The view of teleology sketched in the above remarks seems to me to offer a piece of candy to both the critics and guardians of teleology. The critics want to defend against a number of things: the importation of unverifiable theological or metaphysical doctrines into the sciences; the idea that goals somehow act in favor of their won realization; and the view that biological systems require for their study concepts and patterns of explanation unlike anything employed in the physical sciences. (...) An important part of their defense has been the contention that teleological language can be eliminated without loss from the sciences. I have argued that this is true: any phenomenon that can be described in teleological language can be described otherwise.On the other hand, eliminability does not mean translatability. I have suggested—I do not see how to prove it—that the teleological character of a sentence is so fundamental that it would be preserved under translation. Teleological character is conferred on a sentence by the manner in which it fits into a conceptual scheme designed for the description of certain classes of systems possessing net-like organization. The elimination of teleological language thus involves a conceptual shift, and involves a different method of classifying the elements of a system.The guardians of teleology—myself among them—have insisted that teleological language is perfectly legitimate. This conclusion is plain if my account of “appropriateness” is correct. Indeed, the development of conceptual schemes which render functional ascriptions appropriate is seen to be just a special case of a general scientific procedure: the designing of languages aimed at bringing to light those causal relations which are most interesting to us.

This paper is an attempt to re-interpret some of the results of contemporary studies of action and explanation by philosophers who may loosely be called 'post-Wittgensteinian', e.g. G. E. M. Anscombe, A. Kenny, A. I. Melden. One of the themes which recurs in these' discussions is that of the non-contingent connection between desires, intentions, etc., and the actions which we explain by them — although not all the authors concerned understand this in the same way, and many would not accept (...) the term 'non-contingent connection'. The thesis that there is a non-contingent connection between, e.g., desire and action is strongly contested, and I attempt in this paper to show (a) that our language for the factors which we cite in explaining action, desires, intentions (Sect. II), feelings (Sect. III), sensations (Sect. IV), etc. is inescapably dispositional in a strong sense, i.e. that it characterizes these factors as disposing us to act in certain ways. But I argue (b) that this does nothing to show that these factors are not causes of the actions they explain (Sect. I). The seeming oddity of causes which are non-contingently linked with their consequences is explained when we see (c) that the account of action embedded in our ordinary language is teleological, i.e. refers us ultimately to the inclinations of the subject, and intentional (Sects. V and VI). (shrink)

This essay has two goals. The first is to define the behavioristic study of natural events and to classify behavior. The second is to stress the importance of the concept of purpose.Given any object, relatively abstracted from its surroundings for study, the behavioristic approach consists in the examination of the output of the object and of the relations of this output to the input. By output is meant any change produced in the surroundings by the object. By input, conversely, is (...) meant any event external to the object that modifies this object in any manner. (shrink)
