L'A. étudie la concurrence entre la matière, la forme et la composition de matière et de forme, pour le titre de substance première ousia dans la «Métaphysique» Z, 3 d'Aristote. L'A. s'oppose à l'interprétation qu'en donne L. Gill dans son livre «Aristotle on Substance: The Paradox of Unity», selon laquelle l'ει~δο et la composition sont toutes deux premières. L'A. propose une explication qui s'inscrit dans le cadre métaphysique de la théorie de la recherche.

In this radical reinterpretation of Aristotle's Metaphysics, Walter E. Wehrle demonstrates that developmental theories of Aristotle are based on a faulty assumption: that the fifth chapter of Categories is an early theory of metaphysics that Aristotle later abandoned.

Huemer [33] argues against the killing of animals. I offer a critical libertarian analysis of his claim.

What is the proper punishment from the perspective of the libertarian philosophy? More specifically, in what way, if at all, may a thief benefit from his robbery? The present essay attempts to wrestle with these challenging questions.

There is a new sheriff in town on the abortion question. It is called evictionism. It diverges, philosophically, from both the pro-life and the pro-choice positions. It assumes that the birth of a human being starts with the fertilized egg but claims that the unwanted baby is a trespasser that may be evicted in the gentlest manner possible.

Heumer and I debate animal rights, utilitarianism, libertarianism, morality and philosophy. We agree that suffering is a problem, and diverge, widely, on how to deal with it. I maintain that this author’s reputation as a libertarian, let alone an intellectual leader of this movement, is problematic. Why? That is because libertarianism, properly understood, is a theory of intra-human rights; this philosophy says nothing about right from an extra-human perspective, Heumer to the contrary notwithstanding. That is to say, he is improperly (...) importing into the freedom philosophy considerations extraneous to it. (shrink)

During the past thirty years, scholars and commentators have produced a flood of articles and books on almost every aspect and feature of Berkeley's work. There are, however, very few points on which these commentators agree. Since the debate shows no signs of abating, Walter Creery has gathered together a collection of the more significant articles in this extremely useful and accessible form. These three volumes gather together eighty-seven articles on Berkeley's views on the central issues of the philosophy (...) of language, the theory of vision, qualities, general ideas, matter, the theory of mind, and notions. The collection contains articles both harshly critical of Berkeley as well as those sympathetic with the philosopher's views, and there has been an attempt to balance the selection between the immaterialist and idealist theories.

SummaryThe problems of operations research, optimized at the tactical and strategic level, have a domain of interest much broader than many of its earlier suboptimization problems. Its appeal to scientific method requires the construction of a model from which predictions can be made. This model must have the comprehensive character of those proposed by philosophy and the sciences. Such a model is available in the form of war gaming, a traditional military training vehicle transformed in such a way as to (...) make it a research tool of great power and flexibility and which can assume a multitude of forms. The war game as a new research tool, when applied to the important problems at a high level of optimization, carries with it the excitement of a pioneering venture and the promise of contributions of greatly increased importance to the development of military science.

In light of recent advances, I reconsider Jacques Ellul's technological imperative in which he places technology in a broad framework of “technique” (including but not limited to machines) meaning any complex of standardized procedures having absolute efficiency for attaining a predetermined result. He conceptualizes technique as a self-perpetuating, totalizing, and deterministic force inevitably leading to self-destruction if not transcended. Here, I provide support for some of Ellul's claims while addressing some of the important criticisms. I suggest a different kind of (...) imperative that supersedes the technological imperative but does not diminish its importance. The new imperative is hierarchical social structures that now prevail at many levels—from global to local—and that reciprocally relate to many social forces, including technique. Central to the maintaining of social hierarchies are both individual and collective goals and beliefs. I argue the importance of ideology in both science and society, and in technological and hierarchical imperatives. Specifically, I argue the necessity to account for the mutual and reciprocal relationship among beliefs, context, and human attributes to fully comprehend technology and education. (shrink)

Erik Erikson's work in psychosocial developmental theory has made valuable contributions to the field of religious ethics on some very basic issues. This paper makes scattered elements of Erikson's explicit ethical perspective available in concise fashion for critical ethical reflection. It does this in such a way as to highlight the centrally important fact for religious ethics that implicitly operative in Erikson's view is a criterion of "self-transcendence" as definitive of mature personal (fully human, ethical) development.

The defense argument in favor of abortion sees the fetus as an invader, a trespasser, someone against whom violence is justified, since this very young person (the fetus) has initiated violence against his mother. Hewitt [30] rejects this argument. The present paper maintains the justification of this defense argument. My perspective is based on the private property rights of the mother. She owns her person. It is as if her body is her house, and a trespasser has invaded it. Surely, (...) she has the right to evict such a person. This analogy is relatively easy to see in the case of rape. The unwanted fetus, now occupying a part of her body is in effect a intruder. If she really owns her body, which I contend she certainly does, she has a right to expel this person from her property. I also argue that voluntary sexual intercourse does not constitution an “invitation” for the pre-born baby to occupy her premises for nine months. (shrink)

The present article is a continuation of the debate two sets of authors have been engaging in regarding one type of maturity mismatching: borrowing short and lending long. All four authors had agreed that this practice can set up the Austrian Business Cycle; the present author denies that BSLL would be a legitimate commercial interaction in the free society; Bagus and Howden continue to maintain that it would be licit. Our main criticism of Bagus and Howden is a reductio ad (...) absurdum: that this opens them up to the charge of embracing the doctrine of market failure; this is something highly problematic for the two of them, since all four contributors to this debate are well-known supporters of laissez faire capitalism.
