The teleological approach to an epistemic concept investigates it by asking questions such as ‘what is the purpose of the concept?’, ‘What role has it played in the past?’, or ‘If we imagine a society without the concept, why would they feel the need to invent it?’ The idea behind the teleological approach is that examining the function of the concept illuminates the contours of the concept itself. This approach is a relatively new development in epistemology, and as yet there (...) are few works examining it. This paper aims to fill this gap and engender further understanding of the teleological method. I first contrast the teleological method with more orthodox approaches in epistemology. I then draw a three-way taxonomy of different kinds of teleological approach and provide an example of each kind. The teleological approach is often presented as antithetical to the more orthodox approaches in epistemology, and so in competition with them. I demur. I argue that the methods can be fruitfully combined in epistemological theorising; in the final section I suggest specific ways the teleological approach can be incorporated alongside more orthodox methods in a general methodological reflective equilibrium.

"The main and original contribution of this volume is to offer a discussion of teleology through the prism of religion, philosophy and history. The goal is to incorporate teleology within discussions across these three disciplines rather than restrict it to one as is customarily the case. The chapters cover a wide range of topics, from individual teleologies to collective ones; ideas put forward by the French aristocrat Arthur de Gobineau and the Scottish philosopher David Hume, by the Anglican (...) theologian and founder of Methodism, John Wesley, and the English naturalist Charles Darwin; it criss-crosses intellectually and conceptually from a discussion of morality to that of the sacralisation of politics"--.

Constitutivists seek to locate the metaphysical foundations of ethics in nonnormative facts about what is constitutive of agency. For most constitutivists, this involves grounding authoritative norms in the teleological structure of agency. Despite a recent surge in interest, the philosophical move at the heart of this sort of constitutivism remains underdeveloped. Some constitutivists—Foot, Thomson, and Korsgaard (at least in her recent *Self-Constitution*)—adopt a broadly Aristotelian approach. They claim that the functional nature of agency grounds normative judgments about agents in much (...) the same way that the functional natures of artifacts and bodily organs ground normative judgments about those kinds of things. I argue that the neo-Aristotelian conclusions about goodness which follow so straightforwardly from teleological premises are not genuinely normative. Functions are not by their very nature normatively significant. Other constitutivists—notably J. David Velleman and Paul Katsafanas—eschew Aristotelian talk of functions in favor of an approach based on the idea that agency has a constitutive aim. Velleman and Katsafanas both claim that aims are normatively significant. I argue that the fact that agency has a constitutive aim is merely a fact about the motives that produce and regulate actions. And so we are still left with a gap between the teleological and the normative. I conclude by suggesting that constitutivists have failed to find a way to bridge this gap not because none exists, but rather because they have been looking in the wrong place. The constitutivist project can be salvaged, but only if it is supplemented with a reductive metanormative account of reasons for action, an account that links reasons to sound or successful practical reasoning.

Teleological terms such as "function" and "design" appear frequently in the biological sciences. Examples of teleological claims include: A (biological) function of stotting by antelopes is to communicate to predators that they have been detected. Eagles' wings are (naturally) designed for soaring. Teleological notions were commonly associated with the pre-Darwinian view that the biological realm provides evidence of conscious design by a supernatural creator. Even after creationist viewpoints were rejected by most biologists there remained various grounds for concern about the (...) role of teleology in biology, including whether such terms are: 1. vitalistic (positing some special "life-force"); 2. requiring backwards causation (because future outcomes explain present traits); 3. incompatible with mechanistic explanation (because of 1 and 2); 4. mentalistic (attributing the action of mind where there is none); 5. empirically untestable (for all the above reasons). Opinions divide over whether Darwin's theory of evolution provides a means of eliminating teleology from biology, or whether it provides a naturalistic account of the role of teleological notions in the science. Many contemporary biologists and philosophers of biology believe that teleological notions are a distinctive and ineliminable feature of biological explanations but that it is possible to provide a naturalistic account of their role that avoids the concerns above. Terminological issues sometimes serve to obscure some widely-accepted distinctions. (shrink)

INTRODUCTION I What is teleology? If you ever look closely at an ants' nest, you will see an intricate network of pathways and chambers teeming with ...

