Using the Encyclopédie

As editors of the Encyclopédie, Diderot and D'Alembert claimed that one of the work's greatest strengths was that the knowledge it contained was useful. It was indeed, for theEncyclopédieassembled existing knowledge from a wide range of fields, making that knowledge potentially accessible to a broad readership. In addition, theEncyclopédiecontributed to creating new areas of inquiry and forming new knowledge in vast fields now called science and technology, the arts and humanities. The sheer amount of knowledge contained in the pages of theEncyclopédieis impressive enough. But what the encyclopedists aimed for was a way to put knowledge to work. What they sought above all was a way to fashion critical knowledge, the kind designed to demystify readers, to 'undeceive them' as Diderot put it, and thus to free them from the reign of superstition, doctrine, and received ideas. TheEncyclopédiedoes aim to advance the Enlightenment project in this fashion. It also contains voices that are hostile or merely indifferent to such a grandiose project. Yet ultimately, the encyclopedists are correct in their claim that theEncyclopédieprovides a stronger, more powerful way of knowing things, one more able to resist or at least to situate critically prior ways of knowing. A century and a half after the appearance of the first volume of theEncyclopédiein 1751, as we open its pages - or view them on-line or from a CD-Rom -whatthe encyclopedists knew is of less importance to us now thanhowthey knew. Or rather, to understand what theEncyclopédiepresents to its readers in the way of knowledge, we must also consider how that knowledge is to be read. For us today, the most fascinating, compelling, and challenging aspect of this daring, monumental experiment is the way it entwines what the present volume calls ways of knowing and ways of reading. Thanks to the extensive scholarship of literary and cultural historians, we now know more than ever about theEncyclopédieproject, from the socio-intellectual networks to which individual encyclopedists belonged, to the print culture networks through which their work circulated. Building on that contextual knowledge, the present volume returns to the text of theEncyclopédiein a series of essays that consider, in various ways, the encyclopedic relation to knowledge. The range of topics treated here is broad, corresponding quite naturally to the breadth of theEncyclopédieitself. But these essays call us to reflect on the twin issues of epistemology and history, exploring the questions, debates, and paradigms in terms of which critical knowledge is produced in the eighteenth century, as well as in our own.
