Syllogisms with fractional quantifiers

Includes bibliographical references (page 422).Aristotle's syllogistic is extended to include denumerably many quantifiers such as more than 2/3' and exactly 2/3'. Syntactic and semantic decision procedures determine the validity, or invalidity, of syllogisms with any finite number of premises. One of the syntactic procedures uses a natural deduction account of deducibility, which is sound and complete. The semantics for the system is non-classical since sentences may be assigned a value other than true or false. Results about symmetric systems are given. And reasons are given for claiming that syllogistic validity is relevant validity

Towards an authentic argumentation literacy test

A central goal of education is to improve argumentation literacy. How do we know how well this goal is achieved? Can we measure argumentation literacy? The present study is a preliminary step towards measuring the efficacy of education with regards to argumentation literacy. Tests currently in use to determine critical thinking skills are often similar to IQ-tests in that they predominantly measure logical and mathematical abilities. Thus, they may not measure the various other skills required in understanding authentic argumentation. To identify the elements of argumentation literacy, this exploratory study begins by surveying introductory textbooks within argumentation theory, critical thinking, and rhetoric. Eight main abilities have been identified. Then, the study outlines an Argumentation Literacy Test that would comprise these abilities suggested by the literature. Finally, the study presents results from a pilot of a version of such a test and discusses needs for further development

Civilization and Progress

Historical and systematic in its treatment, this work reviews the idea of progress in Western thought as it relates to civilization, in a more comprehensive survey than is to be found in previous writings on the subject. In the author’s view, the history of civilization reveals an increasing range of human capacity, both for good and for evil, depending upon men’s choice between contending values. From this standpoint, the work proceeds to the exploration of such fields of social activity as the evolution of the family, the emancipation of women, economic conditions and technology, intellectual and aesthetic values, moral and religious experience. Civilization and Progress is marked by balanced and judicious treatment, very broad learning, and a lucid and forceful style. The author asks us to consider the alternatives we face and to reflect on the choices which men have made in the past, which confront us in the present world crisis, and on which our destiny hangs in the future. Seminal in scholarship and creativity, this work will interest those concerned with the Western intellectual tradition and with the condition of mankind. Radoslav A. Tsanoff is the author of numerous books on philosophy. He is McManis Professor of Philosophy at Rice University.https://uknowledge.uky.edu/upk_philosophy/1003/thumbnail.jp

Three-membered domains for Aristotle's syllogistic

The paper shows that for any invalid polysyllogism there is a procedure for constructing a model with a domain with exactly three members and an interpretation that assigns non-empty, non-universal subsets of the domain to terms such that the model invalidates the polysyllogism

The other as the essence of existence: a journal of a philosophical passage to altruism

This research is about altruism. In our first chapter, our quest to find whether we are essentially altruistic starts with questioning particular ways of inquiry and proposes a philosophy of unbracketing. In our second chapter, we realise that our proposal starts with an imperative – a prescription. We begin by meditating on the phenomenon of prescription which seems to precede all ways of inquiry. Our analysis of prescription reveals that altruism is to prescribe oneself towards an Other. This type of prescription is to promise a future for an Other. To promise is to give one’s word and to undertake to realising it. In our third chapter, we explore the act of “giving one’s word.” To give one’s word is beyond a speech act. In fact, it is to give one’s logos. An altruistic attempt is carried out in this chapter to liberate ‘logos’ from particular conceptions and allow for its universal meaning to emerge. Logos is traced back to its inceptual conception as existence or will to power – a will to future. This philosophical excavation leads us to our fourth chapter where we re-encounter our original paradox. That is, while human reality starts with a promise of helping someone to make sense – to understand – we have been trying to understand understanding, or how we make sense, by removing the Other and by focusing only on subjective conditions. In this chapter, we reveal how to understand an Other is an altruistic act. In our final chapter, we carefully observe that human existence is a gift from the Other. We describe this gift as a metaphysical passage from being to existence – an altruistic act. A passage which is created by an Other who promises to give us the means to be able to create meaning, that is to say, to exist
