Seventeenth-century optics naturalizes the eye while estranging the mind from objects. A mere screen, on which rests a blurry array of light stains, the eye no longer furnishes the observer with genuine re-presentations of visible objects. The intellect is thus compelled to decipher flat images of no inherent epistemic value, accidental effects of a purely causal process, as vague, reversed reflections of wholly independent objects. Reflecting on and trespassing the boundaries between natural and artificial, orderly and disorderly, this optical paradox (...) is a Baroque phenomenon; and it is the origin of Descartes’ celebrated doubt---whether we know anything at all.

The following paper, together with its sequel ("The use and non-use of mathematics"), is a study in the mathematization of nature. It looks into the history of one of the most emblematic achievements of this fundamental aspect of the making of modem science - the Inverse Square Law of universal gravitation - before its celebrated application by Newton to celestial mechanics. What did it take, we ask, to tum a particular mathematical ratio into a candidate for a law of nature?

The mathematical nature of modern science is an outcome of a contingent historical process, whose most critical stages occurred in the seventeenth century. ‘The mathematization of nature’ (Koyré 1957 , From the closed world to the infinite universe , 5) is commonly hailed as the great achievement of the ‘scientific revolution’, but for the agents affecting this development it was not a clear insight into the structure of the universe or into the proper way of studying it. Rather, it was (...) a deliberate project of great intellectual promise, but fraught with excruciating technical challenges and unsettling epistemological conundrums. These required a radical change in the relations between mathematics, order and physical phenomena and the development of new practices of tracing and analyzing motion. This essay presents a series of discrete moments in this process. For mediaeval and Renaissance philosophers, mathematicians and painters, physical motion was the paradigm of change, hence of disorder, and ipso facto available to mathematical analysis only as idealized abstraction. Kepler and Galileo boldly reverted the traditional presumptions: for them, mathematical harmonies were embedded in creation; motion was the carrier of order; and the objects of mathematics were mathematical curves drawn by nature itself. Mathematics could thus be assigned an explanatory role in natural philosophy, capturing a new metaphysical entity: pure motion. Successive generations of natural philosophers from Descartes to Huygens and Hooke gradually relegated the need to legitimize the application of mathematics to natural phenomena and the blurring of natural and artificial this application relied on. Newton finally erased the distinction between nature’s and artificial mathematics altogether, equating all of geometry with mechanical practice. (shrink)

The following is the second part of our Archaeology of the Inverse Square Law. Together these papers examine the transformation of the inverse square ratio from its origins in a metaphysical image of medieval thought in Grosseteste and the perspectivist tradition, through a playful magical practice in the Renaissance with Cusanus and Dee, and into a mathematical tool, applicable to the physical world. This last transformation allowed Newton to condense the geometrical image into a celebrated algebraic equation for universal gravity, (...) but it proved particularly confusing for the people who wrought it, Kepler and Hooke.

This paper presents the Rational Action, Noisy Choice for Habituation (RANCH) model. The model was evaluated with adult looking time collected from a paradigm analogous to the infant habituation paradigm. And the model captured key patterns of looking time documented in developmental research: habituation and dishabituation.

Difficulties understanding speech form one of the most prevalent complaints among older adults. Successful speech perception depends on top-down linguistic and cognitive processes that interact with the bottom-up sensory processing of the incoming acoustic information. The relative roles of these processes in age-related difficulties in speech perception, especially when listening conditions are not ideal, are still unclear. In the current study, we asked whether older adults with a larger working memory capacity process speech more efficiently than peers with lower capacity (...) when speech is presented in noise, with another task performed in tandem. Using the Eye-tracking of Word Identification in Noise Under Memory Increased Load an adapted version of the “visual world” paradigm, 36 older listeners were asked to follow spoken instructions presented in background noise, while retaining digits for later recall under low or high memory load. In critical trials, instructions directed listeners’ gaze to pictures of objects whose names shared onset or offset sounds with the name of a competitor that was displayed on the screen at the same time. We compared listeners with different memory capacities on the time course for spoken word recognition under the two memory loads by testing eye-fixations on a named object, relative to fixations on an object whose name shared phonology with the named object. Results indicated two trends. For older adults with lower working memory capacity, increased memory load did not affect online speech processing, however, it impaired offline word recognition accuracy. The reverse pattern was observed for older adults with higher working memory capacity: increased task difficulty significantly decreases online speech processing efficiency but had no effect on offline word recognition accuracy. Results suggest that in older adults, adaptation to adverse listening conditions is at least partially supported by cognitive reserve. Therefore, additional cognitive capacity may lead to greater resilience of older listeners to adverse listening conditions. The differential effects documented by eye movements and accuracy highlight the importance of using both online and offline measures of speech processing to explore age-related changes in speech perception.

