This entirely new translation of Critique of Pure Reason by Paul Guyer and Allan Wood is the most accurate and informative English translation ever produced of this epochal philosophical text. Though its simple, direct style will make it suitable for all new readers of Kant, the translation displays a philosophical and textual sophistication that will enlighten Kant scholars as well. This translation recreates as far as possible a text with the same interpretative nuances and richness as the original.

Describes the various senses as sensory systems that are attuned to the environment. Develops the notion of rich sensory information that specifies the distal environment. Includes a discussion of affordances.

In this exceptional work Berkeley makes the striking claim that physical things consist of nothing but ideas and therefore do not exist outside the mind. This claim establishes him as the founder of the idealist tradition in philosophy. The text printed in this volume is the 1734 edition ofthe Principles, which represents Berkeley's mature thought. Also included are four important letters between George Berkeley and Samuel Johnson, written between 1729 and 1730, an analysis of the Principles, and a glossary.

Though my title speaks of Kant’s mathematical realism, I want in this essay to explore Kant’s relation to a famous mathematical anti-realist. Specifically, I want to discuss Kant’s influence on L. E. J. Brouwer, the 20th-century Dutch mathematician who built a contemporary philosophy of mathematics on constructivist themes which were quite explicitly Kantian. Brouwer’s theory is perhaps most notable for its belief that constructivism requires us to abandon the traditional logic of mathematical reasoning in favor of different canon of reasoning, (...) called intuitionistic logic. Brouwer thought that classical logic is intrinsically bound up with a nonconstructive view of mathematics. This means that, according to Brouwer, when we do mathematics we must give up bivalence, we must no longer use such familiar logical laws as excluded middle, and we must sometimes forebear from the classic method of reductio ad absurdum. All of these are intuitionistically invalid classical principles. (shrink)

If a tree falls in the forest and no one is present to hear it, does it make a sound? It does not, according to George Berkeley. Originally published in 1710, this landmark of Western philosophy introduced a revolutionary concept: immaterialism, which asserts that to be is to perceive or be perceived. The treatise opens with an assault on Locke's theory of abstract ideas and proceeds with arguments that sensible qualities exist only when perceived as ideas. Physical objects, he claims, (...) are no more than collections of qualities, and these sensible objects, too, are merely ideas. Berkeley relates his position to the achievements of eighteenth-century science, and proclaims the compatibility of immaterialism with traditional religion. (shrink)

First published in 1713, this work was designed as a vivid and persuasive presentation of the remarkable picture of reality that Berkeley had first presented two years earlier in his Principles of Human Knowledge. His central claim there, as here, was that physical things consist of nothing but ideas in minds--that the world is not material but mental. Berkeley uses this thesis as the ground for a new argument for the existence of God, and the dialogue form enables him to (...) raise and respond to many of the natural objections to his position. The text printed in this volume is that of the 1734 edition of the Dialogues. (shrink)

We cannot imagine two straight lines intersecting at two points even though they may do so. In this case our abilities to imagine depend upon our abilities to visualise.

Independently of any eighteenth century work on the geometry of parallels, Thomas Reid discovered the non-euclidean "geometry of visibles" in 1764. Reid's construction uses an idealized eye, incapable of making distance discriminations, to specify operationally a two dimensional visible space and a set of objects, the visibles. Reid offers sample theorems for his doubly elliptical geometry and proposes a natural model, the surface of the sphere. His construction draws on eighteenth century theory of vision for some of its technical features (...) and is motivated by Reid's desire to defend realism against Berkeley's idealist treatment of visual space.

In lieu of an abstract, here is a brief excerpt of the content:Kant's Critique of Berkeley HENRY E. ALLISON THE CLAIMTHAT KANT'S IDEALISM,or at least certain strands of it, is essentially identical to that of Berkeley has a long and distinguished history. It was first voiced by several of Kant's contemporaries such as Mendelssohn, Herder, Hamann, Pistorius and Eberhard who attacked the alleged subjectivism of the Critique of Pure Reason. 1 This viewpoint found its sharpest contemporary expression in the notorious (...) Garve-Feder review to which Kant responded at length in the Prolegomena. In subsequent times it has been championed by Schopenhauer, and most nineteenth century German commentators on the relation between the two philosophers. 2 In addition, it has been, and continues to be, the prevailing view of the vast majority of British writers on Kant, including, with significant qualifications, Norman Kemp Smith. 3 This tradition continues despite the fact that Kant specifically, and in no uncertain terms, repudiated this identification in the Prolegomena and the second edition of the Critique. In both works he responds to the charges of subjectivism, and in so doing distinguishes his position from that of Berkeley, who in the eighteenth century was commonly regarded as a solipsist and denier of the "external world." 4 In contra-distinction to Kant's own critical or transcendental idealism, which explains the possibility of synthetic a priori knowledge within the realm of possible experience, Berkeley is characterized as a "dogmatic" or "visionary idealist." He is judged guilty of "degrading bodies to mere illusion" (B69), of regarding things in space as "merely imaginary entities" (B274), and of holding with all "genuine idealists" that: "all knowledge through the senses and experience is i Cf. Hans Vaihinger, Commentar zu Kant's Kritik der Reinen Vernunft (Stuttgart, Berlin, Leipzig, 1892), II, 494-505. Cf. Friederich Fredericks, Der Phainomenale Idealisraus Berkeley's und Kant's (Berlin, 1871); Robert Zimmerman, "Ober Kant's Widerlegung des Idealismus yon Berkeley" (Sitzungsberichte der Akademie der Wissenschaften, Vienna, Philox.-hist. Kl.), LXVIII (1871); Gustav Dieckert, tiber dos Verhiiltnis des Berkeleyschen ldealismus zu Kantischen Vernun]tkritik (Konitz, 1888). Tiffs is a consequence of the general British tendency to view Kant in phenomenalist terms. A typical recent example is found in P. F. Strawson, The Bounds of Sense (London, 1966). Kemp Smith in his Commentary to Kant's Critique o[ Pure Reason (2nd ed., rev., 1923) takes greaZ pains to distinguish between the subjectivist strand in Kant's thought, which is essentially identical to Berkeley's position, and the genuine critical doctrine which stands side by side with it in the text. 9 Cf.

