In the Transcendental Aesthetic (TA), Kant is typically held to make negative assertations about “things in themselves,” namely that they are not spatial or temporal. These negative assertions stand behind the “neglected alternative” problem for Kant’s transcendental idealism. According to this problem, Kant may be entitled to assert that spatio-temporality is a subjective element of our cognition, but he cannot rule out that it may also be a feature of the objective world. In this paper, I show in a new (...) way how Kant’s view (focusing on his conclusions about space) is not subject to this objection, by showing that he does not make the denial about mind-independent reality that he is typically held to make. The argument develops consequences of a new reading of Kant’s expression “an sich selbst” (‘in itself’; ‘in themselves’). I argue that “an sich selbst” or “per se” has a special, judgment-level role, so that this expression does not form new noun-terms adjectivally. It follows that the conceptual unit of Kant’s “Conclusions” in the TA is simply “things” (Dinge), since “things in themselves” is not a nominal expression; Kant adopts the Wolffian ontological use of “thing” as the basic kind-term for any existent. The arguments that things per se are not in space are arguments that space cannot be a necessary property or relations of things as a kind. I show that this does not involve the positive claim about mind-independent reality that inspires the neglected alternative objection. (shrink)

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

In this chapter, I consider the largely overlooked influence of E. W. von Tschirnhaus' treatise on method, the Medicina mentis, on Wolff's early philosophical project (in both its conception and execution). As I argue, part of Tschirnhaus' importance for Wolff lies in the use he makes of principles gained from experience as a foundation for the scientific enterprise in the context of his broader philosophical rationalism. I will show that this lesson from Tschirnhaus runs through Wolff's earliest (...) philosophical discussions, and indeed continues to inform his major texts in logic and mathematics just before the publication of the German Metaphysics. In the end, my discussion has the effect of revealing Tschirnhaus to be an exceptionally important influence on Wolff's development, perhaps even as important (or so I suggest) as Leibniz. (shrink)

In attempts to come to grips with Kant’s thought, the influence of the philosophy of Christian Wolff (1679-1754) is often neglected. In this paper, I consider three topics in Kant’s philosophy of mind, broadly construed, where Wolff’s influence is particularly visible: consciousness, self-consciousness, and psychology. I argue that we can better understand Kant’s particular arguments and positions within this context, but also gain a more accurate sense of which aspects of Kant’s accounts derive from the antecedent traditions and (...) which constitute genuine philosophical innovations. (shrink)

In this paper, I consider the basis for Kant's praise of Wolff's general logic as "the best we have." I argue that Wolff's logic was highly esteemed by Kant on account of its novel analysis of the three operations of the mind (tres operationes mentis), in the course of which Wolff formulates an argument for the priority of the understanding's activity of judging.

What is the proper relation between the scientific worldview and other parts or aspects of human knowledge and experience? Can any science aim at "complete coverage" of the world, and if it does, will it undermine--in principle or by tendency--other attempts to describe or understand the world? Should morality, theology and other areas resist or be protected from scientific treatment? Questions of this sort have been of pressing philosophical concern since antiquity. The Proper Ambition of Science presents ten particular case (...) studies written by prominent philosophers, looking at how this problem has been approached from the ancient world right up to the present day.

Wolff suggests by way of the following argument that democracy appears to be irrational. Here is the argument given: 1) Ruling is a skill. 2) It is rational to leave the exercise of skills to experts [sic] 3) In a democracy the people rule. 4) The people are not experts. Therefore: 5) Democracy is irrational.