The following describes the concept of apoliticism, distinguishing it from indifference, which is also considered a negative attitude toward politics. Whereas apoliticism is the rejection of the official political institutions, possibly with the plan of an alternative system, the indifferent rejects politics altogether and is politically disinterested. If reflective negativism rejects politics as mechanism, the indifferent rejects it as a pursuit. I also distinguish between the extra-political, as the condition of being outside of any environment in which free deliberation and (...) public engagement is possible, and the supra-political condition, as blurring the line between public political activities and rites prescribed by the state on the one hand and the private sphere of the individual on the other hand. If different, both are forms of political poverty. These concepts may serve as means for a more nuanced understanding of the structure of apolitical attitudes. (shrink)

En el presente estudio analizaremos la expresión del conflicto en el lenguaje, donde la lucha palabra-letra impregna la teoría agónica del lenguaje y marca la trascendencia sobre la relación historia-intrahistoria. Asimismo, presentaremos la dimensión creadora del lenguaje, relevante desde el Unamuno contemplativo, y el papel desempeñado por el diálo go a la hora de expresar los dos poíos del conflicto, agónico y contem plativo.

An important aspect of the debate between the A-theory and the B-theory of time relates to the supposed implications of each for some of the most basic human attitudes and stances. The asymmetry in our attitudes towards past and future events in our life (pleasant and unpleasant), and towards the temporal limits of our existence, that is, toward birth and death, is supposedly considered differently by the two theories. I argue that our attitudes are neither justified nor discredited by anything (...) which is in debate between the A-Theory and the B-theory, and therefore that neither theory of time is supported by the asymmetry in our attitudes.

The paper develops a conception of marital love as a complex recognitive relation, which I articulate by juxtaposing it against other recognitive relations that figure in Hegel's theory of modern civil society (i.e., respect and esteem). Drawing on Hegel's early writings, I argue that, if love is to provide its unique sort of recognition, it must obtain between “living beings who are equal in power”—a peculiar form of equality that I name (drawing on Stanley Cavell's work) “dynamic equality.” I conclude (...) that it is by Hegel's own lights that we should reject his notorious conception of the sexual difference. However, I also offer reasons why, from Hegel's early 19th century perspective, he could consider the following two conditions as compatible: (1) equality within marriage and (2) sexual hierarchy outside marriage, namely, in civil society.

In the Ethics,1 Spinoza presents a rigorous naturalistic view of man and nature. Man is a part of nature, a subject of the same domain—not a domain separate from it, nor a domain within that of nature. Man cannot act against nature or in an unnatural way; in comparison with any other part or creature of nature, man is not special, more important or qualitatively different. All general laws of nature apply equally to animals, inanimate objects, humans, God, the mind, (...) and the affects. Nature can be explicated based on necessary causes, and there are no extra-natural factors that affect it or anything in it: no supernatural power or metaphysical principles create or regulate it, and no separate methods of explanation ..

