Fichte's reputation at the present time is in some respects a curious one. On the one hand, he is by common consent acknowledged to have exercised a dominant influence upon the development of German thought during the opening decades of the nineteenth century. Thus from a specifically philosophical point of view he is regarded as an innovator who (for good or ill) played a decisive role in transforming Kant's transcendental idealism into the absolute idealism of his immediate successors, while at a more general level he is customarily seen as having put into currency certain persuasive conceptions which contributed—less directly but no less surely—to the emergence and spread of romanticism in some of its varied and ramifying forms. On the other hand, however, it is noticeable that detailed consideration of his work has not figured prominently in the recent revival of concern with post-Kantian thought as a whole which has been manifested by philosophers of the English-speaking world. Although his name is frequently mentioned in that connection, one suspects that his books may not be so often read. In part this may be due to his particular mode of expounding his views, which at times attains a level of opacity that can make even Hegel's obscurest passages seem comparatively tractable. It is also true that Fichte's principal theoretical works—if not his semipopular writings—are largely devoid of the allusions to scientific, historical, psychological or cultural matters with which his German contemporaries were prone to illustrate their philosophical doctrines and enliven their more abstract discussions: there is a daunting aridity about much of what he wrote which can raise nagging doubts in the modern reader's mind about the actual issues that are in question. Yet the fact remains that by the close of the eighteenth century his ideas had already made a profound impact, capturing the imagination of a host of German thinkers and intellectuals. The problem therefore arises as to what preoccupations, current at the time, they owed their indubitable appeal and to what puzzles they were welcomed as proffering a solution. If these can be identified, it may become at least partially intelligible that Fichte should have been widely regarded as having provided a framework within which certain hitherto intractable difficulties could be satisfactorily reformulated and resolved. Let me accordingly begin by saying something about them.
