Feuerbach · Friedrich Engels
INTRODUCTION.
"We also find, upon a closer enquiry, that the two poles of an antithesis, such as positive and negative, are as inseparable from as they are opposed to each other, and that, despite their antagonism, they mutually pervade each other; and in the same way we find cause and effect to be conceptions whose force exists only when applied to a single instance, but which, soon as we consider that instance in its connection with the cosmos, run into each other and dissolve in the contemplation of that universal action and reaction where cause and effect constantly change places--that which is effect, now and here, becoming, then and yonder, cause, and vice versa. "None of these processes and methods of reasoning fits in the metaphysical framework of thought. To dialectics, however, which takes in the objects and their conceivable images above all in their connections, their sequence, their motion, their rise and decline, processes like the above are so many attestations of its own method of procedure. Nature furnishes the test to dialectics, and this much we must say for modern natural science, that it has contributed towards this test an extremely rich and daily increasing material, whereby it has demonstrated that, in the last instance, nature proceeds upon dialectical, not upon metaphysical methods, that it does not move upon the eternal sameness of a perpetually recurring circle, but that it goes through an actual historic evolution.
"This new German philosophy culminated in the system of Hegel. There for the first time--and herein consists its merit--the whole natural, historic, and intellectual world was presented as a process, i. e., engaged in perpetual motion, change, transformation and development. Viewed from this standpoint, the history of mankind no longer appeared as a wild tangle of senseless deeds of violence, all equally to be rejected by a ripened philosophic judgment, and which it were best to forget as soon as possible, but as the process of the development of mankind itself--a development whose gradual march, through all its stray paths, and its eternal law, through all its seeming fortuitousness, it now became the task of the intellect to trace and to discover." Kirkup, in his "History of Socialism," has this to say upon the dialectic method of investigation as used by Marx: "In the system of Marx, it means that the business of enquiry is to trace the connection and concatenation in the links that make up the process of historic evolution, to investigate how one stage succeeds another in the development of society, the facts and forms of human life and history not being stable and stereotyped things, but the ever-changing manifestations of the fluent and unresting real, the course of which it is the duty of science to reveal." The translator has endeavored to render the meaning of the original in as simple an English form as possible, and to, generally speaking, avoid technical terms.
