Modern philosophy is a branch of philosophy that originated in Western Europe in the 17th century, and is now common worldwide. It is not a specific doctrine or school (and thus should not be confused with ''Modernism''), although there are certain assumptions common to much of it, which helps to distinguish it from earlier philosophy. The 17th and early 20th centuries roughly mark the beginning and the end of modern philosophy. How much if any of the Renaissance should be included is a matter for dispute; likewise modernity may or may not have ended in the twentieth century and been replaced by postmodernity. How one decides these questions will determine the scope of one's use of "modern philosophy." This article will focus on the history of philosophy beginning from Rene Descartes through the early twentieth century ending in Ludwig Wittgenstein. ==History of modern philosophy== The major figures in philosophy of mind, epistemology, and metaphysics during the 17th and 18th centuries are roughly divided into 2 main groups. The "Rationalists," mostly in France and Germany, argued all knowledge must begin from certain "innate ideas" in the mind. Major rationalists were Descartes, Baruch Spinoza, Gottfried Leibniz, and Nicolas Malebranche. The "Empiricists," by contrast, held that knowledge must begin with sensory experience. Major figures in this line of thought are John Locke, George Berkeley, and David Hume (These are retrospective categories, for which Kant is largely responsible.) Ethics and political philosophy are usually not subsumed under these categories, though all these philosophers worked in ethics, in their own distinctive styles. Other important figures in political philosophy include Thomas Hobbes and Jean-Jacques Rousseau. In the late eighteenth century Immanuel Kant set forth a groundbreaking philosophical system which claimed to bring unity to rationalism and empiricism. Whether or not he was right, he did not entirely succeed in ending philosophical dispute. Kant sparked a storm of philosophical work in Germany in the early nineteenth century, beginning with German idealism. The characteristic theme of idealism was that the world and the mind equally must be understood according to the same categories; it culminated in the work of Georg Wilhelm Friedrich Hegel, who among many other things said that "The real is rational; the rational is real." Hegel's work was carried in many directions by his followers and critics. Karl Marx appropriated both Hegel's philosophy of history and the empirical ethics dominant in Britain, transforming Hegel's ideas into a strictly materialist form, setting the grounds for the development of a science of society. Søren Kierkegaard, in contrast, dismissed all systematic philosophy as an inadequate guide to life and meaning. For Kierkegaard, life is meant to be lived, not a mystery to be solved. Arthur Schopenhauer took idealism to the conclusion that the world was nothing but the futile endless interplay of images and desires, and advocated atheism and pessimism. Schopenhauer's ideas were taken up and transformed by Nietzsche, who seized upon their various dismissals of the world to proclaim "God is dead" and to reject all systematic philosophy and all striving for a fixed truth transcending the individual. Nietzsche found in this not grounds for pessimism, but the possibility of a new kind of freedom. 19th-century British philosophy came increasingly to be dominated by strands of neo-Hegelian thought, and as a reaction against this, figures such as Bertrand Russell and George Edward Moore began moving in the direction of analytic philosophy, which was essentially an updating of traditional empiricism to accommodate the new developments in logic of the German mathematician Gottlob Frege. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「modern philosophy」の詳細全文を読む スポンサード リンク
