entities there may be are maximally determinate. More generally, they commonly suppose that, whether or not there are fundamental entities, any determinable entities there may be are grounded in, hence less fundamental than, more determinate entities. Hence, for example, Armstrong takes the physical objects constituting the presumed fundamental base to be “determinate in all respects” (1961, p. 59) and Lewis takes the properties characterizing things “completely and without redundancy” to be “highly specific” (1986, (...) 60). Here I’ll look at the usually cited reasons for these suppositions, and argue that none is compelling. My discussion will moreover identify a positive reason for taking some determinable entities to be part of a fundamental (or relatively fundamental) base. (shrink)
