This paper develops an order-theoretic generalization of Blok and Pigozziʼs notion of an algebraizable logic. Unavoidably, the ordered model class of a logic, when it exists, is not unique. For uniqueness, the definition must be relativized, either syntactically or semantically. In sentential systems, for instance, the order algebraization process may be required to respect a given but arbitrary polarity on the signature. With every deductive filter of an algebra of the pertinent type, the polarity associates a reflexive and transitive relation (...) called a Leibniz order, analogous to the Leibniz congruence of abstract algebraic logic . Some core results of AAL are extended here to sentential systems with a polarity. In particular, such a system is order algebraizable if the Leibniz order operator has the following four independent properties: it is injective, it is isotonic, it commutes with the inverse image operator of any algebraic homomorphism, and it produces anti-symmetric orders when applied to filters that define reduced matrix models. Conversely, if a sentential system is order algebraizable in some way, then the order algebraization process naturally induces a polarity for which the Leibniz order operator has properties –.

In this article I defend an account of Meteorology IV as providing a material-level causal account of the emergence of uniform materials with a wide range of dispositional properties not found at the level of the four elements—the emergence of material complexity. I then demonstrate that this causal account is used in the Generation of Animals and Parts of Animals as part of the explanation of the generation of the uniform parts (tissues) and of their role in providing nonuniform parts (...) (organs) with the dispositional properties needed to fulfill their functions. (shrink)

Kuhn closed the Introduction to The Structure of Scientific Revolutions with what was clearly intended as a rhetorical question: How could history of science fail to be a source of phenomena to which theories about knowledge may legitimately be asked to apply? (Kuhn 1970, 9) This paper argues that there is a more fruitful way of conceiving the relationship between a historical and philosophical study of science, which is dubbed the 'phylogenetic' approach. I sketch an example of this approach, and (...) take a first pass at an abstract characterization of the method. (shrink)

Professor Grene's work on Aristotle is considered under three headings: teleology, form, and reductionism. A picture of Aristotle's philosophy of biology is sketched which stresses three elements: the place of living activity in the teleological account of the development and nature of organic structures; the functional nature of Aristotelian form; and the autonomy of biology as a natural science with its own basic principles. These elements are aspects of Aristotle's approach to biology with which Professor Grene has expressed sympathy.

This volume of essays explores major connected themes in Aristotle's metaphysics, philosophy of nature, and ethics, especially themes related to essence, definition, teleology, activity, potentiality, and the highest good. The volume is united by the belief that all aspects of Aristotle's work need to be studied together if any one of the areas of thought is to be fully understood. Many of the papers were contributions to a conference at the University of Pittsburgh entitled 'Being, Nature, and Life in Aristotle', (...) to honor Professor Allan Gotthelf's many contributions to the field of ancient philosophy; a few are contributions from those who were invited but could not attend. The contributors, all longstanding friends of Professor Gotthelf, are among the most accomplished scholars in the field of ancient philosophy today. (shrink)

The main argument of this paper is that an evaluation of the overall explanatory power of a theory is less problematic and more relevant as an assessment of the state of knowledge than evaluation of statistical explanations of single occurrences in terms of likelihoods that are assigned to explananda.

Perhaps the greatest determinant of individual and societal welfare is who raises children and with what degree of discretion. Philosophers have endeavored in myriad ways to provide normative justification for ascribing a right to be a legal parent and to possess particular legal powers as a parent. This Article shows why they fail and offers an alternative theoretical framework for delimiting parental rights. The prevailing tendency in philosophical writing on the topic is to begin with observations and intuitions specific to (...) parent-child relationships. Against that tendency, this Article demonstrates the need to begin with principles at a high level of generality, covering a broad range of human relationships. This yields a much more limited moral right in connection with parenthood than do accounts that fail to generalize. (shrink)

This paper provides a semantic analysis of admissible rules and associated completeness conditions for arbitrary deductive systems, using the framework of abstract algebraic logic. Algebraizability is not assumed, so the meaning and significance of the principal notions vary with the level of the Leibniz hierarchy at which they are presented. As a case study of the resulting theory, the nonalgebraizable fragments of relevance logic are considered.

This book provides a systematic, inter-disciplinary examination of beliefs in as well as evidence for reincarnation that will appeal to students of anthropology, religious studies, philosophy, and the psychology of consciousness and memory, as well as parapsychology.

Whatever its merits and difficulties, the concept of logic embedded in much of the "new philosophy" of the early modern period was then understood to supplant contemporary views of formal logic. The notion of compiling a natural history of the understanding constituted the basis of this new concept of logic. The following paper attempts to trace this view of logic through some of the major and numerous minor texts of the period, centering on the development and influence of John Locke's (...) understanding of the analysis of the cognitive faculties as the discipline of logic.

Aristotle is without question the founder of the science of biology. In his treatise On the Parts of Animals, he develops his systematic principles for biological investigation, and explanation, and applies those principles to explain why the different animal kinds have the different parts that they do. It is one of the greatest achievements in the history of science. This new translation from the Greek aims to reflect the subtlety and detail of Aristotle's reasoning. The commentary provides help in understanding (...) each argument as well as an integrated account of the goals and methods of the work taken as a whole. (shrink)

A necessary condition for having a revolution named after you is that you are an innovator in your field. I argue that if Charles Darwin meets this condition, it is as a philosopher and methodologist. In 1991, I made the case for Darwin's innovative use of "thought experiment" in the "Origin." Here I place this innovative practice in the context of Darwin's methodological commitments, trace its origins back into Darwin's notebooks, and pursue Darwin's suggestion that it owes its inspiration to (...) Charles Lyell. (shrink)

I can be aware of myself and refer to myself without it being necessary to think of any third-personal characteristics; indeed one may be aware of oneself without having to be aware of anything except oneself. This consideration raises issues in phenomenological ontology of identity, individuation, and substance.

Rising social, political and economic inequality in many countries, and rising protest against it, has seen the restoration of the concept of 'class' to a prominent place in contemporary anthropological debates. A timely intervention in these discussions, this book explores the concept of class and its importance for understanding the key sources of that inequality and of people's attempts to deal with it. Highly topical, it situates class within the context of the current economic crisis, integrating elements from today into (...) the discussion of an earlier agenda. Using cases from North and South America, Western Europe and South Asia, it shows the - sometimes surprising - forms that class can take, as well as the various effects it has on people's lives and societies.

The referent of the transcendental and indexical “I” is present non-ascriptively and contrasts with “the personal I” which necessity is presenced as having properties. Each is unique but in different ways. The former is abstract and incomplete until taken as a personal I. The personal I is ontologically incomplete until it self-determines itself morally. The “absolute Ought” is the exemplary moral self-determination and it finds a special disclosure in “the truth of will.” Simmel's situation ethics is useful for making more (...) precise Husserl's ethical position.