Cognitive scientists distinguish between automatic and controlled mental processes. Automatic processes are either innately involuntary or become automatized through extensive practice. For example, reading words is a purportedly automatic process for proficient readers and the Stroop effect is consequently considered the “gold standard” of automated performance. Although the question of whether it is possible to regain control over an automatic process is mostly unasked, we provide compelling data showing that posthypnotic suggestion reduced and even removed Stroop interference in highly hypnotizable (...) individuals. Drawing on a large sample of highly hypnotizable participants, we examined the effects of suggestion on Stroop performance both with and without a posthypnotic suggestion to perceive the input stream as meaningless symbols. We show that suggestion administered to highly hypnotizable persons significantly reduced Stroop interference and derailed a seemingly automatic process. (shrink)

Practical Reason and Norms focuses on three problems: In what way are rules normative, and how do they differ from ordinary reasons? What makes normative systems systematic? What distinguishes legal systems, and in what consists their normativity? All three questions are answered by taking reasons as the basic normative concept, and showing the distinctive role reasons have in every case, thus paving the way to a unified account of normativity. Rules are a structure of reasons to perform the required act (...) and an exclusionary reason not to follow some competing reasons. Exclusionary reasons are explained, and used to unlock the secrets of orders, promises, and decisions as well as rules. Games are used to exemplify normative systems. Inevitably, the analysis extends to some aspects of normative discourse, which is truth-apt, but with a diminished assertoric force. (shrink)

What does it mean to assert or deny the existence of a legal system? How can one determine whether a given law belongs to a certain legal system? What kind of structure do these systems have, that is--what necessary relations obtain between their laws? The examination of these problems in this volume leads to a new approach to traditional jurisprudential question, though the conclusions are based on a critical appraisal, particularly those of Bentham, Austin, Kelsen, and Hart.

In this paper I defend the rejection of fatalism about the past by showing that there are possible circumstances in which it would be rational to attempt to bring about by our decisions and actions a necessary and sufficient condition, other things being equal, for something which we see as favorable to have occurred in the past. The examples I put forward are analogous to our attempts to bring about the occurrence of future events, and demonstrate the symmetry between the (...) past and the future in this respect. (shrink)

A partir de l'idée de “ folie ” chez S. Paul , Fr. Le Gal explore le thème de “ la folie sainte de Dieu ” qui n'est autre que la révélation de son amour fou pour l'homme. Examinant tout d'abord la polysémie du terme, sa réflexion porte en première partie sur Jésus-Christ comme “ homme de la dérision et Dieu à la folie ”, examinant au passage la parabole comme lieu de l' “ ironie christique ”. Dans la seconde (...) partie, c'est Paul qui révèle le contenu à la fois christologique, théologique et spirituel de la folie dans la tension entre la scandale de la croix et le risque pour l'apôtre et le croyant de n'être pas reçus. C'est pourtant là que se manifestera la “ folie sainte ”.Beginning with the idea of 'folly " in St. Paul , Fr Le Gal explores the theme of "the holy folly of God " that is nothing other than the revelation of his mad love for man. Examining first of all the polysemy of the term, his reflection in the first part is on Jesus Christ as "man of derision and God of folly ", examining in passing the parable as the area of "christic irony ". In the second part, it is Paul who reveals, at the same time, the christological, theological, and spiritual content of folly in the tension between the scandal of the cross and the risk for the apostle and the believer not to be accepted. It is there, nevertheless, that the "holy folly " manifests itself. (shrink)

This book describes a novel conception of reality, one that uniquely incorporates an idealistic view of existence with an account of objectivity. It introduces a general model of conceptual analysis and demonstrates its effectiveness in exposing and establishing the existence of conceptual ties. The book begins by introducing the tools and principles needed for the conceptual analysis undertaken in chapters that follow. Next, it presents a detailed examination into existence, contingency, idealism, self-consciousness and natural laws. In the process, the author (...) critically examines the conceptions of existence held by Kant, Frege and Russell; argues that the determinations of past, present and future are subjective in the sense that they imply the existence of consciousness in relation to which they are fixed; shows that every possible reality includes sufficient conditions for self-consciousness; and confronts the question of the "uniformity of nature," which states that reality is subject to natural laws. In the end, the idealistic conception of reality developed in this book implies that existence is relative, rather than absolute, in the sense that it is determined in relation to a point of view internal to reality. This view of existence implies that reality necessarily exists. (shrink)

What are our duties or rights? How should we act? What are we responsible for? Joseph Raz examines the philosophical issues underlying these everyday questions. He explores the nature of normativity--the reasoning behind certain beliefs and emotions about how we should behave--and offers a novel account of responsibility.