These three robust volumes make available in its entirety a collection of correspondence, held at the University of Leipzig library and comprising nearly five hundred letters, between Christian Wolff and Ernst Christoph, Graf von Manteuffel. At the time of the correspondence, Wolff was the most famous philosopher of the German Enlightenment, having taken a position in Marburg after his exile from Prussia in 1723. Manteuffel was a Saxon diplomat, advocate for the Wolffian philosophy at the Prussian court, and (...) a cofounder of the Societas Alethophilorum, a group of thinkers devoted to propagating and defending the Leibnizian-Wolffian philosophy. The decade covered by the correspondence would... (shrink)

In this paper, I consider Baumgarten’s views on the soul in the context of the Pietist critique of Wolff’s rational psychology. My primary aim is to account for the largely unacknowledged differences between Wolff’s and Baumgarten’s rational psychology, though I also hope to show that, in some cases, the Pietists were rather more perceptive in their reading of Wolff than they are typically given credit for as their criticisms frequently succeed in drawing attention to significant omissions in (...) Wolff’s discussion. (shrink)

These two volumes contain all of my articles published between 1956 and 1975 which might be of interest to readers in the English-speaking world. The first three essays in Vol. 1 deal with historical themes. In each case I as far as possible, meets con have attempted a rational reconstruction which, temporary standards of exactness. In The Problem of Universals Then and Now some ideas of W.V. Quine and N. Goodman are used to create a modern sketch of the history (...) of the debate on universals beginning with Plato and ending with Hao Wang's System L. The second article concerns Kant's Philosophy of Science. By analyzing his position vis-a-vis I. Newton, Christian Wolff, and D. Hume, it is shown that for Kant the very notion of empirical knowledge was beset with a funda mental logical difficulty. In his metaphysics of experience Kant offered a solution differing from all prior as well as subsequent attempts aimed at the problem of establishing a scientific theory. The last of the three historical papers utilizes some concepts of modern logic to give a precise account of Wittgenstein's so-called Picture Theory of Meaning. E. Stenius' interpretation of this theory is taken as an intuitive starting point while an intensional variant of Tarski's concept of a relational system furnishes a technical instrument. The concepts of inodel world and of logical space, together with those of homomorphism and isomorphism be tween model worlds and between logical spaces, form the conceptual basis of the reconstruction.

: Mendelssohn’s Philosophische Gespräche, first published in 1755, represents his first philosophical work in German and rather surprisingly for a debut, in the first two dialogues of that work Mendelssohn attempts nothing less than a defense of the legacy of the most controversial philosopher of his day, Benedict de Spinoza. In this paper, I attempt to enlarge the context, and if possible to raise the stakes, of Mendelssohn’s discussion in order to bring out what I take to be a much (...) more ambitious project on Mendelssohn’s part, namely, not only the rehabilitation of a fellow Jewish thinker but also the rehabilitation of metaphysics as such by means of a thorough accounting of the Spinozan elements in the Wolffian philosophy. As I will show, framing the project of the Gespräche too narrowly is responsible for obscuring much of what I take to be most original and insightful in Mendelssohn’s use and interpretation of Wolff’s thought, as well as his ultimate purpose in resolving what he regarded as an ongoing crisis in metaphysics that is responsible to no small extent for its widespread neglect.

In this paper, I attempt to trace the broader contours of a putative Leibnizian psychology by adopting the rather unusual, and perhaps historically dubious, strategy of outlining the continuities between Leibniz’s discussion of the soul and the much more detailed and systematic psychological writings of his German successor, Christian Wolff.

Early Modern German Philosophy (1690-1750) makes some of the key texts of early German thought available in English, in most cases for the first time. The translations range from texts by the most important figures of the period, including Christian Thomasius, Christian Wolff, Christian August Crusius, and Georg Friedrich Meier, as well as texts by consequential but less familiar thinkers such as Dorothea Christiane Erxleben, Theodor Ludwig Lau, Friedrich Wilhelm Stosch, and Joachim Lange. The topics covered range across a (...) number of areas of theoretical philosophy, including metaphysics (the immortality of the soul, materialism and its refutation, the pre-established harmony), epistemology (the principle of sufficient reason, the limits of reason with respect to matters of faith), and logic (the role of prejudices in cognition and the doctrine of truth).

In this paper, I claim that Kant’s subjective deduction in the first edition of the KrV is to be understood in terms of an investigation of the fundamental force(s) (Grundkraft) of the soul, an investigation essential to Wolffian psychology and much debated throughout Germany in the second half of the 1700’s. I argue that the subjective deduction is indeed presented by means of the exposition of the three-fold syntheses but only insofar as these syntheses are employed as pointers towards each (...) of three original sources of cognition. Only taken as such can we do justice not only to the argument’s unique concern as distinct from that of the objective deduction, but also to its dependence upon the justificatory results of that deduction which was after all Kant’s “primary concern”.

