How Classification Works attempts to bridge the gap between philosophy and the social sciences using as a focus some of the work of Nelson Goodman. Throughout his long career Goodman has addressed the question: are some ways of conceptualizing more natural than others? This book looks at the rightness of categories, assessing Goodman's role in modern philosophy and explaining some of his ideas on the relation between aesthetics and cognitive theory. Two papers by Nelson Goodman are included in (...) the collection and there are analyses of his work by seven leading academics in anthropology, philosophy, sociology and musicology. (shrink)

How do economists persuade their readers that one policy is superior to another? A glance at the literature on welfare economics quickly provides the answer to this question: Economists enter policy debates armed with mathematical models, evaluating options on the basis of their consequences. Economists typically classify a policy change as a welfare improvement with respect to the status quo if the gain realized by the winners exceeds the harm sustained by the losers. The best policy becomes the one that (...) generates the highest net benefit. (shrink)

Originally published in 1995 this is the fifth volume in the series Creationism in 20th Century America. It re-publishes After Its Kind - a critique on theories of biological evolution and a defense of the biblical account of creation which Nelson wrote when he was a Pastor in New Jersey where he also attended classes in genetics and zoology at Rutgers university. His 1931 volume The Deluge Story in Stone: A History of the Flood Theory of Geology, also reprinted (...) here was continuously in print until the 1960s. As his scientific and theological correspondence expanded in the wake of his publications, Nelson became further involved in the 'evolution debates'. During the late 1930s his writings concentrated on early man and the glacial phenomena he saw all about him in Wisconsin and he compiled the materials he thought necessary to relate Scripture to the evidence of human antiquity.

The Clarke/Rowe version of the Cosmological Argument is sound only if the Principle of Sufficient Reason is true, but many philosophers, including Rowe, think that there is not adequate evidence for the principle of sufficient reason. I argue that there may be indirect evidence for PSR on the grounds that if we do not accept it, we lose our best justification for an important principle of metaethics, namely, the Principle of Universalizability. To show this, I argue that all the other (...) justifications of the Principle of Universalizability on offer, including Richard Hare's, are inadequate. (shrink)

This article is not intended to state what I positively believe to be true, but to make a suggestion which I think it well-worth working out. The suggestion is not altogether unfamiliar, but it has certain implications that seem to have been so far overlooked, or at any rate have never been developed. I do not think that it is the duty of a philosopher to confine himself in his publications to working out theories of the truth of which he (...) is convinced.… It is a part of a philosopher's work, as it is of a scientist's, to try out tentative hypotheses and examine their advantages and disadvantages.

Nelson Goodman's acceptance and critique of certain methods and tenets of positivism, his defence of nominalism and phenomenalism, his formulation of a new riddle of induction, his work on notational systems, and his analysis of the arts place him at the forefront of the history and development of American philosophy in the twentieth-century. However, outside of America, Goodman has been a rather neglected figure. In this first book-length introduction to his work Cohnitz and Rossberg assess Goodman's lasting contribution to (...) philosophy and show that although some of his views may be now considered unfashionable or unorthodox, there is much in Goodman's work that is of significance today. The book begins with the "grue"-paradox, which exemplifies Goodman's way of dealing with philosophical problems. After this, the unifying features of Goodman's philosophy are presented - his constructivism, conventionalism and relativism - followed by an discussion of his central work, The Structure of Appearance and its significance in the analytic tradition. The following chapters present the technical apparatus that underlies his philosophy, his mereology and semiotics, which provides the background for discussion of Goodman's aesthetics. The final chapter examines in greater depth the presuppositions underlying his philosophy. (shrink)

ExtractThe logical Law of Non-contradiction – that a proposition cannot be both true and false – enjoys a special, perhaps uniquely privileged, status in philosophy. Most philosophers think that finding a contradiction – the assertion of both P and not-P – in one's reasoning is the best possible evidence that something has gone wrong, the ultimate refutation of a position. But why should this be so? What reason do we have to believe it?Send article to KindleTo send this article to (...) your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

Henry Nelson Wieman and Reinhold Niebuhr were theologically poles apart—Wieman a “new naturalist” and Niebuhr a “new super naturalist”—according to Wieman's nomenclature. Wieman devoted more time and attention to Niebuhr than Niebuhr did to him. The reason for this was the result of Wieman's sustained attack on the “new supernaturalism” with which he identified Niebuhr as one of the major American representatives. This article traces the background to Wieman's view of Niebuhr—Wieman's own views on science, on religion, and on (...) Christianity—then proceeds to Wieman's analysis of Niebuhr's theology and his relation to the “new supernaturalism,” concluding with Niebuhr's reply to Wieman. (shrink)

Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity limits (...) will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed. Key Words: attention; enumeration; information chunks; memory capacity; processing capacity; processing channels; serial recall; short-term memory; storage capacity; verbal recall; working memory capacity.