INTRODUCTION The appeal to teleological principles of explanation within the body of natural science has had an unfortunate history. ...

-/- Some phenomena within nature exhibit such exquisiteness of structure, function or interconnectedness that many people have found it natural—if not inescapable—to see a deliberative and directive mind behind those phenomena. The mind in question, being prior to nature itself, is typically taken to be supernatural. Philosophically inclined thinkers have both historically and at present labored to shape the relevant intuition into a more formal, logically rigorous inference. The resultant theistic arguments, in their various logical forms, share a focus on (...) plan, purpose, intention and design, and are thus classified as teleological arguments (or, frequently, as arguments from or to design). -/- Although enjoying some prominent defenders over the centuries, such arguments have also attracted serious criticisms from a number of major historical and contemporary thinkers. Both critics and advocates are found not only among philosophers, but come from scientific and other disciplines as well. In the following discussion, major variant forms of teleological arguments will be distinguished and explored, traditional philosophical and other criticisms will be discussed, and the most prominent contemporary turns (cosmic fine tuning arguments, many-worlds theories, and the present Intelligent Design debate) will be tracked. Discussion will conclude with a brief look at one historically important non-inferential approach to the issue. (shrink)

Two separate research programs have revealed two different factors that feature in our judgments of whether some entity persists. One program—inspired by Knobe—has found that normative considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when the changes it undergoes lead to improvements. The other program—inspired by Kelemen—has found that teleological considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when it preserves its purpose. Our goal (...) in this paper is to determine what causes persistence judgments. Across four studies, we pit normative considerations against teleological considerations. And using causal modeling procedures, we find a consistent, robust pattern with teleological and not normative considerations directly causing persistence judgments. Our findings put teleology in the driver’s seat, while at the same time shedding further light on our folk notion of an object. (shrink)

Neo-teleology is the two part thesis that, e.g., (i) we have hearts because of what hearts are for: Hearts are for blood circulation, not the production of a pulse, so hearts are there--animals have them--because their function is to circulate the blood, and (ii) that (i) is explained by natural selection: traits spread through populations because of their functions. This paper attacks this popular doctrine. The presence of a biological trait or structure is not explained by appeal to its (...) function. To suppose otherwise is to trivialize natural selection. (shrink)

The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

This work is an examination of teleological attributions i.e. ascriptions of proper functions and natural ends) to the features and behavior of living things with a view to understanding their application to human life.

Placeholder essentialism is the view that there is a causal essence that holds category members together, though we may not know what the essence is. Sometimes the placeholder can be filled in by scientific essences, such as when we acquire scientific knowledge that the atomic weight of gold is 79. We challenge the view that placeholders are elaborated by scientific essences. On our view, if placeholders are elaborated, they are elaborated Aristotelian essences, a telos. Utilizing the same kinds of experiments (...) used by traditional essentialists—involving superficial change (study 1), transformation of insides (study 2), acquired traits (study 3) and inferences about offspring (study 4)—we find support for the view that essences are elaborated by a telos. And we find evidence (study 5) that teleological essences may generate category judgments. (shrink)

Natural/social kind essentialism is the view that natural kind categories, both living and non-living natural kinds, as well as social kinds (e.g., race, gender), are essentialized. On this view, artifactual kinds are not essentialized. Our view—teleological essentialism—is that a broad range of categories are essentialized in terms of teleology, including artifacts. Utilizing the same kinds of experiments typically used to provide evidence of essentialist thinking—involving superficial change (study 1), transformation of insides (study 2) and inferences about offspring (study 3)—we (...) find support for the view that a broad range of categories—living natural kinds, non-living natural kinds and artifactual kinds—are essentialized in terms of teleology. Study 4 tests a unique prediction of teleological essentialism and also provides evidence that people make inferences about purposes which in turn guide categorization judgments. (shrink)

