The viability of Schelling’s Philosophy of Identity depends on the maintenance and cultivation of a reciprocal relationship between internal and objective reality. To stay on course Schelling assiduously checked the conceptual answers he derived from subjective thought against the objective measurements of contemporary physics. As the physicists of his day came to question the materiality of light, Schelling conceptualized it as the outer limit of what the intelligence is capable of grasping intuitively. At the same time he criticized Hegel for (...) ignoring knowledge altogether and for propagating a philosophy of ignorance. More than a century later Jacques Derrida recognized this characteristic in Hegel, but drew a contrary conclusion. Where Schelling counseled that rational philosophy should alter course and set sail toward a higher empiricism, Derrida insisted that in pushing rationality beyond its limits Hegel had sprung a trap of incomprehension andindeterminacy from which no one would or could henceforward escape.This essay evaluates the competing claims of Schelling and Derrida in light of the revolutionary advances of twentieth-century physics. Is this work indeed bringing forth a new world the mind qua mind cannot conceive or measure and liberating man from a prior constraint, or are the emerging physical directives of four dimensional space-time and a flat universe themselves possible only within the cloture de la representation where Derrida presumes to detain human kind indefinitely?

ABSTRACTThe worksheets that presumably contained Newton's early development of the fundamental concepts in his Principia have been lost. A plausible reconstruction of this development is presented based on Newton's exchange of letters with Robert Hooke in 1679, with Edmund Halley in 1686, and on some clues in the diagram associated with Proposition 1 in Book 1 of the Principia that have been ignored in the past. A graphical construction associated with this proposition leads to a rapidly convergent method to (...) obtain orbits for central forces, which elucidates how Newton may have have been led to formulate some of his most fundamental propositions in the Principia.

I focus on three preoccupations of recent writings on proof. -/- I. The role and possible effects of empirical reasoning in mathematics. Do recent developments (specifically, the computer-assisted proof of the 4CT) point to something essentially new as regards the need for and/or effects of using broadly empirical and inductive reasoning in mathematics? In particular, should we see such things as the computer-assisted proof of the 4CT as pointing to the existence of mathematical truths of which we cannot have a (...) priori knowledge? -/- 2. The role of formalization in proof. What are the patterns ofinference according to which mathematical reasoning naturally proceeds? Are they of 'local' character (i.e. sensitive to the subject-matter of the reasoning concerned) or 'global' character (i.e. invariant across all subject-matters)? Finally, what if any relationship is there (a) between the patterns of inference manifest in a proof and its explanatory capacity and (b) between explanatory capacity and rigor? -/- 3. Diagrams and their role in mathematical reasoning. What essentially is diagrammatic reasoning, and what is the nature and basis of its usefulness? Can it play a justificative role in the development of mathematical knowledge and, more particularly, in genuine proof? Finally, does the use of diagrammatic reasoning force an adjustment either in our conception of rigor or in our view of its importance? (shrink)

In a rich and thought-provoking paper, Lambros Malafouris argues that taking material culture seriously means to be ‘systematically concerned with figuring out the causal efficacy of materiality in the enactment and constitution of a cognitive system or operation’ (Malafouris 2004, 55). As I understand this view, there are really two intertwined claims to be established. The first is that the things beyond the skin that make up material culture (in other words, the physical objects and artefacts in which cultural networks (...) and systems of human social relations are realized) may be essential to the enactment of, and be partly constitutive of, certain cognitive systems or operations. The consequence of establishing this claim is supposed to be that we have a mandate to recast the boundaries of the mind so as to include, as proper parts of the mind, things located beyond the skin. Thus, in talking about the contribution of the world to cognition, Malafouris (2004, 58) concludes that ‘what we have traditionally construed as an active or passive but always clearly separated external stimulus for setting a cognitive mechanism into motion, may be after all a continuous part of the machinery itself; at least ex hypothesi’. This is the position that, in philosophical circles, is known increasingly as the extended mind hypothesis (Clark & Chalmers 1998; Menary forthcoming). Henceforth I shall refer to this hypothesis as EM. A stock example will help bring the idea into view. Rumelhart et al. (1986) note that most of us solve difficult multiplication problems by using ‘pen and paper’ as an external resource. This environmental prop enables us to transform a difficult cognitive problem into a set of simpler ones, and to temporarily store the results of certain intermediate calculations. For the fan of EM, the distributed combination of this external resource and certain inner psychological processes constitutes a cognitive system in its own right. (shrink)

