Naming and Necessity


Saul A. Kripke - 1980
    It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of reference, in particular of naming, and of identity. From a critique of the dominant tendency to assimilate names to descriptions and more generally to treat their reference as a function of their Fregean sense, surprisingly deep and widespread consequences may be drawn. The largely discredited distinction between accidental and essential properties, both of individual things (including people) and of kinds of things, is revived. So is a consequent view of science as what seeks out the essences of natural kinds. Traditional objections to such views are dealt with by sharpening distinctions between epistemic and metaphysical necessity; in particular by the startling admission of necessary a posteriori truths. From these, in particular from identity statements using rigid designators whether of things or of kinds, further remarkable consequences are drawn for the natures of things, of people, and of kinds; strong objections follow, for example to identity versions of materialism as a theory of the mind.This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here published with a substantial new Preface by the author.

Chess: How to Play Chess: For (Absolute) Beginners: The Journey to Your Empire Begins Here


Maxen Tarafa - 2015
     Many Chess books for beginners will overload you with information about openings, tactics, forks, history, notation, and lot of other things beginners don’t need to know and don’t understand. That might work for some people. But in this highly anticipated prequel to the Conquer your Friends series, I’m going to SHOW you how you can play the game of Chess AND WIN in a heinously short amount of time. Hi, my name is Maxen Tarafa, and I’m a Skill Artist. Most teachers struggle to show beginners how to play Chess because they forget what it’s like to start from the beginning. I specialize in working with beginners, post-beginners, and casual players, and now I’ve broken down the specific needs of the (absolute) beginner. You see, I believe Chess belongs to regular people who enjoy playing Chess with their friends or at home, not in the hands of “experts” who use incomprehensible terminology and notation. After working with several beginners, I realized their greatest struggle is not just remembering how the pieces move, but seeing the board beyond where the pieces physically sit. I’m going to show you how to play Chess using step-by-step images with arrows and interactive exercises Who is this book for? Perhaps, you’ve never played Chess but you’ve always wanted to learn and never had the chance. Or maybe, you’ve already learned how to move the pieces, but you need an easy, straight-forward refresher. Or perhaps, it’s time to show your son or younger brother how to play Chess and you want to review the basics, so you can make sure you nail the questions beginners commonly miss. Whether you’re brand new to Chess or you just want to pass the tradition down, this book is for you. In this book, you’ll learn how to: Quickly and confidently move each piece from Pawn to King Set up the board from memory quickly and correctly every…single…time Use my step-by-step method for commanding the puzzling Knight Harness the power of your own mind to visualize the board and gain an edge over your opponent Learn the little-known reason why most beginners lose and how to use it to your advantage Employ a three-question checklist to ensure you don’t lose your pieces for no good reason Blow your opponent’s mind! Predict your opponent’s strategy three moves ahead and stop their plan before they’ve even tried it I’ve taught beginner Chess players from age 5 to age 35 and beyond, anyone can learn and now’s your chance to finally learn the ancient game of Kings and Conquerors! Don’t miss your chance! Join the casual Chess revolution today!

An Introduction to Non-Classical Logic


Graham Priest - 2001
    Part 1, on propositional logic, is the old Introduction, but contains much new material. Part 2 is entirely new, and covers quantification and identity for all the logics in Part 1. The material is unified by the underlying theme of world semantics. All of the topics are explained clearly using devices such as tableau proofs, and their relation to current philosophical issues and debates are discussed. Students with a basic understanding of classical logic will find this book an invaluable introduction to an area that has become of central importance in both logic and philosophy. It will also interest people working in mathematics and computer science who wish to know about the area.

On Truth


Harry G. Frankfurt - 2006
    Frankfurt turns to what lies beyond them: the truth, a concept not as obvious as some might expect.Our culture's devotion to bullshit may seem much stronger than our apparently halfhearted attachment to truth. Some people (professional thinkers) won't even acknowledge "true" and "false" as meaningful categories, and even those who claim to love truth cause the rest of us to wonder whether they, too, aren't simply full of it. Practically speaking, many of us deploy the truth only when absolutely necessary, often finding alternatives to be more saleable, and yet somehow civilization seems to be muddling along. But where are we headed? Is our fast and easy way with the facts actually crippling us? Or is it "all good"? Really, what's the use of truth, anyway?With the same leavening wit and commonsense wisdom that animates his pathbreaking work "On Bullshit," Frankfurt encourages us to take another look at the truth: there may be something there that is perhaps too plain to notice but for which we have a mostly unacknowledged yet deep-seated passion. His book will have sentient beings across America asking, "The truth—why didn't I think of that?"

Introduction to Logic: and to the Methodology of Deductive Sciences


Alfred Tarski - 1993
    According to the author, these trends sought to create a unified conceptual apparatus as a common basis for the whole of human knowledge.Because these new developments in logical thought tended to perfect and sharpen the deductive method, an indispensable tool in many fields for deriving conclusions from accepted assumptions, the author decided to widen the scope of the work. In subsequent editions he revised the book to make it also a text on which to base an elementary college course in logic and the methodology of deductive sciences. It is this revised edition that is reprinted here.Part One deals with elements of logic and the deductive method, including the use of variables, sentential calculus, theory of identity, theory of classes, theory of relations and the deductive method. The Second Part covers applications of logic and methodology in constructing mathematical theories, including laws of order for numbers, laws of addition and subtraction, methodological considerations on the constructed theory, foundations of arithmetic of real numbers, and more. The author has provided numerous exercises to help students assimilate the material, which not only provides a stimulating and thought-provoking introduction to the fundamentals of logical thought, but is the perfect adjunct to courses in logic and the foundation of mathematics.

Science and Sanity: An Introduction to Non-Aristotelian Systems and General Semantics


Alfred Korzybski - 1933
    

The Nature of Necessity


Alvin Plantinga - 1974
    The arguement is developed by means of the notion of possible worlds and ranges over key problems including the nature of essence, trans-world identity, negative existential propositions, and the existence of unactual objects in other possible worlds. In the final chapters Professor Plantinga applies his logical theories to the elucidation of two problems in the philosophy of religion: the Problem of Evil and the Ontological Arguement. The first of these, the problem of reconciling the moral perfection and omnipotence of God with the existence of evil, can, he concludes, be resolved, and the second given a sound formulation. The book ends with an appendix on Quine's objection to quantified modal logic.