Nelson's Proof of the Impossibility of the Theory of Knowledge -/- In addressing the possibility of a theory of knowledge, Leonard Nelson noted the contradiction of an epistemological criterion that one would require in order to differentiate between valid and invalid knowledge. Nelson concluded that the inconsistency of such a criterion proves the impossibility of the theory of knowledge. -/- Had the epistemological criterion had a perception, then it would presume to adjudicate on its own truth (thus (...) epistemological circular argument). However, if one were to assume that the criterion is not knowledge, one would then have to justify how this is a criterion for truth - yet this would only be possible when it may be considered as an object of knowledge. One would equally have had to predetermine the criterion in order to determine the truth of this knowledge, thereby providing another circular argument. Ostensibly, every criterion of truth fails at its very own test since it cannot guarantee its own truth, just as Munchausen, contrary to his assertion, could not draw himself out of the swamp by tugging on a tuft of his own hair. -/- Nelson proposed a solution of the epistemological problem (the question of the differentiation between valid and invalid knowledge), that based on Jakob Friedrich Fries' differentiation between proof and deduction. Proof, according to Nelson (in reference to Fries), can be defined as derivation of truth from one statement from another statement. Thus, from the truth in the statement that "all men are mortal", one is then able to say that "Socrates is a man" and thence extrapolate from the truth of the statement that "Socrates is mortal." If knowledge were to be considered somewhat judgmental (in a statement), then an attempt at proof (i.e. recourse to previous judgments) would inevitably lead to an infinite regression in justification, since each judgment would necessitate a further justification from another judgment. Every attempt to prove an epistemological criterion is thus also confronted by this regression in justification. -/- Nelson's attempt at a solution rests on the assumption of the existence of an immediate knowledge as a justification of the truth (mediate) of knowledge. Nelson considers immediate knowledge to be non-judgmental knowledge. These include intuitions (e. g. seeing-the-red-roof) and also philosophical knowledge that pre-exists in his opinion before a judgmental reflexion (immediate) in our reason (e. g. the principle of causality). -/- Proof of the truth of mediate knowledge can be effected by showing its compliance with attendant immediate knowledge (rational truth = correspondence of mediate knowledge with their immediate knowledge). Nelson considered this as a resolution of the circular epistemological argument. In regard to philosophical knowledge, Nelson sees these as subject to deduction and not proof. The following example illustrates the goal of deduction: -/- An approach for deducing the principle of causality: A) Every change has a cause. (The principle of causality) A´) A is a reiteration of an immediate knowledge. (Meta-assertion following A) -/- "A" may not be provable, but A´ may justified, and thus Nelson identified it as a deduction following from A. // reference: http://www.friesian.com/nelproof.htm.

The main aim of the present paper is to explain a nature of relationships exist between Nelson and Heyting algebras. In the realization, a topological duality theory of Heyting and Nelson algebras based on the topological duality theory of Priestley for bounded distributive lattices are applied. The general method of construction of spaces dual to Nelson algebras from a given dual space to Heyting algebra is described. The algebraic counterpart of this construction being a generalization of the (...) Fidel-Vakarelov construction is also given. These results are applied to compare the equational category N of Nelson algebras and some its subcategories with the equational category H of Heyting algebras. It is proved that the category N is topological over the category H. (shrink)

Leonard Nelson is known primarily as a critic of epistemology in the Neo-Kantian meaning of the term. The aim of this paper is to investigate the presuppositions and consequences of his critique. I claim that what has rarely been discussed in this context is the problem of the possibility of metaphysics. By the impossibility of epistemology Nelson means the possibility of metaphysical knowledge. I intend to devote this paper to the analysis of this problem in relation to the (...) Neo-Kantian background. (shrink)