The paper explains why an ontology of permanent point particles that are individuated by their relative positions and that move on continuous trajectories as given by a deterministic law of motion constitutes the best solution to the measurement problem in both quantum mechanics and quantum field theory. This case is made by comparing the Bohmian theory to collapse theories such as the GRW matter density and the GRW flash theory. It is argued that the Bohmian theory makes the minimal changes, (...) concerning only the dynamics and neither the ontology nor the account of probabilities, that are necessary to get from classical mechanics to quantum physics. There is no cogent reason to go beyond these minimal changes. (shrink)

The morally offensive idea of holy and total war, presented by the Deuteronomic authors as a religious duty, perplexes and disturbs us by its cruelty. We can identify in the biblical texts two different accounts of Israel's conquest of Canaan and can examine the development and interplay of these narratives - and their correlative divergent sets of moral laws. Study of these documents suggests that the notion of holy war was a retrospective invention of the last years of the monarchy. (...) It is closely connected to the Deuteronomic conception of a covenantalkinship community, and it ought to worry political theorists and theologians who find such a community attractive. (shrink)

This book traces the linguistic turns in the history of modern philosophy and the development of the philosophy of language from Locke to Wittgenstein. It examines the contributions of canonical figures such as Leibniz, Mill, Frege, Russell, Wittgenstein, Austin, Quine, and Davidson, as well as those of Condillac, Humboldt, Chomsky, and Derrida. Michael Losonsky argues that the philosophy of language begins with Locke's Essay Concerning Human Understanding. He shows how the history of the philosophy of language in the modern (...) period is marked by a dichotomy between formal and pragmatic perspectives on language and that modern philosophy has not been able to integrate these two aspects of human language. Language as a human activity and language as a syntactic and semantic system remain distinct and competing focal points, although the interplay between these points of view has driven the development of the philosophy of language.

The type of completeness Whitehead and Russell aimed for in their Principia Mathematica was what I call descriptive completeness. This is completeness with respect to the propositions that have been proved in traditional mathematics. The notion of completeness addressed by Gödel in his famous work of 1930 and 1931 was completeness with respect to the truths expressible in a given language. What are the relative significances of these different conceptions of completeness for traditional mathematics? What, if any, effects does incompleteness (...) of the type Gödel had in mind have for the evaluation of the Principia Mathematica project and other projects like it? (shrink)

Imagine that Bloggs is faced with a choice between giving a benefit to his child, or a slightly greater benefit to a complete stranger. The benefit is whatever the child or the stranger can buy for $100 — Bloggs has $100 to give away — and it just so happens that the stranger would buy something from which he would gain a slightly greater benefit than would Bloggs's child. Let's stipulate that Bloggs believes this to be, and let's stipulate, as (...) well, that he believes that the consequences of his actions are otherwise identical. He chooses to give the benefit to his child. What do we learn about Bloggs from his choice? We learn that Bloggs cares more about his child than he does about complete strangers. Nor is anyone likely to be surprised by this, for it just goes to show that he is much like the rest of us. He gives preferential treatment to his nearest and dearest when he acts, those with whom he has a special relationship, much as we do. (shrink)

Since Horn (1972) the notion of conversational implicature proposed by Grice has been put to use to explain certain interpretive differences between expressions in natural language and their counterparts in formal logic. For example, the sentences in (1) seem to convey more than they would be expected to if the natural language disjunction or had the same meaning as the logical disjunction ∨, or if the quantificational determiner some was interpreted as the existential quantifier ∃.