Medieval and early modern Jewish philosophers developed their thinking in conversation with various bodies of literature. The influence of ancient Greek – primarily Aristotle (and pseudo-Aristotle) – and Arabic sources was fundamental for the very constitution of medieval Jewish philosophical discourse. Toward the late Middle Ages Jewish philosophers also established a critical dialogue with Christian scholastics. Next to these philosophical corpora, Jewish philosophers drew significantly upon Rabbinic sources (Talmud and the numerous Midrashim) and the Hebrew Bible. In order to clarify (...) the unique as well as shared elements in the thought of medieval Jewish philosophers, we will begin this chapter with a brief study of some early Rabbinic sources on the purpose of the world, i.e., why it came to be and why it is sustained in existence. In the second part of this chapter, we will study Maimonides’ critique of the veracity and usefulness of the belief in (anthropocentric) teleology, and the critical reception of his views by later philosophers. The third part will address discussions of divine teleology in Kabbalistic literature. Our exposition will concentrate mostly on a specific early-eighteenth-century text that is one of the most lucid and rigorous presentations of Lurianic Kabbalah. The fourth and final section will elucidate Spinoza’s critique of teleology, its precise target and scope, and its debt to earlier sources discussed in this chapter. (shrink)

This paper gives an account of evolutionary explanations in biology. Briefly, the explanations I am primarily concerned with are explanations of adaptations. These explanations are contrasted with other nonteleological evolutionary explanations. The distinction is made by distinguishing the different kinds of questions these different explanations serve to answer. The sense in which explanations of adaptations are teleological is spelled out.

Do young children have a teleological conception of the essence of natural kinds? We tested this by examining how the preservation or alteration of an animal’s purpose affected children’s persistence judgments (N = 40, ages 4 - 12, Mean Age = 7.04, 61% female). We found that even when surface-level features of an animal (e.g., a bee) were preserved, if the entity’s purpose changed (e.g., the bee now spins webs), children were more likely to categorize the entity as a member (...) of a different natural kind (e.g., a spider) and these effects were similar in magnitude to altering the surface-features of a natural kind. Our results suggest that we might view teleological properties as partially constitutive of the essence of natural kinds. (shrink)

The notions of purpose, goal, end and function are used in descriptions of a very wide range of human, animal and machine behaviour. Andrew Woodfield provides here a unified account of such teleological descriptions and explanations, their varieties, their logical structure and their proper uses. He concentrates his argument on the concepts of 'goal-directed behaviour' and 'natural function', and combines original philosophical criticism with a meticulous, detailed survey of the main competing theories in this diffuse and difficult field.

I explain what teleological reasons are, distinguish between direct and indirect teleological reasons, and discuss both whether all practical reasons are teleological and whether all teleological reasons are direct.

There are various forms of teleological thinking central to debates in the early modern and modern periods, debates in which David Hume (1711–1776) is a key figure. In the first section, we shall introduce three levels at which teleological considerations have been incorporated into philosophical accounts of man and nature, and sketch Hume’s criticisms of these approaches. In the second section, we turn to Hume’s non-teleological ‘science of man’. In the third section, we show how Hume has an account of (...) human flourishing that is not dependent on teleology. In the fourth section, we shall speculate as to the relation between Hume’s account of human nature and contemporary evolutionary accounts of morality and reasoning. (shrink)

In this paper, I consider Descartes’ Sixth Meditation dropsy passage on the difference between the human body considered in itself and the human composite of mind and body. I do so as a way of illuminating some features of Descartes’ broader thinking about teleology, including the role of teleological explanations in physiology. I use the writings on teleology of some ancient authors for the conceptual (but not historical) help they can provide in helping us to think about the (...) Sixth Meditation passage. From this, I draw several points, most notably that the Sixth Meditation passage is primarily concerned with the natures of body and composites, and that the issue of teleological explanation is derivative of this primary interest. So, we – and Descartes – must come to terms with what he takes the nature of the composite to be such that it has an intrinsic end-referred nature which grounds teleological explanations. I consider three possibilities: the human composite is a third type of substance – a hylomorphic substance; there is a sort of “satisfaction” relationship between mind and body (each of which retains its own distinct nature in the composite) such that the mind confers teleological value on the body; and there is a sort of “satisfaction” relationship between mind and body (each of which retains its own distinct nature in the composite) such that the mind recognizes teleological value in the body. None of these interpretations is without problems. So in the concluding section, I sketch a program for future research, specifically, trying to render Descartes’ teleological thinking consistent by distinguishing between the metaphysical natures of things (the concern of his Sixth Meditation passage) and the physical natures of things (his concern in his physiological writings).