With this third edition of Nelson Goodman's The Structure of Appear ance, we are pleased to make available once more one of the most in fluential and important works in the philosophy of our times. Professor Geoffrey Hellman's introduction gives a sustained analysis and appreciation of the major themes and the thrust of the book, as well as an account of the ways in which many of Goodman's problems and projects have been picked up and developed by others. Hellman (...) also suggests how The Structure of Appearance introduces issues which Goodman later continues in his essays and in the Languages of Art. There remains the task of understanding Good man's project as a whole; to see the deep continuities of his thought, as it ranges from logic to epistemology, to science and art; to see it therefore as a complex yet coherent theory of human cognition and practice. What we can only hope to suggest, in this note, is the b. road Significance of Goodman's apparently technical work for philosophers, scientists and humanists. One may say of Nelson Goodman that his bite is worse than his bark. Behind what appears as a cool and methodical analysis of the conditions of the construction of systems, there lurks a radical and disturbing thesis: that the world is, in itself, no more one way than another, nor are we. It depends on the ways in which we take it, and on what we do. (shrink)

This book is a philosophical exploration of the theoretical causes behind the collapse of classical cybernetics. Alcibiades Malapi-Nelson advances the idea that the cybernetic understanding of the nature of a machine entails ontological and epistemological consequences that create both material and theoretical conundrums. He proposes that, given our current state of materials, research, and practices, there might be a way for cybernetics to flourish. The book starts with a historical treatment of cybernetics, and proceeds with a philosophical explanation of (...) its collapse-emphasizing the work of Turing, Ashby and von Neumann-and connects it with the emerging technologies carrying its signature. The transhumanist metaphysics of both cybernetics and NBIC is then unveiled. Finally, avenues of research that may allow these technologies to circumvent the cybernetic fate are indicated. It is advanced that emerging technologies ultimately entail an affirmation of humanity. (shrink)

In this paper I attempt to capture the essence of Nelson Pike’s contribution to the philosophy of religion. My summary of his insights will revolve around three general topics: omniscience (and in particular its relation to human freedom), omnipotence (and in particular its relation to the existence of human suffering), and mysticism (with a focus on the question of whether and in what sense mystic visions can be sources of knowledge). Although the details vary in interesting ways, his work (...) on these topics largely consists of recognizing an important challenge to the viability of the relevant doctrine or framework, sharpening that challenge by presenting it in a more forceful way, and then offering and assessing potential responses. Pike’s writings are characterized by exemplary rigor and relentless clarity, and together they constitute a rich (and under-appreciated) source of insight. (shrink)

Die kritische Auseinandersetzung mit zeitgenössischen Strömungen der Philosophie nahm in Nelsons Lehrtätigkeit und Veröffentlichungen breiten Raum ein. Neben konkurrierenden Ausprägungen des Neukantianismus grenzte er sich gegen Pragmatismus, Positivismus und die phänomenologische Schule ab, vor allem aber auch gegen Autoren wie Bergson und Spengler, die einem Paradigma von Philosophie verpflichtet waren, das Nelson in seinen Vorlesungen mit dem Ausdruck "intuitive Philosophie" bezeichnete. Nelsons Kritik beschränkt sich nicht darauf, dieser Art Philosophie Begründungsmängel vorzuwerfen. Vielmehr sieht er die "intuitive Philosophie" in dem (...) klassischen Denkfehler befangen, gehaltvolle Aussagen aus bloßen Begriffen herzuleiten und die Gültigkeit ihrer Thesen durch die fälschliche Berufung auf begriffliche Tatsachen zu erschleichen. Wie für Wittgenstein sind auch Nelsons leitende Ideale in der Philosophie Klarheit und kompromisslose Konsequenz. Wenn irgendwo, dann erweist sich Nelson mit diesem Text als analytischer Philosoph im besten Sinne - als ein Philosoph, für den die "Kunst, zu philosophieren" zuallererst in der Kunst des richtigen Argumentierens besteht und für den diese Kunst insbesondere durch die Analyse der Argumentationen und Fehlargumentationen anderer Philosophen erworben wird.

In his new foreword to this edition, Hilary Putnam forcefully rejects these nativist claims.

