Originally published in 1938. This compact treatise is a complete treatment of Aristotle’s logic as containing negative terms. It begins with defining Aristotelian logic as a subject-predicate logic confining itself to the four forms of categorical proposition known as the A, E, I and O forms. It assigns conventional meanings to these categorical forms such that subalternation holds. It continues to discuss the development of the logic since the time of its founder and address traditional logic as it existed in the twentieth century. The primary consideration of the book is the inclusion of negative terms - obversion, contraposition etc. – within traditional logic by addressing three questions, of systematization, the rules, and the interpretation.

"Although most natural law ethical theories recognize moral absolutes, there is not much agreement even among natural law theorists about how to identify them. The author argues that in order to understand and determine the morality (or immorality) of a human action, it must be considered in relation to the organized system of human practices within which it is performed. Such an approach, he argues, is to be found in the natural law theory of Thomas Aquinas, especially once it is recognized that the logical structure of Aquinas's ethical theory is basically that of an Aristotelian science." "The book will be useful to students and scholars interested in ethics, especially from an Aristotelian and/or Thomistic perspective. One appendix reproduces the Leonine text of the De malo (question 6), with facing English translation. Another appendix provides facing Latin text and English translation of the Summa Theologiae I-II (question 94, article 2)."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Symbolic logic may be superior to classical Aristotelian logic for the sciences, but not for the humanities. This text is designed for do-it-yourselfers as well as classrooms.

Aristotle was the first and one of the greatest logicians. He not only devised the first system of formal logic, but also raised many fundamental problems in the philosophy of logic. In this book, Dr Lear shows how Aristotle's discussion of logical consequence, validity and proof can contribute to contemporary debates in the philosophy of logic. No background knowledge of Aristotle is assumed.

The impact of Aristotle cannot be overestimated, covering not only the "first philosophy", which later was to become "metaphysics", but several different areas, ranging from ethics and politics to rhetoric and poetry. A special status belongs to the fundamentals of thinking, treated in the logical writings. Another core of Aristotelian philosophy concerns the philosophy of nature - issues of life and soul, natural kinds, animal movement, nature in all its aspects, including the translunar sphere of heavenly bodies. The psychology of De anima is part of this philosophy of nature, but at the same time includes a noetic sphere, indicating another dimension of human life, which enables true knowledge and truly virtuous actions. These aspects of Aristotelian philosophy are often studied separately. While there are several important works on Aristotelian logic, ethics and psychology, the aim of the current volume is to offer perspectives on the interrelatedness of these domains.

Aristotle, according to the author, depicts the way in which human acts of various sorts and in various combinations determine the logical structure of moral character. Some moral characters--or character types--manage to incorporate a high degree of practical consistency; others incorporate less, without forfeiting their basic orientation toward the good. Still others approach utter inconsistency or moral deprivation, although even these, insofar as they are responsible for their actions, retain a core element of rationality in their souls. According to Aristotle, moral character depends ultimately on the structure of individual acts and on how they fit together into a whole that is consistent--or not consistent--with justice and friendship.--From publisher's description.
