Here is a traditional way of thinking about human knowledge. Knowledge is a species of true belief. The crucial difference between knowledge and other kinds of true belief is that propositions that are known have a special property. Justified propositions either have intrinsic justification or else they are obtainable by means of a justification-conferring argument from other justified propositions that the knower believes. The only propositions with intrinsic justification are those that fall into one of two classes: the set of (...) a priori truths and the set of propositions recording the sensory experiences of the knower.

This paper attempts to understand kant's obscure remarks that certain parts of natural science are a priori or have something akin to an a priori status. i argue that kant does not claim that propositions of physics are fully a priori, that the notion of a proposition's being a priori "given an empirical concept" can be explicated, that kant's attempted defense of the status of parts of dynamics is deeply flawed because of his commitments about a priority, but that his (...) account of natural science contains some important insights.

Phillip R. Sloan - Performing the Categories: Eighteenth-Century Generation Theory and the Biological Roots of Kant's A Priori - Journal of the History of Philosophy 40:2 Journal of the History of Philosophy 40.2 229-253 Preforming the Categories: Eighteenth-Century Generation Theory and the Biological Roots of Kant's A Priori Phillip R. Sloan Situating Kant's philosophical project in relation to the natural sciences of his day has been of concern to several scholars from both the history of science and the history of (...) philosophy. Historians of philosophy have displayed an expanded awareness of, and interest in, the importance of the scientific context of the period in which Kant carried out his "Copernican" revolution. Most commonly among philosophers, this interest has been analyzed in relation to Kant's concerns with the foundations of mechanics, matter theory, and the epistemology of Newtonian science, with the central text of interest being the Metaphysische Anfangsgründe. On the other hand, historians of philosophy and historians of science, interested in the issues of the third Critique and in the several papers of Kant dealing with biological and anthropological issues, have emphasized the unified nature of Kant's inquiries into the natural sciences, and the importance of his continued interest in the life and human sciences alongside his interests in the foundations of the physical sciences. The effort to understand the unity of Kant's.. (shrink)

A demarcation between kant's general metaphysics (transcendental principles) and his special metaphysics is attempted, through a discussion of kant's three accounts of lawlikeness, 'transcendental', 'empirical' and 'metaphysical'. the distinctions are defended via a number of 'indicators' in kant's writings, and the 'looseness of fit' between the different types of lawlikeness is discussed.

The purpose of this work is to explain the meaning of the biological terms "generatio aequivoca, Epigenesis, Praformation" in Kant's "Critique of Pure Reason", Chapter 27, within the historical context, and to show Kant's intentions by using them. Kant used these terms as biological analogies to illustrate the different epistemological positions of Locke, Leibniz and Hume (sensualism, rational dogmatism, scepticism) to form a contrast to his own point of view: "Epigenesis" stands for apodicticity, apriority, spontaneity and productivity of the categories (...) of the intellect. This biological term allowed a dynamic imagination of knowledge as a product of pure intellect (form) and sensuality (matter). Kant defined the basic terms in his critique of the judgment (Chapter 81). (shrink)

Kants Metaphysische Anfangsgründe der Naturwissenschaft von 1786 stehen ihrem Anspruch nach zwischen einer transzendentalen Kritik der Vernunft - Kant bereitete zur selben Zeit die in wesentlichen Stücken umgearbeitete zweite Auflage der KrV vor - und der Physik als empirischer Wissenschaft. Die Notwendigkeit einer Reflexion über die Naturwissenschaft verhilft dieser Schrift heute wieder zu systematischer Relevanz, nachdem sie lange Zeit nur aus dem Blickwinkel ihrer Bedeutsamkeit für die empirische Naturwissenschaft betrachtet und infolgedessen allenfalls aus wissenschaftshistorischem Interesse rezipiert wurde.

Kein Geringerer als Arthur Schopenhauer beurteilte Kants Prolegomena als die "schönste und faßlichste aller Kantischen Hauptschriften, welche viel zu wenig gelesen wird, da sie doch das Studium seiner Philosophie außerordentlich erleichtert". Die Prolegomena von 1783 sind eine Kurzfassung der "Kritik der reinen Vernunft", deren Plan und Ergebnisse sie übersichtlich darstellen sollen. In Umkehrung der Methode der Kritik - statt der synthetischen Lehrart wird nun die analytische befolgt - nimmt Kant unter der Leitfrage "Wie sind synthetische Urteile a priori möglich?" eine (...) Inhalts-, Umfangs- und Grenzbestimmung reiner Erkenntnis vor. Orientiert am Ideal der Mathematik und der Naturwissenschaft soll der Metaphysik hinsichtlich der Gewißheit ihrer Prinzipien die Nobilitierung einer Wissenschaft zuteil werden, die ihr vor der Kritik versagt war. Damit sind die Prolegomena nicht nur eine Einführung in den Transzendentalen Idealismus Kants, sondern dokumentieren bereits die Weiterführung dieser Kritischen Philosophie, welche sich über die "Grundlegung zur Metaphysik der Sitten" (1785) sowie die "Metaphysischen Anfangsgründe der Naturwissenschaft" (1786) bis zur zweiten Auflage der Kritik (1787) und über diese hinaus fortsetzt.

The entry of time and history into biological systems of classification is perhaps the single most significant development in the history of biological systematics in the modern era. Darwin's claiming that descent is ‘… the hidden bond of connexion which naturalists have been seeking under the term of the natural system’, rather than seeing the answer in the multitude of previous attempts to resolve the problem in terms of morphological affinities, analogies, and complex relations of resemblance, marked the turning point (...) in a long search into the meaning of biological taxonomy, and allowed the development of Darwin's insights by Haeckel, Plate and others into modern phylogenetic systematics.

Kants Anthropologie (1798) galt lange als eine bloß popularphilosophische Schrift von allenfalls propädeutischem Wert. Dabei erfüllt sich die Leistung der Anthropologie keineswegs nur in einer vorphilosophischen Verständigung über das theoretische und praktische Vermögen des Menschen. Nur die anthropologische Reflexion verleiht Gewißheit, daß der Mensch "sein eigener letzter Zweck ist". Dies gibt dem Leben seinen Sinn.

The concept of similarity plays a crucial role in biology, especially in natural history. Despite its apparent familiarity it has been subject again and again to reinterpretations — it may even be stated that the main streams of theoretical thinking in the life sciences are reflected and condensed in its ever changing meaning. The changing content of the concept is analyzed from Linnaean systematics through classical morphology and comparative anatomy to Darwinian evolutionary thinking. It appears that the meaning of similarity (...) is inseparable from the function of the concept in theory, viz. its operational determination. In addition a remarkable correspondence has to be recognized between the notion of similarity and the conceptualization of an organism as the basic unit of life. (shrink)