Constructive logic with Nelson negation is an extension of the intuitionistic logic with a special type of negation expressing some features of constructive falsity and refutation by counterexample. In this paper we generalize this logic weakening maximally the underlying intuitionistic negation. The resulting system, called subminimal logic with Nelson negation, is studied by means of a kind of algebras called generalized N-lattices. We show that generalized N-lattices admit representation formalizing the intuitive idea of refutation by means of counterexamples (...) giving in this way a counterexample semantics of the logic in question and some of its natural extensions. Among the extensions which are near to the intuitionistic logic are the minimal logic with Nelson negation which is an extension of the Johansson's minimal logic with Nelson negation and its in a sense dual version — the co-minimal logic with Nelson negation. Among the extensions near to the classical logic are the well known 3-valued logic of Lukasiewicz, two 12-valued logics and one 48-valued logic. Standard questions for all these logics — decidability, Kripke-style semantics, complete axiomatizability, conservativeness are studied. At the end of the paper extensions based on a new connective of self-dual conjunction and an analog of the Lukasiewicz middle value ½ have also been considered. (shrink)

David Nelson’s constructive logics with strong negation may beviewed as alternative paraconsistent logic. These logics have been developedbefore da Costa’s works. We address some philosophical aspects of Nelson’slogics and give technical results concerning Kripke models and tableau calculi. We also suggest possible applications of paraconsistent constructivelogics.

Since the time of Hume, many philosophers have thought it impossible to deduce an ‘Ought’ from an ‘Is,’ or in general to deduce ‘ethical sentences’ from purely ‘factual sentences.’ This is the thesis of the logical autonomy of ethics. I consider a more recent argument by Toomas Karmo in support of the autonomism, but show its limitations in the context of justification skepticism about ethics.

Naturwissenschaften, Mathematik und Logik waren für Nelson von zentraler Bedeutung. Er pflegte bereits als Jugendlicher intensive Kontakte zu Naturwissenschaftlern und Mathematikern. Dadurch erhielt er Anregungen, die von Anfang an seine philosophischen Ansätze beeinflussten. Inspiriert von der Kant-Fries’schen Philosophie und der Axiomatik der Mathematik, konzipierte Nelson seine Philosophie als exakte Wissenschaft. Wie Kant und Fries betrachtete Nelson die Suche nach den allgemeinen Prinzipien der Naturwissenschaften als Hauptaufgabe der Naturphilosophie. Ergebnis dieser kritischen Analyse ist ein System von metaphysischen Grundsätzen (...) der Naturwissenschaft. Nelson übernimmt Kants Lehre von den Grundsätzen des reinen Verstandes. Keine empirisch gefundene Gesetzmäßigkeit könne diesen Grundsätzen widersprechen. Für die Gesetze der Newton’schen Mechanik hätten, so meint Nelson, Kant und Fries diesen Nachweis erbracht. Deshalb formulierte Nelson das sogenannte Postulat der Mechanistik, gemäß dem alle Naturerscheinungen auf mechanische Vorgänge zurückgeführt werden können. Das starre Festhalten an diesem Postulat veranlasste ihn zur Ablehnung bedeutsamer physikalischer Konzeptionen (z. B. des auf der Elektrodynamik basierenden Relativitätsprinzips, des Nahwirkungskonzepts und des Atommodells). Das „Relativitätsprinzip der Elektrodynamik“ lehnte er mit dem Argument ab, es verhindere die Anwendung der dritten Analogie der Erfahrung, da es den Verzicht auf den Begriff der Gleichzeitigkeit von Naturerscheinungen erzwinge. Eine kritische Nelson-Rezeption muss der Historizität etlicher Thesen Nelsons Rechnung tragen, aber zugleich die Bedeutsamkeit von Kernaussagen Nelson’scher Naturphilosophie im Hinblick auf die modernen Naturwissenschaften untersuchen. Das ist auch die Zielrichtung des vorliegenden Beitrages. Der erste Teil beleuchtet Nelsons wissenschaftliches Umfeld. Einerseits wird untersucht, welche Wissenschaftler Nelson beeinflussten, andererseits soll dargestellt werden, welcher Personenkreis an der Fortentwicklung der Nelson’schen Naturphilosophie beteiligt war. Beispielhaft sollen daran anschließend zwei Themenbereiche aus seinem reichhaltigen Werk disktiert werden, denen besonders im Hinblick auf aktuelle philosophische Diskussionsschwerpunkte Bedeutsamkeit zukommt. Im zweiten Teil werden nämlich Nelsons Betrachtungen zum Verhältnis von Freiheit und Naturnotwendigkeit sowie seine Unterscheidung zwischen wissenschaftlicher und ästhetischer Naturbetrachtung besprochen. Der Beitrag beansprucht nicht, die Rezeptionssgeschichte und den Inhalt von Nelsons Naturphilosophie sowie die aktuelle Bedeutsamkeit seiner Thesen im Detail darzustellen aufzuarbeiten. Vielmehr geht es darum, Ansätze für eine zeitgemäße Interpretation Rezeption aufzuzeigen und anhand von Beispielen zu erörtern. (shrink)
