The pantheist ontology of Baruch Spinoza (b.1632 – d.1677) is an attempt to deny the accountability of political evil. -/- Spinoza’s instinct for statist control and his distrust of the common man are displayed in Theological-Political Treatise (published 1670). His masterwork, Ethics (published posthumously in 1677), is a bold attempt (in the guise of ontology) to classify minds and bodies as attributes of the State. -/- In Ethics, Spinoza ‘outlaws’ any vantage point from which we can address or protest the (...) kind of ‘perfect power’ -- and its attendant evils -- that constitute the essence and existence of the State.

Newman’s zips act as a kind of intervention or temporal event that differentiates the canvas, preventing Being from falling into the anonymous and impersonal il y a. The zip is what might be described as ecstatic temporality (ecstatic from the Ancient Greek ek “out” + histanai “to place, cause to stand out”). Time not only gives sense or meaning to Being, it marks the emergence of sensation, the physical materiality of something or someone.

It is a popular misconception that Spinoza was a pantheist or even an atheist. He was not. Like the medieval Kabbalists, Spinoza was a panentheist.

Hermann Cohen agreed with Immanuel Kant that ethics must be directed towards the well-being of humanity. The essential feature of this is its universality. As Cohen saw it, progress was (or at least ought to be) moving towards universal suffrage and democratic socialism. Following Kant, Cohen defended the so-called categorical imperative; that we should treat humanity in other persons always as an end and never as a means only. (Kant’s famous definition of the categorical imperative is to “act only according (...) to that maxim whereby you can, at the same time, will that it should become a universal law.”). (shrink)

The purpose of this essay is to make the case for a heterodox reading of Leibniz’s The Monadology (published 1720) through the lens of Professor John Wheeler’s hypothesis of the one-electron universe (proposed in 1940). My conjecture is this: That there exists in the knowable universe only one monad; that this monad traverses time in both directions, eventually criss-crossing the entire past and future history of the universe; and that this singular monad interacts with itself countless times, thereby filling the (...) universe with simultaneous appearances of itself. In the course of this article I will consider the possibility that our solitary monad is synonymous with Leibniz’s God, or if the monad in question is rather a created substance that is alone with God, a notion that gains some traction thanks to Leibniz’s admiration for the solipsism of Saint Teresa of Avila. I will also consider whether the one-monad hypothesis is consistent with Leibniz’s own views on harmony, simplicity and perfection. (shrink)

In 1936, Jewish-Russian philosopher Lev Shestov was invited by the Histadrut to give a series of lectures in Eretz Israel. He was warmly received by audiences in Jerusalem, Haifa and Tel Aviv. But Shestov and his writings are now largely forgotten. Here is his story.

Hermann Cohen made a distinction between the logic of science and the ideal of ethics, and noted that the natural world and the world of ethics are perceived very differently. This is because the order of the physical world is unchangeable (e.g, the sun sets in the west, night follows day, etc), while in the ideal world ethical rules can be accepted or rejected. It seems there should be one explanation for science, which is empirically self-evident, and another for ethics, (...) which is something that is open to debate. Cohen reasoned there must be something that allows science and ethics to coexist and interrelate. (shrink)

Anticipating Martin Buber, Hermann Cohen said we must recognize the living, breathing individual as a “Thou,” and not just as a generic example of humanity. As significant as the universal ethical ideal is for Cohen, he recognized that ethics is concerned with individuals only insofar as they are members of humanity as a whole. Ethics can’t always deal with individual moral feelings or with sin. In other words, it is religion -- rather than ethics -- that concerns itself with the (...) sin of the individual. (shrink)

There is only one and unique substance in existence, a substance that is infinite, self-caused, and eternal. This substance is the spatio-temporal world. But it is also God, says Baruch Spinoza, the Sephardi Jew from Amsterdam excommunicated by the Talmud Torah congregation.

"Misbegotten Muses" is an analysis of -the- historical method, an illumination of history's failure to provide insight into crucial human events. The book offers alternate methods of interpretation, and deals with a broad range of subjects, from Cotton Mather, to The Donner Party, to James Agee. From symbol, to myth, to science-and-religion.".

Behavioural evidence suggests that cephalopod molluscs may have a form of primary consciousness. First, the linkage of brain to behaviour seen in lateralization, sleep and through a developmental context is similar to that of mammals and birds. Second, cephalopods, especially octopuses, are heavily dependent on learning in response to both visual and tactile cues, and may have domain generality and form simple concepts. Third, these animals are aware of their position, both within themselves and in larger space, including having a (...) working memory of foraging areas in the recent past. Thus if using a ‘global workspace’ which evaluates memory input and focuses attention is the criterion, cephalopods appear to have primary consciousness. (shrink)

