Critique of Pure Reason

Front Cover
G. Bell, 1901 - 617 pages
Metaphysicians have for centuries attempted to clarify the nature of the world and how rational human beings construct their ideas of it. Materialists believed that the world (including its human component) consisted of objective matter, an irreducible substance to which qualities and characteristics could be attributed. Mindthoughts, ideas, and perceptionswas viewed as a more sophisticated material substance. Idealists, on the other hand, argued that the world acquired its reality from mind, which breathed metaphysical life into substances that had no independent existence of their own.
These two camps seemed deadlocked until Immanuel Kant's Critique of Pure Reason endeavored to show that the most accurate theory of reality would be one that combined relevant aspects of each position, yet transcended both to arrive at a more fundamental metaphysical theory. Kant's synthesis sought to disclose how human reason goes about constructing its experience of the world, thus intertwining objective simuli with rational processes that arrive at an orderly view of nature.

About the author (1901)

The greatest of all modern philosophers was born in the Baltic seaport of Konigsberg, East Prussia, the son of a saddler and never left the vicinity of his remote birthplace. Through his family pastor, Immanuel Kant received the opportunity to study at the newly founded Collegium Fredericianum, proceeding to the University of Konigsberg, where he was introduced to Wolffian philosophy and modern natural science by the philosopher Martin Knutzen. From 1746 to 1755, he served as tutor in various households near Konigsberg. Between 1755 and 1770, Kant published treatises on a number of scientific and philosophical subjects, including one in which he originated the nebular hypothesis of the origin of the solar system. Some of Kant's writings in the early 1760s attracted the favorable notice of respected philosophers such as J. H. Lambert and Moses Mendelssohn, but a professorship eluded Kant until he was over 45. In 1781 Kant finally published his great work, the Critique of Pure Reason. The early reviews were hostile and uncomprehending, and Kant's attempt to make his theories more accessible in his Prolegomena to Any Future Metaphysics (1783) was largely unsuccessful. Then, partly through the influence of former student J. G. Herder, whose writings on anthropology and history challenged his Enlightenment convictions, Kant turned his attention to issues in the philosophy of morality and history, writing several short essays on the philosophy of history and sketching his ethical theory in the Foundations of the Metaphysics of Morals (1785). Kant's new philosophical approach began to receive attention in 1786 through a series of articles in a widely circulated Gottingen journal by the Jena philosopher K. L. Reinhold. The following year Kant published a new, extensively revised edition of the Critique, following it up with the Critique of Practical Reason (1788), treating the foundations of moral philosophy, and the Critique of Judgment (1790), an examination of aesthetics rounding out his system through a strikingly original treatment of two topics that were widely perceived as high on the philosophical agenda at the time - the philosophical meaning of the taste for beauty and the use of teleology in natural science. From the early 1790s onward, Kant was regarded by the coming generation of philosophers as having overthrown all previous systems and as having opened up a whole new philosophical vista. During the last decade of his philosophical activity, Kant devoted most of his attention to applications of moral philosophy. His two chief works in the 1790s were Religion Within the Bounds of Plain Reason (1793--94) and Metaphysics of Morals (1798), the first part of which contained Kant's theory of right, law, and the political state. At the age of 74, most philosophers who are still active are engaged in consolidating and defending views they have already worked out. Kant, however, had perceived an important gap in his system and had begun rethinking its foundations. These attempts went on for four more years until the ravages of old age finally destroyed Kant's capacity for further intellectual work. The result was a lengthy but disorganized manuscript that was first published in 1920 under the title Opus Postumum. It displays the impact of some of the more radical young thinkers Kant's philosophy itself had inspired. Kant's philosophy focuses attention on the active role of human reason in the process of knowing the world and on its autonomy in giving moral law. Kant saw the development of reason as a collective possession of the human species, a product of nature working through human history. For him the process of free communication between independent minds is the very life of reason, the vocation of which is to remake politics, religion, science, art, and morality as the completion of a destiny whose shape it is our collective task to frame for ourselves.