Translated from the original German Lenin Neuentdecken and available in English for the first time, this volume rediscovers Lenin as a strategic socialist thinker through close examination of his collected works and correspondence. Brie opens with an analysis of Lenin's theoretical development between 1914 and 1917, in preparation for his critical decision to dissolve the Constituent Assembly in January 1918 in a struggle for power. This led from the dialectics of revolutionary practice and social analysis to a new understanding of (...) socialism, which is compared and contrasted to the alternative Marxist ideas and conceptions of the state posited by Karl Kautsky and Rosa Luxemburg. Rediscovering Lenin then moves to 1921, when Lenin begins a new stage of his theoretical development concerned with resolving the reversal of the revolution’s aims and its results. This process remains unfinished, and the questions raised a hundred years ago remain: How can one intervene successfully and responsibly in social and political crises? What role do social science theories, ideological frameworks, and other practices play in transforming the economic, political and cultural power structures of a society? Brie concludes with a retrospective on the ideas developed by Marx and in the Second International, and their impact on Lenin’s strategic thinking. Placing Lenin's writing itself in the foreground and arguing from inside his own self-learning, Rediscovering Lenin focuses on the reflective relationship between ideology, theory, and practice. ​.

This essay will examine an illuminating convergence in the thoughts of Pope John Paul II and the cultural anthropologist René Girard. It will be seen that this convergence is a consequence of the shared concern of both to understand the human person in terms of its relation to other persons. So while not a personalist philosopher in the strict sense, René Girard’s concern for the interpersonal brings him close to the personalism of John Paul II, who likewise understands human subjectivity (...) in terms of the relations by which it is constituted. Both practice what might be called an “interpersonalist” personalism, which this essay will argue ought to characterize the practice of personalism in a Christian context. The essay will make this observation the basis for further reflections on the nature of personalism and its relation to the Christian intellectual tradition. (shrink)

Hume’s arguments against the cosmological argument have, in the past century, often been highly praised by commentators such as H.D.Aiken and E.C. Mossner. While Hume’s argument often receives strong philosophical support, the four major objections raised against the cosmological argument in book IX of his Dialogues hinge upon a misunderstanding of Newtonian natural philosophy. Hence, when the proper historical context is considered, Hume’s objections are weak at best, for they assume an understanding of matter and physical necessity that are inconsistent (...) with Newtonian natural philosophy. This paper will outline Hume’s objections, and explore how the formulation of the cosmological argument put forth by the English philosopher Samuel Clarke was reliant upon the best available scientific evidence, i.e. Newtonian philosophy. Consequently, any contemporary supporter of Hume who believes that his argument was successful in quenching the enlightenment era reiteration of the cosmological argument does so anachronistically.

Contemporary normative theory is understandably reluctant to consider how a hegemonic power ought to conduct itself. After all, a truly just international order, characterised by principles of freedom and equality among nations, would not include one polity so able to dominate others. The natural impulse of normative theorists then is to seek to eliminate such an imbalance. Yet, a sober assessment of political reality provides little prospect for such aspirations. The more modest alternative is to examine how hegemonic power might (...) be wielded responsibly. For most of the history of Western political thought, the problem of just hegemony was more theoretical than real, leaving few serious philosophical precedents. Yet for Roman thinkers, of both the late Republic and the early Empire, the issue presented a real and urgent problem. In this article I explore some of the attempts of Roman philosophers and historians to grapple with the unique position of the Roman state. In many cases, their theories depend in some way on Rome’s alleged special moral or constitutional qualities – and yet, they often recognised that the realities of Rome’s use of power undermined those claims to exceptionalism. I examine the Romans’ responses to this problem as they sought to think through the moral dilemmas of their situation. In classical Roman thought, we might find an interlocutor for our own attempt to think through the ethics of superpower. (shrink)