The thesis of this book is that Herbert Marcuse is "indispensable to the theory and practice of the New Left." The one-dimensional quality of contemporary everyday life is to be disrupted by a critical theory of society based upon the works of Karl Marx as interpreted and brought to bear upon the 20th Century. Hence, this collection of six New Left studies on Herbert Marcuse is called Critical Interruptions. The contributors are former students of Marcuse and all are younger than (...) thirty-five. The work is dedicated to Theodor W. Adorno and Ho Chi-Minh. The book is poorly edited; not only does the heavy Marcusean terminology make intelligibility slow; but poor rhetoric, grammar and punctuation also add to the slowness of the pace. The content of the essays, however, is uniformly very worthwhile and the book deserves a careful reading. The Marcuse Festschrift of 1967, edited by Kurt H. Wolff and Barrington Moore, Jr., entitled The Critical Spirit, was a collection of essays "in honor of Herbert Marcuse." This 1970 book, Critical Interruptions, is addressed to the exposition, up-dating and critique of Marcuse himself. Therefore, this present work is of immediate help to all readers and students of Marcuse. Paul Breines, the editor, wrote the first essay, "From Guru to Spectre: Marcuse and the Implosion of the Movement"; this is a history of Marcuse's relation to the New Left over the past few years. The second essay, "Individuation as Praxis," by Shierry M. Weber, is an incisive and insightful critique of the New Left while studying the meaning of praxis, the personal dimensions of individuality and exploring realistic alternatives for a viable counter culture. "Reversals and Lost Meanings" by Russell Jacoby is a short attempt at dialectics. William Leiss' study, "The Critical Theory of Society: Present Situation and Future Tasks," is a fine review of the major representatives of the Frankfurt School of social philosophers. "On Sexuality and Politics in the Work of Herbert Marcuse" by John David Ober, explains the continuity and development in Marcuse's thought on sexuality from Eros and Civilization through One-Dimensional Man. Finally, the last essay, "One-Dimensionality: The Universal Semiotic of Technological Experience" by Jeremy J. Shapiro is an extended commentary on Marcuse's most recent thought as applied to the advancing technology of the age. The editor openly disclaims any inner unity to the six essays. The studies, however, reveal that at least these six students of Marcuse from the New Left understand the Master very well and are able to extend his thought successfully to key contemporary issues. At the end, there is a greater unity to the book than the editor anticipated.--E. W. R. (shrink)

Meier’s Gedancken von dem Zustande der Seele nach dem Tode (Gedancken) deserves a prominent place among treatments of the immortality of the soul in 18th century German philosophy, both within and without the Wolffian tradition of rational psychology. It does not wilt next to Mendelssohn’s Phädon in its quality of expression, and might even be compared with Kant’s discussion in the Paralogisms chapter of his Kritik der reinen Vernunft in terms of the boldness of its argument and its philosophical rigour. (...) The Gedancken contributed greatly to Meier’s growing reputation as an original thinker and helped him emerge from the shadow of his famous colleague in the philosophy faculty at the Friedrichs-Universität in Halle, Christian Wolff; moreover, it provoked detailed responses on the part of its critics and even made Meier himself the subject of official investigation as an accused aider and abettor of freethinkers. Meier’s Gedancken thus stands as a work of central importance within his own philosophical corpus and in the history of 18th century German rational psychology more generally. Accordingly, in this Introductory Essay, I will present the context and argument, as well as the reception, of the Gedancken, and then consider Meier’s subsequent defense of his controversial text.