The ancient origins of teleological concepts are sometimes either conveniently forgotten or given a distorted appearance. On the one hand, ancient teleology has been obscured by the theological cloak of creationism. On the other, Darwinists have sometimes failed to give due consideration to the variety and subtlety of teleology's intellectual antecedents. The purpose of this book is to restore the balance by looking at the manifold ways in which teleology in antiquity was viewed. The volume, consisting of (...) twelve essays by leading authorities in their fields, examines the ways in which teleological arguments were used in antiquity and how these discussions inform and influence current debates on evolution, creationism and intelligent design. As well as examining philosophical contributions to the subject, a specific aim is to examine ancient medical thinking on this topic and its relationship to ancient philosophical ideas. (shrink)

Following Chalmers, I take the most promising response to the meta-problem to be a realizationist one on which (roughly) consciousness plays a role in realizing the processes that explain why we think that there is a hard problem of consciousness. I favour an interactionist dualist version of realizationism on which experiences are non-physical states that non-redundantly cause problem judgments. This view is subject to the challenges of specifying laws that would enable experiences to cause problem judgments and of explaining why (...) it's not a lucky coincidence that experiences' causal and rational powers converge on problem judgments. I propose a strategy for solving the meta-problem and meeting these challenges. According to it, a fundamental teleological law operates on normative features of experiences in ways that bias experiences towards causing effects that they rationalize, including problem judgments. I conclude by applying the strategy to other luck-avoidance challenges. (shrink)

There’s a general assumption that teleology and function do not exist in inanimate nature. Throughout biology, it is generally taken as granted that teleology (or teleonomy) and functions are not only unique to life, but perhaps even a defining quality of life. For many, it’s obvious that rocks, water, and the like, are not teleological, nor could they possibly have stand-alone functions. This idea - that teleology and function are unique to life - is the target of (...) this paper. I begin with an overview of McShea’s field theoretic account of teleology. I start with the field theoretic account because it presents a promising analysis of teleological systems. It is promising because, in not making any assumptions about life’s special status in teleological systems, it avoids counterexamples that have problematized other accounts. I then consider some of the prominent efforts that have been made to attempt to avoid ascribing functions or teleology to some form of inanimate nature. In my assessment, none of the efforts are successful. I conclude by offering mineral evolution as a case study to show how inanimate nature can be both teleological and functional. The evolution of mineral species reveals that teleology and function extend to inanimate nature, and that teleology and function come in degrees. (shrink)

According to a widely held view of the matter, whenever we assess beliefs as ‘rational’ or ‘justified’, we are making normative judgements about those beliefs. In this discussion, I shall simply assume, for the sake of argument, that this view is correct. My goal here is to explore a particular approach to understanding the basic principles that explain which of these normative judgements are true. Specifically, this approach is based on the assumption that all such normative principles are grounded in (...) facts about values, and the normative principles that apply to beliefs in particular are grounded in facts about alethic value––a kind of value that is exemplified by believing what is true and not believing what is false. In this chapter, I shall explain what I regard as the best way of interpreting this approach. In doing so, I shall also show how this interpretation can solve some problems that have recently been raised for approaches of this kind by Selim Berker, Jennifer Carr, Michael Caie, and Hilary Greaves.

