Inspired by and expanding on a series of lectures presented by Leonard Peikoff, David Harriman presents a fascinating answer to the problem of induction-the epistemological question of how we can know the truth of inductive generalizations.Ayn Rand presented her revolutionary theory of concepts in her book Introduction to Objectivist Epistemology. As Dr. Peikoff subsequently explored the concept of induction, he sought out David Harriman, a physicist who had taught philosophy, for his expert knowledge of the scientific discovery process.Here, Harriman presents the result of a collaboration between scientist and philosopher. Beginning with a detailed discussion of the role of mathematics and experimentation in validating generalizations in physics-looking closely at the reasoning of scientists such as Galileo, Kepler, Newton, Lavoisier, and Maxwell-Harriman skillfully argues that the inductive method used in philosophy is in principle indistinguishable from the method used in physics.

    What do you say when your faith is challenged by those claiming to speak in the name of science or reason? Discerning Truth provides a practical and engaging resource on the use of logic in this critical debate. Filled with anecdotes from both creative examples and real-life illustrations that help clarify logical issues in apologetics. Become skilled at distinguishing sound arguments from emotionally-charged rhetoric. Helps any believer refute evolutionary perspectives. Lisle believes that creationists need to be able to recognize and refute evolutionist arguments, and to do so in a way that both honors God and lines up with the truth of His Word (Eph. 5:1). The role of logic, the study of correct reasoning, is becoming a vanishing skill in our society. Yet it is a vital tool in assisting Christians in assessing the weaknesses in evolutionary thought. Here is the clear and concise guide for every believer in defending your faith in the face of adversity.

    Unlike other logic puzzle books, every puzzle includes statistics - such as the average completion time, the record completion time, and the percentage of people to complete the puzzle - to bring out the competitor in each puzzler and better inform them on how easy or difficult each puzzle is.?Features 200 grid-based logic puzzles?Includes puzzles statistics for added excitement?Ideal for kids and adults

    This accessible and engaging book provides the necessary tools to question and challenge the discourse that surrounds us --- whether in the media, the classroom, or everyday conversation. Additionally, it offers readers a deeper understanding of the foundations of analytical thought. Informal Logical Fallacies: A Brief Guide is a systematic and concise introduction to more than forty fallacies, from anthropomorphism and argumentum ad baculum, to reductionism and the slippery slope argument. With helpful definitions, relevant examples, and thought-provoking exercises, the author guides the reader through the realms of fallacious reasoning and deceptive rhetoric. This is an essential guide to philosophical reflection and clear thinking.

    Logic for Philosophy covers basic approaches to logic (including proof theory and especially model theory); extensions ofstandard logic that are important in philosophy; and some elementary philosophy of logic. Easily accessible to students without extensive mathematics backgrounds, this lucid and vividly written text emphasizes breadth of coverage rather than depth. Featuring numerous exercises, answers, and helpfulhints, it concisely and effectively introduces students to the logic they need to know in order to read contemporary philosophy journal articles.

    

    Van Benthem begins with the basic theories of modal logic, semantics, bisimulation, and axiomatics, and also covers more advanced topics, such as expressive power and computational complexity. The book then moves to a wide range of applications, including new developments in information flow, intelligent agency, and games. Taken together, the chapters show modal logic at the crossroads of philosophy, mathematics, linguistics, computer science, and economics. Most of the chapters are followed by exercises, making this volume ideal for undergraduate and graduate students in philosophy, computer science, symbolic systems, cognitive science, and linguistics.

    This book on different aspects of his work and on subjects in which his ideas have contemporary resonance includes papers from a May 2006 symposium celebrating G�del's centennial as well as papers from a 2004 symposium. Proof theory, set theory, philosophy of mathematics, and the editing of G�del's writings are among the topics covered. Several chapters discuss his intellectual development and his relation to predecessors and contemporaries such as Hilbert, Carnap, and Herbrand. Others consider his views on justification in set theory in light of more recent work and contemporary echoes of his incompleteness theorems and the concept of constructible set.

    Logic underwent a major renaissance beginning in the nineteenth century. Cantor almost tamed the infinite, and Frege aimed to undercut Kant by reducing mathematics to logic. These achievements were threatened by the paradoxes, like Russell's. This ferment generated excellent philosophy (and mathematics) by excellent philosophers (and mathematicians) up to World War II. This book provides a selective, critical history of the collaboration between logic and philosophy during this period. After World War II, mathematical logic became a recognized subdiscipline in mathematics departments, and consequently but unfortunately philosophers have lost touch with its monuments. This book aims to make four of them (consistency and independence of the continuum hypothesis, Post's problem, and Morley's theorem) more accessible to philosophers, making available the tools necessary for modern scholars of philosophy to renew a productive dialogue between logic and philosophy.

    The Adventure of Reason is divided into five main sections: history of logic (from Russell to Tarski); foundational issues (Hilbert's program, constructivity, Wittgenstein, Godel); mathematics and phenomenology (Weyl, Becker, Mahnke); nominalism (Quine, Tarski); semantics (Tarski, Carnap, Neurath). Mancosu exploits extensive untapped archival sources to make available a wealth of new material that deepens in significant ways our understanding of these fascinating areas of modern intellectual history. At the same time, the book is a contribution to recent philosophical debates, in particular on the prospects for a successful nominalist reconstruction of mathematics, the nature of finitist intuition, the viability of alternative definitions of logical consequence, and the extent to which phenomenology can hope to account for the exact sciences.

    It consists of three treatises from one of the greatest logicians of all time: "A General Method in Proofs of Undecidability," "Undecidability and Essential Undecidability in Mathematics," and "Undecidability of the Elementary Theory of Groups."

    The will is the reason ( logos ) of the intellectual soul, which [reason] is within us, inasmuch as it is the faculty belonging to it which is endowed with freedom of action. The will is the mind desiring [some object], and an appetite possessed of intelligence, yearning after that thing which is desired.

    My Daddy's Name Is Donor reveals stunning findings about the lives of adult offspring of sperm donation, one of the most common reproductive technologies and one that has been practiced widely in the United States and around the world for decades.  Based on first-ever representative, comparative study of adults conceived via sperm donation, it discusses how they struggle with the implications of their conception and how they fare worse than their peers raised by biological parents on important outcomes such as depression, delinquency, and substance abuse.  My Daddy's Name Is Donor aims to launch an international debate on ethics, meaning, and practice of donor conception.
