Teleology ( study of design, Purpose , directive principle, or finality in nature or human creations. It is traditionally contrasted with Philosophical Naturalism , which views nature as lacking design or purpose. In opposition to this, teleology holds there is a final cause or purpose inherent in all beings. There are two types of such causes, Intrinsic Finality and Extrinsic Finality . Historically, teleology may be identified with Aristotelianism and the scholastic tradition in philosophy, again, made central to speculative philosophy by Hegel . The rationale of teleology was explored in detail by Immanuel Kant in his Critique Of Judgement . Friedrich Engels refuted teleology as Pantheism or Deism and defended Darwin 's evolution theory. In Theology , " Intelligent Design " is a Teleological Argument for the existence of God. In Bioethics , teleology is used to describe a Utilitarian view that an action's ethical right or wrong is based on the balance of good or bad consequences. TELEOLOGY VERSUS PHILOSOPHICAL NATURALISM Teleology traditionally is contrasted with Philosophical Naturalism , which views nature as lacking design or purpose. Teleology would argue that a person has eyes because he has the need of eyesight, Form Follows Function , while naturalism is the reverse of this position: it would say that a person has sight simply because he has eyes, or that function follows form (eyesight follows from having eyes). Organisms with eyes may be more successful at interacting with the world, so organisms with eyes survive long enough to produce offspring whereas organisms without eyes die without offspring. Two classic examples of these opposing views are found in Aristotle and Lucretius , the former as a supporter of teleology and the latter as a supporter of what is now often called philosophical naturalism, or Accidentalism : EXTRINSIC AND INTRINSIC FINALITY Teleology depends on the concept of a final cause or purpose inherent in all beings. There are two types of such causes, intrinsic finality and extrinsic finality.
Over-emphasizing extrinsic finality is often criticized as leading to the Anthropic attribution of every event to a divine purpose, or Superstition . For instance, "If I hadn't been at the store today, I wouldn't have found that $100 on the ground. God must have intended for me to go to the store so I would find that money." or "We won the game today because of my lucky socks." Such abuses were criticized by Francis Bacon ("De Dignitate et Augmentis Scientiarum," III, iv), Descartes ("Principia Philosophiæ", I, 28; III, 2, 3; "Meditationes", III, IV), and Spinoza ( Ethica , I, prop. 36 app.). Intrinsic finality, while more subtle, provides the basis for the Teleological Argument for the existence of God and or some supernatural force, and its modern counterpart, Intelligent Design . However, this argument can be turned squarely on its head by Darwinism, and the American philosopher Daniel Dennett devoted a book, Darwin's Dangerous Idea, to outlining the profound implications of this counter-intuitive inversion. Proponents of teleology argue that it resolves a fundamental defect in philosophical naturalism. They argue that naturalism focuses exclusively on the immediate causes and mechanisms of events, and does not attend to the reason for their synthesis. Thus, it is argued, if we take a clock apart, we discover in it nothing but springs, wheels, pivots, levers etc. But having explained the mechanism which causes the revolutions of the hands on the dial, is it reasonable to say that the clock was not made to keep time? Philosophers of science respond that since Aristotle, biology has been profoundly concerned with the constraint function places on structure, and that the arrival of Darwinian evolutionary theory did not alter this concern. A classic and early example is Darwin's interest in functional constraints on the evolutionary development of the beaks of Galapagos finches. Of these birds, Darwin wrote, "Seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends. " ('' Origin Of Species '', chapter 19) CLASSICAL GREEK TELEOLOGY Plato summarized the argument for teleology as follows in Phaedo , arguing that it is error to fail to distinguish between the ultimate Cause, and the mere means by which the ultimate Cause acts: Thus, it is argued, those who attempt to explain nature in terms of nature alone are forced to deny the ultimate binding Good (or other such invisible forces, such as gravity and electromagnetism) in the universe, and hope that they will someday discover a stronger supporting argument ("Atlas" or, for example, God) to hold their universe together. Similarly, Aristotle argued that it is error to attempt to reduce all things to mere necessity, because such thinking neglects the purpose, order, and "final cause" that causes the apparent necessity. He wrote: In addition to the final cause, Aristotle's analysis speaks of the Material Cause , Efficient Cause , and Formal Cause . MODERN/POSTMODERN PHILOSOPHY Historically, teleology may be identified with the philosophical tradition of authors, from Lukács and Jaspers to Horkheimer and Adorno . According to Jean-François Lyotard (1979) teleology and " Grand Narrative s" are eschewed in a Postmodern attitude. Teleology may be viewed as reductive, exclusionary and harmful to those whose stories are erased.Lochhead, Judy (2000). ''Postmodern Music/Postmodern Thought'', p. 6. (ISBN 0-8153-3820-1) Against this, Alasdair MacIntyre has argued that a narrative understanding of one's self is liberatory, in understanding one's capacity as an independent reasoner and, also, in understanding one's dependence on others and on the social practices and traditions in which one participates. Social practices may be understood as teleologically orientated to internal goods. For example, practices of philosophical and scientific enquiry are teleologically ordered to the elaboration of a true understanding of their objects. Although beginning with his book '' After Virtue '', which famously dismissed the naturalistic teleology of Aristotle's 'metaphysical biology', MacIntyre has cautiously moved from that book's account of a sociological teleology toward an exploration of what remains valid in a more traditional teleological naturalism. SCIENCE Anthropic principle In recent decades, a form of teleological reasoning has reappeared in certain quarters of ) but has since grown ever more complex, to the extent that it is hospitable to human life, even more so than is necessary for survival -- for example, advanced human civilization? Philosophy of science Contemporary accounts of teleology within biology are heavily influenced by Millikan, Ruth. Varieties of Meaning (The 2002 Jean Nicod Lectures) (Cambridge, Mass : MIT Press, 2004) for instanceFor a collection of essays mostly in the line of Wright's thought, see David J. Buller, Function, Selection, and Design (State University of New York Press, 1999)). There is, however, disagreement over its use. Some, such as ,Mayr, Ernst. The Idea of Teleology, Journal of the History of Ideas (Vol. 53 1992 ), pp. 117-135. object to any sort of Etiological theory of teleology that attempts to explain both natural phenomena as well as human artifacts. Their accounts are therefore naturalistic accounts of teleology. For a very detailed discussion of this resurgence of teleology in natural science, see Barrow and Tipler (1986). While long stretches of this monograph are technically challenging, it also includes:
Barrow and Tipler include many references. Teleological considerations also inform some of the writings of Arthur Eddington , Freeman Dyson , and John Wheeler . Technology Teleology has a long history in the study of purpose in human creations such as technology. The study of "teleological mechanisms" in machinery (i.e. machines with corrective feedback) dates back at least to the late 1700s when James Watt 's steam engine was equipped with a Governor . More recently, Julian Bigelow , Arturo Rosenblueth , and Norbert Wiener conceived of teleology in machinery as being a Feedback Mechanism . Wiener, a mathematician, coined the term ' Cybernetics ' to denote the study of "teleological mechanisms," which was popularized through his book ''Cybernetics, or control and communication in the animal and machine'' ( 1948 ). Cybernetics is the study of the Communication and Control of regulatory Feedback , both in living beings and machines, and in combinations of the two. In ,1993, where ''teleological'' represents the subjective requirement for every intelligent system). In such sense, for example, all engineering is, by definition, teleological, as well as, every human rational mental act is also oriented on a goal. Teleonomy In recent years, end-driven teleology has become contrasted with "apparent" teleology, i.e Teleonomy or process-driven systems. SEE ALSO