This paper argues that the account of teleology previously proposed by the authors is consistent with the physical determinism that is implicit across many of the sciences. We suggest that much of the current aversion to teleological thinking found in the sciences is rooted in debates that can be traced back to ancient natural science, which pitted mechanistic and deterministic theories against teleological ones. These debates saw a deterministic world as one where freedom and agency is impossible. And, because (...) teleological entities seem to be free to either reach their ends or not, it was assumed that they could not be deterministic. Mayr’s modern account of teleonomy adheres to this basic assumption. Yet, the seeming tension between teleology and determinism is illusory because freedom and agency do not, in fact, conflict with a deterministic world. To show this, we present a taxonomy of different types of freedom that we see as inherent in teleological systems. Then we show that our taxonomy of freedom, which is crucial to understanding teleology, shares many of the features of a philosophical position regarding free will that is known in the contemporary literature as ‘compatibilism’. This position maintains that an agent is free when the sources of its actions are internal, when the agent itself is the deterministic cause of those actions. Our view shows that freedom is not only indispensable to teleology, but also that, contrary to common intuitions, there is no conflict between teleology and causal determinism. (shrink)

Using the language of common-sense psychology, we explain human behavior by citing its reason or purpose, and this is central to our understanding of human beings as agents. On the other hand, since human beings are physical objects, human behavior should also be explicable in the language of physical science, in which causal accounts cast human beings as collections of physical particles. CSP talk of mind and agency, however, does not seem to mesh well with the language of physical science.In (...) Teleological Realism, Scott Sehon argues that CSP explanations are not causal but teleological -- that they cite the purpose or goal of the behavior in question rather than an antecedent state that caused the behavior. CSP explanations of behavior, Sehon claims, are answering a question different from that answered by physical science explanations, and, accordingly, CSP explanations and physical science explanations are independent of one another. Common-sense facts about mind and agency can thus be independent of the physical facts about human beings, and, contrary to the views of most philosophers of mind in recent decades, common-sense psychology will not be subsumed by physical science.Sehon defends his non-reductionist account of mind and agency in clear and nontechnical language. He carefully distinguishes his view from forms of "strong naturalism" that would seem to preclude it. And he evaluates key objections to teleological realism, including those posed by Donald Davidson's influential article "Actions, Reasons and Causes" and some put forth by more recent proponents of causal theories of action. CSP, Sehon argues, has a different realm than does physical science; the normative notions that are central to CSP are not reducible to physical facts and laws. (shrink)

This volume draws together Allan Gotthelf's pioneering work on Aristotle's biology. He examines Aristotle's natural teleology, the axiomatic structure of biological explanation, and the reliance on scientifically organized data in the three great works with which Aristotle laid the foundations of biological science.

Teleology in biology is making headline news in the United States. Conservative Christians are utilizing a teleological argument for the existence of a supremely intelligent designer to justify legislation calling for the teaching of "intelligent design" (ID) in public schools. Teleological arguments of one form or another have been around since Antiquity. The contemporary argument from intelligent design varies little from William Paley's argument written in 1802. Both argue that nature exhibits too much complexity to be explained by 'mindless' (...) natural forces alone. We need to postulate the existence of an intelligent designer, a creator with forethought and purpose. The inference to an intelligent creator harkens back to Plato’s teleological argument for the order of the cosmos. Plato’s demiurge is a creator that imposes order on the cosmos. Yet, as we shall see when we analyze the distinctly biological form of the more contemporary teleological arguments we will find remanants of Aristotle’s distinctive argument from functional arrangement, but without his distinctive form of telos which is unconscious and immanent rather than intelligent and creative from on high. The aim of this article is to survey various teleological arguments since Antiquity. Since a variant on Paley's argument—ID—is getting so much recent press I will start with a discussion on the nature of Paley’s teleology. (shrink)

This book explores a variety of teleology present in Plato's Republic, in which actions are carried out for the sake of an end that is not the intended goal. Payne draws on examples from Republic to demonstrate that performing some actions can help produce unintended results, which qualify as ends or purposes of human action.