They are usually dismissed as obvious misinterpretations, due to Kant's ignorance of Berkeley's actual writings, and of his reliance upon distorted second and third hand accounts of Berkeley's thought such as is to be found in Beattie. Furthermore, this view is often supported by the philological reflection that Kant did not read English, and that Berkeley's writings were not yet available in German translation. 6 The philological argument, however, loses much of its force when we consider that there was indeed a German translation of Berkeley's Dialogues, which although apparently unknown to nineteenth century scholars, was readily accessible to Kant. This is to be found, together with a translation of Collier's Clavis Universalis and critical analyses, in a work by the professor of philosophy at Rostock, Johann Christian Eschenbach, entitled: Samlung der vornehmsten Schri[tsteller die die tFirklichkeit ihres eignen K~rpers und der ganzen Ki~rperwelt leugnen (Rostock, 1756). Furthermore, in addition to this work, which was probably known to Kant, there is Berkeley's important Latin work, De Motu (1721), as well as French translations of many of... (shrink)

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

'Mr Bennett, as was to be expected, has written a first-rate book on Kant's Analytic. It is vivid, entertaining, and extremely instructive. It will be found of absorbing interest both by those who already know the Critique and by those - if there are any such - who have a developed interest in philosophy, yet no direct acquaintance with Kant. These last it will surely drive to the text and, as surely, will drive them to approach it in a truly (...) philosophical spirit. Bennett's Kant is not a giant immersed, or frozen, in time. He is a great contemporary - a little out of touch, admittedly, with recent developments in mathematics and physics - but one with whom we can all argue, against him, at his side, or obliquely to him. And so Bennett does argue, continuously, fiercely, and fruitfully; and summons to join in the argument, at appropriate moments, those older contemporaries, Locke, Leibniz, Berkeley, and Hume, and those younger contemporaries, Wittgenstein, Ryle, Ayler, Quine, Quinton, Warnock, and others. This is splendid, and a necessary corrective to that extraordinary isolation in which Kant tends to be islanded, partly indeed, by his own unique qualities, but partly by oceans of the wrong kind of respect. Bennett, continuously engaging his great antagonist, shows the right kind.'. (shrink)

Kant was centrally concerned with issues in the philosophy of natural science throughout his career. The Metaphysical Foundations of Natural Science presents his most mature reflections on these themes in the context of both his 'critical' philosophy, presented in the Critique of Pure Reason, and the natural science of his time. This volume presents a new translation, by Michael Friedman, which is especially clear and accurate. There are explanatory notes indicating some of the main connections between the argument of the (...) Metaphysical Foundations and the first Critique - as well as parallel connections to Newton's Principia. The volume is completed by an historical and philosophical introduction and a guide to further reading. (shrink)

According to Kant, “mathematical knowledge is the knowledge gained by reason from the construction of concepts.” In this paper, I shall make a few suggestions as to how this characterization of the mathematical method is to be understood.

In the modern discussions about possibility of synthetic a priori propositions, the theory of definition has a fundamental importance, because the most definition’s theories hold that analytic judgments are involved by explicit definition. However, for Kant –first author who pointed out the distinction between analytic and synthetic propositions–many analytic judgments are made by analysis of concepts which need not first be established by definition. Moreover, for him not all a priori knowledge is analytic. The statement that not all analytic judgment (...) is derived from definition and possibility of synthetic a priori knowledge, indicates Kant didn’t believe, contrary to modern theories about analytic judgment, the definition is an essential ground of knowledge.

Wittgenstein remarks in the "Tractatus" that the eye is not in the visual field. I question the claim of Michael Dummett and P T Geach that reflection on this remark helps one conceive of an observer perceiving objects in space without having any location in that space. The literal meaning of "point of view" is illustrated by the visual field. Reflection on the fact that the point of view is not itself normally an object of sight is no help in (...) conceiving perception from no point of view. (shrink)
