The Critique of Pure Reason By Immanuel Kant

The Critique of Pure Reason by Immanuel Kant, (first published in 1781, second edition 1787), is one of the most influential works in the history of philosophy. 2] Also referred to as Kant's First Critique, it was followed by the Critique of Practical Reason (1788) and the Critique of Judgment (1790). In the preface to the first edition Kant explains what he means by a critique of pure reason: "I do not mean by this a critique of books and systems, but of the faculty of reason in general, in respect of all knowledge after which it may strive independently of all experience." Dealing with questions concerning the foundations and extent of human knowledge, Kant builds on the work of empiricist philosophers such as John Locke and David Hume, as well as taking into account the theories of rationalist philosophers such as Gottfried Wilhelm Leibniz and Christian Wolff. Kant expounds new ideas on the nature of space and time, and claims to solve the problem which Hume posed regarding human knowledge of the relation of cause and effect, and to have assessed the ability of the human mind to engage in metaphysics. Knowledge independent of experience is referred to by Kant as "a priori" knowledge, while knowledge obtained through experience is termed "a posteriori". 3] According to Kant, "a priori" knowledge expresses necessary truths. Statements which are necessarily true cannot be negated without becoming false. Examples provided by Kant include the propositions of mathematics, propositions "from the understanding in its quite ordinary employment", 4] such as "Every alteration must have a cause", as well as propositions from "natural science (physics)", such as "in all changes in the material world the quantity of matter remains unchanged". 5] Kant believed that he had discovered another attribute of propositions, which allowed him to frame the problem of a priori knowledge in a new way: the distinction between "analytic" and "synthetic" judgments. 6] According to Kant, to say that a sentence is "analytic" is to say that what is stated in the predicate-concept of the sentence is already contained (albeit covertly) in the subject-concept of that sentence. 7] The example he provides is the sentence, "All bodies are extended", which is "analytic" since the predicate-concept ("extended") is already contained in - or "thought in" - the subject-concept of the sentence ("bodies"). Kant considered the judgment, "All bodies are heavy" synthetic, since "I do not include in the concept of body in general the predicate 'weight'". 8] Synthetic judgments therefore add something to a concept, whereas analytic judgments only explain what is already contained in the concept. The distinctive character of "analytic" judgments was therefore that they can be known to be true simply by an analysis of the concepts contained in them - or, alternatively, are true by definition. Prior to Kant, it was thought that all necessary truth had the character of being "analytic". Kant argued that not all necessary truths are analytic, but that some of them are synthetic. Having explained that the basis of analytic judgments lies in the principle of contradiction, (or the principle of identity), the task he set out to achieve in the Critique of Pure Reason was to explain the grounds of those judgments which are necessary and synthetic - and these he termed "a priori synthetic judgments".

The Critique of Pure Reason by Immanuel Kant and translated by J. M. D. Meiklejohn. The Critique of Pure Reason is a book by Immanuel Kant that has exerted an enduring influence on Western philosophy. Also referred to as Kant's First Critique, it was followed by the Critique of Practical Reason (1788) and the Critique of Judgment (1790). In the preface to the first edition Kant explains that by a critique of pure reason he means not "a critique of books and systems, but of the faculty of reason in general, in respect of all knowledge after which it may strive independently of all experience" and that he aims to reach a decision about "the possibility or impossibility of metaphysics in general". Of the difference between Pure and Empirical Knowledge: That all our knowledge begins with experience there can be no doubt. For how is it possible that the faculty of cognition should be awakened into exercise otherwise than by means of objects which affect our senses, and partly of themselves produce representations, partly rouse our powers of understanding into activity, to compare to connect, or to separate these, and so to convert the raw material of our sensuous impressions into a knowledge of objects, which is called experience? In respect of time, therefore, no knowledge of ours is antecedent to experience, but begins with it. But, though all our knowledge begins with experience, it by no means follows that all arises out of experience. For, on the contrary, it is quite possible that our empirical knowledge is a compound of that which we receive through impressions, and that which the faculty of cognition supplies from itself (sensuous impressions giving merely the occasion), an addition which we cannot distinguish from the original element given by sense, till long practice has made us attentive to, and skilful in separating it. It is, therefore, a question which requires close investigation, and not to be answered at first sight, whether there exists a knowledge altogether independent of experience, and even of all sensuous impressions? Knowledge of this kind is called a priori, in contradistinction to empirical knowledge, which has its sources a posteriori, that is, in experience.

The foundational work of modern philosophy is Kant's The Critique of Pure Reason, published in 1781. It offers a thorough and challenging inquiry into the characteristics of human reason, including its knowledge and illusions. Kant contends that while reason is the source of some conceptions that precede experience and enable it, we are not permitted to infer anything about the natural world from these notions. The Critique brings together the two conflicting philosophical systems of rationalism and empiricism, which trace all of our knowledge back to experience and reason. The transcendental idealism of Kant suggests a third option that goes well beyond these two. Between "analytic" and "synthetic" judgments, Kant makes a distinction. Simply by analyzing the components that make up an analytical judgment, one may determine if it is true. Synthetic judgments don't actually contribute anything to a notion; they only describe what the idea already has.The Critique first drew little attention, but as time passed, it came under attack from both empiricist and rationalist critics, sparking debate. The work is seen as making a significant contribution to modern philosophical thinking.

Immanuel Kant's "The Critique of Pure Reason" remains a cornerstone of Western philosophical thought. A profound and influential work in the field of philosophy, this book presents a rigorous critique of reason itself. Kant delves into fundamental questions of metaphysics and epistemology, exploring the limits of human understanding and the nature of knowledge. As a seminal work in German philosophy, "The Critique of Pure Reason" explores the very foundations of how we perceive and interpret the world around us. Kant's exploration of logic and metaphysics challenges readers to examine the processes of reasoning and the nature of reality. This carefully prepared print edition preserves the integrity of Kant's original work, making it accessible to those seeking a deeper understanding of philosophical inquiry. It is essential reading for anyone interested in the history of philosophy and the enduring quest to understand the nature of being. This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. This work is in the public domain in the United States of America, and possibly other nations.