In this paper I attempt to refute the instrumental conception of practical reason, and thus defend a rationalist conception of practical reason. I argue that, far from merely playing an instrumental role, reason can be used by an agent to evaluate, that is, to approve or reject, final ends, which might be suggested by desires, and further to determine final ends independently of any desires, whether actual or potential, that the agent might have. My argument relies on an analysis of (...) the concept of intention, and, more specifically, on the distinction between want and intention. I argue that the notion of an intentional action entails that reason can be used to evaluate and determine final ends. (shrink)

In this paper I argue that a period of time during which nothing changes in the world is impossible. I do this by exposing the conceptual dependence of time on change. My argument rests on a view of necessary conditions for the meaningfulness of expressions in language. I end up concluding that the meaningfulness of temporal expressions assumes change.

ABSTRACT According to the Symmetry Argument against the fear of death, our attitudes towards birth and death should be identical. In this paper I defend the Deprivation Account of the badness of death, according to which death is bad because it deprives one of future goods. After rejecting previous attempts to explain and justify the asymmetry in our attitudes towards birth and death I argue that the asymmetry in our attitudes is both explained and justified by the fact that contrary (...) to birth, death is not viewed as a nomologically necessary condition for life, and therefore death is viewed as an unnecessary limitation of life.

In this chapter I analyze the concept of self-consciousness in order to uncover its conceptual structure. The conclusions of this analysis describe some of the necessary categories of conscious experience. The concept of the self, the concept of consciousness, the concept of objectivity, the temporal distinctions between past, present, and future, and finally the idea of natural regularities, are found to be necessary categories for conscious experience, and hence describe the fundamental cognitive structure of self-conscious beings.

The principle of the "uniformity of nature" states that reality is subject to natural laws. In this paper I argue that a weak version of the principle of the uniformity of nature is a necessary truth. According to this weakened principle, every reality for which the question of its subjection to natural laws can arise is subject to natural laws. I argue that this question arises only for a subject who knows of the existence of objective reality, qua objective (that (...) is, reality which is independent of any knowledge of it). I show that a necessary condition for knowledge of objective reality, qua objective, is that the subject can acquire knowledge of past and future events, which he does not perceive directly through his senses, and that only natural (contingent) regularities enable the subject to do so. Hence, I conclude that every reality for which the question of its subjection to natural laws can arise is subject to natural laws. (shrink)

Formulated as a common conceptual ground for all democracies, Popper's notion of the open society sprang from the mid-20th century context that demonstrated democracy's vulnerability to hijacking through its own electoral mechanisms. Popper's concept may accordingly be considered as a resource for combatting the populist appeal to majority decision and its threat of diminishing individual and minority rights. I examine the affirmative and critical aspects of such a consideration. On the affirmative side, the open-society concept allows room for both majority (...) decision and the rights of individuals and minorities, as well as for particular group identities and class demands, showing that they may all cooperate to facilitate the growth of liberty, knowledge and the quality of life. Democratic institutions are justified from the grounds of this concept. Populism's equation of democracy with majority decision is, thus, incompatible with democracy's essence: decision by majority exists to cater to the vision that justifies that mode of decision making itself and cannot stay legitimate if it scuttles that vision. The more critical interpretation focuses on a detail of the open society's projected development. Popper tasks democracy's institutions with assuring conditions for progress through the expansion of knowledge. Popper expects the same process to modify the civic sphere's scope and content, as political bodies will be increasingly exposed to the expanding insights of scholarship and science. This anticipation involves grading the agents engaged in these two respective spheres, as well as looking forward to the ascendancy of one of them. Accordingly, the open-society concept might validate claims that, when seeking to confine the scope of majority decision through an emphasis on rights and law, constitutionalist and liberal approaches to democracy are subtly elitist.
