A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

Thomas S. Kuhn's classic book is now available with a new index.

The definitions of ‘negative knowledge’ and the studies in this regard published to date have not considered the categorial distinction Wittgenstein established between knowledge and certainty. Hence, the important role that certainty, despite its omission, should have in these definitions and studies has not yet been shown. In this article, I contrast the term ‘negative certainty’ with that of ‘negative knowledge’ in order to clarify this concept by describing its significant differences with the first. To characterize negative certainty, I base (...) upon two criteria: on the one hand, negative certainty cannot be directly excluded by a positive certainty, and on the other hand, negative certainty must have an obvious and practical usefulness in which its negative nature is clearly appreciated. To illustrate the use of these two criteria, I describe four examples of negative certainty, paying special attention to their educational implications as well as the contrast between negative certainty and negative knowledge.

In Descartes's Meditations, one of the key texts of Western philosophy, the thinker rejects all his former beliefs in the quest for new certainties. Discovering his own existence as a thinking entity in the very exercise of doubt, he goes on to prove the existence of God, who guarantees his clear and distinct ideas as a means of access to the truth. He develops new conceptions of body and mind, capable of serving as foundations for the new science of nature. (...) Subsequent philosophy has grappled with Descartes's legacy, questioning many of its conclusions and even his basic approach, but his arguments set the agenda for many of the greatest philosophical thinkers, and their fascination endures.This new translation includes the Third and Fourth Objections and Replies in full, and a selection from the rest of Descartes's exchanges with contemporaries that helped to shape and expound his philosophy.

The Meditations, one of the key texts of Western philosophy, is the most widely studied of all Descartes' writings. This authoritative translation by John Cottingham, taken from the much acclaimed three-volume Cambridge edition of the Philosophical Writings of Descartes, is based upon the best available texts and presents Descartes' central metaphysical writings in clear, readable modern English. As well as the complete text of the Meditations, the reader will find a thematic abridgement of the Objections and Replies (which were originally (...) published with the Meditations) containing Descartes' replies to his critics. These extracts, specially selected for the present volume, indicate the main philosophical difficulties which occurred to Descartes' contemporaries and show how Descartes developed and clarified his arguments in response. This edition contains a new comprehensive introduction to Descartes' philosophy by John Cottingham and the classic introductory essay on the Meditations by Bernard Williams. (shrink)

Wittgenstein scholars have tended to interpret the acquisition of certainties, and by extension, of a world-picture, as the achievement of a state in which these certainties are assimilated in a seemingly unconscious way as one masters language-games. However, it has not been stressed that the attainment of this state often involves facing a series of challenges or difficulties which must be overcome for the development of the world-picture and therefore the socialization process to be achieved. After showing, on the one (...) hand, how a world-picture is usually developed, and on the other hand, why a child who seemingly found itself trapped in a precocious skepticism might have serious problems in assimilating certainties, in this paper, I describe some of the challenges children often meet as they acquire a world-picture. Since the overcoming of these challenges is often needed for children to develop a world-picture, I aim at raising the awareness of the necessity of ‘learning to believe’, that is, of developing a series of skills that allow children to undertake the challenges described in this paper.

Though Wittgenstein's On Certainty has been influential in analytic epistemology, its interpretation has been enormously controversial. It is true that exegesis has been mainly concerned with the proper characterization of Wittgenstein's very notion of ?certainty?; however, some important questions remain unanswered regarding this notion. On the one hand, I am above all referring to the study of the possibilities we have of retaining a certainty when it has seemingly been placed into question and, on the other hand, of regaining a (...) certainty once it has been lost. In this paper, I attempt to provide a detailed answer to both questions. In so doing, some important features of the picture of ourselves which emerges from Wittgenstein's On Certainty are also revealed. (shrink)

Zettel, an en face bilingual edition, collects fragments from Wittgenstein's work between 1929 and 1948 on issues of the mind, mathematics, and language.

After describing Wittgenstein's notion of ‘certainty’, in this article I provide four arguments to demonstrate that no certainty can be acquired at will. Specifically, I argue that, in order to assimilate a certainty, it is irrelevant whether the individual concerned has found a ground that seemingly justifies that certainty; has a given mental state; is willing to accept the certainty on the proposal of a persuader; or tries to act according to the certainty involved. Lastly, I analyse how each of (...) these arguments is reflected in the way children acquire certainties. (shrink)

This book comprises material on colour which was written by Wittgenstein in the last eighteen months of his life. It is one of the few documents which shows him concentratedly at work on a single philosophical issue. The principal theme is the features of different colours, of different kinds of colour (metallic colour, the colours of flames, etc.) and of luminosity—a theme which Wittgenstein treats in such a way as to destroy the traditional idea that colour is a simple and (...) logically uniform kind of thing. This edition consists of Wittgenstein's basic German text, together with an English translation. (shrink)

This chapter discusses evidence for the claim that the protodraft was written prior to MS 139a and that MS 139b is the text that Wittgenstein read when he gave his talk. It begins with some introductory remarks about the transcriptions of the four versions. The chapter discusses the time relation between versions and present textual evidence that the proto‐draft was written prior to MS 139a. It discusses on the claim that MS 139b is the text of Wittgenstein's lecture.