Historical Teleologies in the Modern World tracks the fragmentation and proliferation of teleological understandings of history--the notion that history had to be explained as a goal-directed process--in Europe and beyond throughout the 19th and into the 20th century. Historical teleologies have profoundly informed a variety of other disciplines, including modern philosophy, natural history, literature, humanitarian and religious philanthropism, the political thought and practice of revolution, emancipation, imperialism, colonialism and anti-colonialism, the conceptualization of universal humankind, and the understanding of modernity in (...) general. By exploring the extension and plurality of historical teleology, the essays in this volume revise the history of historicity in the modern period. Historical Teleologies in the Modern World casts doubt on the idea that a single, if powerful, conception of time could function as the unifying principle of all modern historicity, instead pursuing an investigation of the plurality of modern historicities and its underlying structures. By bringing together Western and non-Western histories, this book provides the first extended treatment of the idea of historical teleology. It will be of great value to students and scholars of modern global and intellectual history"--From publisher's website. (shrink)

I argue for a teleological account of events in progress. Details aside, the proposal is that events in progress are teleological processes. It follows from this proposal that final causes are ubiquitous: anything happening at any time is an event with a telos.

The causal theory of action is widely recognized in the literature of the philosophy of action as the "standard story" of human action and agency--the nearest approximation in the field to a theoretical orthodoxy. This volume brings together leading figures working in action theory today to discuss issues relating to the CTA and its applications, which range from experimental philosophy to moral psychology. Some of the contributors defend the theory while others criticize it; some draw from historical sources while others (...) focus on recent developments; some rely on the tools of analytic philosophy while others cite the latest empirical research on human action. All agree, however, on the centrality of the CTA in the philosophy of action. The contributors first consider metaphysical issues, then reasons-explanations of action, and, finally, new directions for thinking about the CTA. They discuss such topics as the tenability of some alternatives to the CTA; basic causal deviance; the etiology of action; teleologism and anticausalism; and the compatibility of the CTA with theories of embodied cognition. Two contributors engage in an exchange of views on intentional omissions that stretches over four essays, directly responding to each other in their follow-up essays. As the action-oriented perspective becomes more influential in philosophy of mind and philosophy of cognitive science, this volume offers a long-needed debate over foundational issues.

This volume explores the intuitive yet puzzling concept of teleology as it has been treated by philosophers from the time of Plato and Aristotle to the present day. Philosophical discussions are enlivened and contextualized by reflections on the implications of teleology in medicine, art, poetry, and music.

Heidegger, like Kierkegaard, has recently been claimed as a narrativist about selves. From this Heideggerian perspective, we can see how narrative expands upon the psychological view, adding a vital teleological dimension to the understanding of selfhood while denying the reductionism implicit in the psychological approach. Yet the narrative approach also inherits the neo-Lockean emphasis on the past as determining identity, whereas the self is fundamentally about the future. Death is crucial on this picture, not as allowing for the possibility of (...) a final meaning to our lives, but as determining Dasein as ‘pure unactualizable possibility.’ Ultimately, therefore, narrative is not what constitutes selfhood – but this does not mean that narrative is not relevant to personal identity, because narrative allows identity to be expressed in action.

Teleological theories of content are thought to suffer from two related difficulties. According to the problem of indeterminacy, biological function is indeterminate in the sense that, in the case of two competing interpretations of the function of an evolved mechanism, there is often no fact of the matter capable of determining which function is the correct one. Therefore, any attempts to construct content out of biological function entail the indeterminacy of content. According to the problem of transparency, statements of biological (...) function are transparent in that a statement of the form 'the function of evolved mechanism M is to represent Fs' can be substituted salva veritate by a statement of the form 'the function of evolved mechanism M is to represent Gs' provided that the statement 'F iff G' is counterfactual supporting. Therefore, any attempt to construct content out of biological function must fail to capture the intensionality of psychological ascriptions. This paper argues that the teleological account is undermined by neither of these problems. Failure to appreciate this point stems from a conflation of two types of proper function - organismic and algorithmic - possessed by an evolved mechanism. These functions underwrite attributions of content to distinct objects. The algorithmic proper function of a mechanism underwrites attributions of content to the mechanism itself, while the organismic proper function of a mechanism underwrites attribution of content to the organism that possesses the mechanism. However the problems of indeterminacy and transparency arise only if the attributions of content attach to the same object. (shrink)

Explanation is a human activity. Teleological, causal, and evolutionary explanations are all valid forms of responding to particular puzzlements. Reductionism incorrectly assumes there is one absolute explanation. While causal explanation appeals primarily to necessity, evolutionary explanation is based largely on contingency.