This paper considers how Descartes's and Hume's sceptical challenges were appropriated by Christian Wolff and Johann Nicolaus Tetens specifically in the context of projects related to Kant's in the transcendental deduction. Wolff introduces Descartes's dream hypothesis as an obstacle to his account of the truth of propositions, or logical truth, which he identifies with the 'possibility' of empirical concepts. Tetens explicitly takes Hume's account of our idea of causality to be a challenge to the `reality' of transcendent concepts (...) in general, a challenge he addresses by locating the source of this concept in the understanding rather than in the imagination. After considering this background, I turn to Kant's deployment of apparently traditional sceptical concerns at the outset of the transcendental deduction and argue that he does not there intend to introduce a global sceptical challenge and, accordingly, that there are historical grounds for doubting that the transcendental deduction is intended as an anti-sceptical argument.

Wolff sees Leibniz, in contrast with, for example, the epistemologist Berkeley, as "in erster Linie Lebensphilosoph", and thus a forerunner of Nietzsche. The historical influence, mediated by Schopenhauer and Hartmann, was recognized by Nietzsche only near the end of his career. New Essays IV.vi.7 ad fin., which speaks of "the pleasure of being deceived by an agreeable perspective," is interpreted thus : "Leibniz spricht hier wie Nietzsche:... Aufheben der Illusion... würde den Menschen zum Wahnsinn treiben."--R. W.

According to Wolff, Rawls’ thinking developed through three stages, represented respectively by his article "Justice as Fairness," which appeared in 1958; a second article, "Distributive Justice," published nine years later; and the 1971 book A Theory of Justice. Wolff proceeds, in his "reconstruction and critique," by setting forth his understanding of "the central idea, or key, of Rawls’ work", then tracing the development of the idea from Rawls’ article of 1958 through the "final baroque complexity" of the 1971 (...) book, continuing with a comparison of Rawls and Kant, and in the end highlighting important substantive flaws in Rawls’ project.

I consider Kant's criticism of rational psychology in the Paralogisms of Pure Reason in light of his German predecessors. I first present Wolff's foundational account of metaphysical psychology with the result that Wolff's rational psychology is not comfortably characterized as a naïvely rationalist psychology. I then turn to the reception of Wolff's account among later German metaphysicians, and show that the same claim of a dependence of rational upon empirical psychology is found in the publications and lectures (...) of Kant's pre-Critical period. Considering the Paralogisms in this context reveals Kant's conception of rational psychology to be distinctly novel and has important consequences in shifting the argumentative focus of the chapter. (shrink)

In this paper, I challenge the assumption that Kant’s Third Paralogism has to do, first and foremost, with the question of personal identity.

In what follows, I will detail Kant's criticism of the Leibnizian conception of mind as it is presented in key chapters of the Kritik der reinen Vernunft . Approaching Kant with such a focus goes against the current predominant in contemporary Kant scholarship. Kant's engagement with Leibniz in the KrV is often taken as limited to the refutation of the latter's relational theory of space and time in the Aesthetic and the general criticism presented in the Amphiboly chapter, inasmuch as (...) Kant is taken to be primarily concerned with addressing empiricist opponents (a focus particularly evident in the English-language commentary). In addition, the argument against rational psychology in the Paralogisms is taken as challenging an essentially Cartesian position. The first two chapters of this project will introduce the Leibnizian conception of the mind, contrasting it with its Cartesian predecessor, and consider the career of the Leibnizian conception in the schools of 18th century Germany. As I will show, it was the Leibnizian conception of mind that held sway, despite scattered challenges, and that would have primarily been on Kant's mind when he turned to consider the extravagant claims of metaphysical psychology. In chapters 3-5, I turn to Kant's criticism of this conception as presented in the Transcendental Analytic of the KrV . There, I show how the subjective and objective deductions, in addition to the Amphiboly chapter, all address the Leibnizian claim of a parallelism between the investigations of the mental and the physical. In chapters 6-8, I consider the case against the Leibnizian conception of mind as presented in the Transcendental Dialectic, claiming that the doctrine of transcendental illusion plays an important (though largely ignored) role in explaining the grounds of the Leibnizian conception as it is transmitted in the rational psychology of Wolff, Baumgarten, Crusius, and Kant himself in the 1770's. Moreover, I argue that the limits Kant sets to empirical psychology are consistent with his criticism of the Leibnizian conception of mind, and, significantly, are motivated by deeper practical concerns.