Logic has pride of place in mathematics and its 20th century offshoot, computer science. Modern symbolic logic was developed, in part, as a way to provide a formal framework for mathematics: Frege, Peano, Whitehead and Russell, as well as Hilbert developed systems of logic to formalize mathematics. These systems were meant to serve either as themselves foundational, or at least as formal analogs of mathematical reasoning amenable to mathematical study, e.g., in Hilbert’s consistency program. Similar efforts continue, but have been (...) expanded by the development of sophisticated methods to study the properties of such systems using proof and model theory. In parallel with this evolution of logical formalisms as tools for articulating mathematical theories (broadly speaking), much progress has been made in the quest for a mechanization of logical inference and the investigation of its theoretical limits, culminating recently in the development of new foundational frameworks for mathematics with sophisticated computer-assisted proof systems. In addition, logical formalisms developed by logicians in mathematical and philosophical contexts have proved immensely useful in describing theories and systems of interest to computer scientists, and to some degree, vice versa. Three examples of the influence of logic in computer science are automated reasoning, computer verification, and type systems for programming languages. (shrink)

This study reconstructs the relationship between philosophy and politics in the way in which Heidegger's failure as a politician influenced the redevelopment of philosophy in the 1930s. The author also explains how Heidegger's failure influenced the content and direction of his later work.

Studies the politics of Heidegger in terms of "thrownness" or "existential contingency". Attempts to think through Heidegger's philosophy in a manner that parallels his own dialogue with other key western thinkers.

The proof theory of many-valued systems has not been investigated to an extent comparable to the work done on axiomatizatbility of many-valued logics. Proof theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. One particular method for systematically obtaining calculi for all finite-valued logics was invented independently by several researchers, with slight variations in design and presentation. The main aim of this report is to develop the proof theory of finite-valued first order (...) logics in a general way, and to present some of the more important results in this area. In Systems covered are the resolution calculus, sequent calculus, tableaux, and natural deduction. This report is actually a template, from which all results can be specialized to particular logics.

Having visited Ireland regularly during the 1930s, Ludwig Wittgenstein resigned his Cambridge philosophy professorship in 1947 and moved there, living in a fishing village on the Atlantic coast and hotels in Dublin and the Wicklow Mountains. Although Wittgenstein spent some time out of the country, Ireland was effectively his base for three very productive years during which he worked on what would become one of his key books, the posthumously published Philosophical Investigations. Wittgenstein in Ireland represents the first sustained account (...) of Wittgenstein's time in Ireland, placing it in its historical context. Wall pays a good deal of attention to the representation of the Irish landscape in which the Austrian philosopher found himself able to work; a large part of his writings were produced in the bleak landscapes of Ireland and Norway.

Despite their differences in origin, the three influential schools of twentieth-century continental cultural criticism--the Frankfurt School, existentialism, and poststructuralism--have long been treated as an ensemble and with critical hesitancy. Examining these schools as responses to the apparent collapse of Western civilization in the twentieth-century and as formidable intellectual challenges to the cultural legacies of the Enlightenment, this book provides a productive base for criticism and broadens our understanding of their histories and reception.

Previous findings indicate that negative arousal enhances bottom-up attention biases favouring perceptual salient stimuli over less salient stimuli. The current study tests whether those effects were driven by emotional arousal or by negative valence by comparing how well participants could identify visually presented letters after hearing either a negative arousing, positive arousing or neutral sound. On each trial, some letters were presented in a high contrast font and some in a low contrast font, creating a set of targets that differed (...) in perceptual salience. Sounds rated as more emotionally arousing led to more identification of highly salient letters but not of less salient letters, whereas sounds’ valence ratings did not impact salience biases. Thus, arousal, rather than valence, is a key factor enhancing visual processing of perceptually salient targets. (shrink)

Methods available for the axiomatization of arbitrary finite-valued logics can be applied to obtain sound and complete intelim rules for all truth-functional connectives of classical logic including the Sheffer stroke and Peirce’s arrow. The restriction to a single conclusion in standard systems of natural deduction requires the introduction of additional rules to make the resulting systems complete; these rules are nevertheless still simple and correspond straightforwardly to the classical absurdity rule. Omitting these rules results in systems for intuitionistic versions of (...) the connectives in question. (shrink)

At the University of Sheffield during 2011 and 2012, a leading group of philosophers, psychologists, and others gathered to explore the nature and significance of implicit bias. The two volumes of Implicit Bias and Philosophy emerge from these workshops. Each volume philosophically examines core areas of psychological research on implicit bias as well as the ramifications of implicit bias for core areas of philosophy. Volume I: Metaphysics and Epistemology is comprised of two parts: “The Nature of Implicit Attitudes, Implicit Bias, (...) and Stereotype Threat,” and “Skepticism, Social Knowledge, and Rationality.” The first part contains chapters examining the relationship between implicit attitudes and “dual process” models of the mind; the role of affect in the formation and change of implicit associations; the unity (or disunity) of implicit attitudes; whether implicit biases are mental states at all; and whether performances on stereotype-relevant tasks are automatic and unconscious or intentional and strategic. The second part contains chapters examining implicit bias and skepticism; the effects of implicit bias on scientific research; the accessibility of social stereotypes in epistemic environments; the effects of implicit bias on the self-perception of members of stigmatized social groups as rational agents; the role of gender stereotypes in philosophy; and the role of heuristics in biased reasoning.