Ernest Nagel, one of the world's leading philosophers of science, is an unreconstructed empirical rationalist who continues to believe that the logical methods of the modern natural sciences are the most successful instruments men have devised to acquire reliable knowledge. This book presents "Teleology Revisited"-the John Dewey lectures delivered at Columbia University- and eleven of Nagel's articles on the philosophy of science.

In this paper, I argue that Plotinus’s critique of divine deliberation in Ennead 6.7 does not seek to banish teleology altogether from his philosophy of nature. Rather, his critique aims to situate teleology within his own metaphysical system so as to reconcile it with the basic principles governing the intelligible universe. In this sense, Plotinus does not propose that we expunge all reference to notions of utility and benefit from our natural explanations; he merely wishes to render those (...) notions coherent with an ontology in which the intelligible always takes precedence over sensible reality. To this end, Plotinus introduces, first, what I call a vertical teleology, where the different animal species create the necessary conditions for the maintenance of higher forms of intelligible life, such as genera. Second, Plotinus advances what I call a horizontal teleology, where the various animal organs serve to provide a minimal coefficient of noetic content to each species in its respective ontic level. Plotinus thus sketches the outlines of a properly ‘noetic’ teleology in Ennead 6.7. (shrink)

This MPhil dissertation presents a novel account of teleological explanations in biology. I outline the “shorthand approach” to such explanations, on which they are taken to convey implicit evolutionary explanations. “Selected effects” accounts of teleological explanation dominate recent literature, but they struggle to accommodate teleological explanations of complex traits built through cumulative selection. I articulate the general notion of a landscape explanation, which, applied to biology, explains the evolution of complex features in a population by citing salient features of the (...) population’s fitness landscape. I show that such explanations lend themselves to a teleological shorthand. I close with remarks concerning when a teleological explanation of a trait is legitimate, and why teleological language strikes us as appropriate when we give evolutionary explanations. (shrink)

During the last century, most philosophers of science have tried to expunge teleological explanations from the fields of epistemology. They took for granted that the Darwinian concepts of natural selection and evolution effectively dispense us with any presence of goal-directedness in nature: based on an anti-metaphysical attitude, they hold purposes and goals to be of religious and spiritual nature, thereby obstacles to any effective comprehension of biological processes. Accordingly, teleological categories have been abandoned in many ways in favor of mechanical (...) causes and non-teleological processes: since Darwin demonstrated that no teleology is required in order to explain the natural world, causal explanations became the only tools to investigate natural processes.

This article analyses proportionality as a potential element of a theory of morally justified surveillance, and sets out a teleological account. It draws on conceptions in criminal justice ethics and just war theory, defines teleological proportionality in the context of surveillance, and sketches some of the central values likely to go into the consideration. It then explores some of the ways in which deontologists might want to modify the account and illustrates the difficulties of doing so. Having set out the (...) account, however, it considers whether the proportionality condition is necessary to a theory of morally justified surveillance. The article concludes that we need and should apply only a necessity condition, but notes that proportionality considerations may retain some use in in practice, as a form of coarse‐grained filter applied before assessing necessity when deliberating the permissibility of potential forms of surveillance.

Aristotelian natures – internal principles of motion and rest – provide a rich account of the goal-directed behaviour of natural entities. What such natures cannot account for, on their own, are cases of teleology across natures, where an entity, due to its nature, furthers the goals of another entity. Nevertheless, Aristotle admits such teleological configurations among natures: most notably Politics I.8 1256b15-20 claims that plants are for the sake of animals and animals are for the sake of humans. The (...) paper first scrutinizes two recent attempts– by Mohan Matthen and David Sedley – at an explanation of such teleology across natures. The fundamental move these proposals make is that they claim that the universe has a nature of its own. Accordingly, teleology across natures could be explained as the operation of this single cosmic nature. But the introduction of a cosmic nature contravenes fundamental strictures of Aristotelian natural philosophy. Hence the third section of the paper formulates an alternative proposal, that the teleological interaction across different natures is underpinned by the self-benefittingactivityofindividualnaturalentities,whichareable to use the natural processes of their environment to their own advantage.
