Encyclopedism is not restricted to the history of encyclopedias as we now know them. Certainly, since the eighteenth century, this identification has been the dominant one; however, the term encyclopedism is best seen as a heuristic device that can legitimately be applied to other intellectual projects. Three main forms of encyclopedism can be discerned: first, the classical Greek and Roman notion of a circle of learning that an educated person should pursue; second, various schemes aimed at comprehensive collection and classification of an intellectual field or an aspect of the world; and third, the aim of condensing and summarizing knowledge from a wide range of subjects in a set of volumes, variously called compendium, dictionary, or encyclopedia.

The Circle of Learning

We owe the word encyclopaedia to Quintilian's (first century c.e.) Latinized version of the Greek term denoting a circle of learning. Works such as Marcus Terentius Varro's Disciplines (c. 50 b.c.e., now lost) defined this circle as the "seven liberal arts," which later formed the trivium and quadrivium of the medieval university curriculum. Varro also included medicine and architecture. However, the circle of learning, comprising selected subjects, must be distinguished from the circle of all knowledge. A similar outlook is found in authors of the Middle Ages who placed the classical learning within a Christian framework, seeking to document the knowledge required by man for salvation. Important examples of such works are Flavius Magnus Cassiodorus's Institutiones (c. 560 c.e.), Isidore of Seville's Etymologiae (636), and Hugh of St. Victor's Didascalicon (c. 1130). Including both sacred and secular learning, these works expanded the original Greek concept; indeed, in Isidore there are hints of encyclopedism as near-comprehensive coverage of knowledge, including topics outside the liberal arts.

The most famous of the medieval works was the Speculum maius (The greater mirror), compiled between 1245 and 1260 from a range of authorities by the Dominican friar Vincent of Beauvais; it was reprinted as late as 1624. It comprised three books, or mirrorsof nature, of history, and of doctrine. The last book, the Speculum doctrinale (Mirror of doctrine), covered the liberal and mechanical arts, mathematics, and natural philosophy. Gregor Reisch's Margarita philosophica (The philosophic pearl), first published in Freiburg in 1496, is one of the most successful examples of an encyclopedic compendium. Reisch summarized arts and sciences in the university curriculum of his day and implied a sequence of disciplines, sometimes by matching subjects to particular stages of life. This work went through ten editions between 1503 and 1599. At the other end of the Renaissance period Johann Heinrich Alsted's (15881638) Encyclopaedia (4 vols, 1630), considered the last and best of the neo-Scholastic encyclopedias, treated thirty disciplines in separate treatises arranged in accordance with a philosophical schema; in addition, an index to each treatise allowed access to a specific discipline. Yet even such a large work was conceived as a summary of subjects that in principle outlined an educational path. Alsted described his work as presenting a "methodological understanding of everything than man must learn in this life" (book 1).

Who could truly encompass this circle of knowledge? Indeed there were already doubts, especially given Francis Bacon's (15611626) stress on new knowledge, steadily accumulating over time. Nevertheless, the idea of "encyclopaedia" revived by Renaissance humanists was still selective, conceived as a circle of learning, not a summary of all knowledge in a single work. A version of this ideal supported the notion of general learning in the arts curriculum of the early modern European universities. In the English case, for example, this included rhetoric, logic, mathematics, and moral and natural philosophy. This curriculum was predicated on the interdependence of various branches of knowledge, a conviction elaborated by the Cambridge mathematician and divine, Isaac Barrow (16301677), who advised that "one Part of Learning doth confer Light to another, that he will be a lame Scholar, who hath not an insight into many kinds of knowledge, that he can hardly be a good Scholar, who is not a general one" (Barrow, vol. 1, p. 184). In his Glossographia of 1656 Thomas Blount (16181679) reflected this position by defining the "encyclopedy" as "that learning which comprehends all Liberal Sciences; an Art that comprehends all others, the perfection of all knowledge."

Encyclopedic Collections

Pliny the Elder's Naturalis historia (77 c.e.) is often cited as an early encyclopedic work. His thirty-seven books and 2,493 chapters collated information from over four hundred authors, offering (in his estimate) some twenty thousand facts about the natural history of animals, objects, and techniques. However, Pliny was not concerned with the unity of knowledge or the relations between disciplines. Instead, he managed to give "encyclopedia" a wider denotation by announcing in his opening epistle that the Greeks meant by this a complete body of arts and sciences. Pliny thereby forged a link between natural history and the notion of encyclopedism imagined as comprehensiveness. During the Renaissance the Natural History came to be seen as a museum catalog, a shopping list for assembling a cabinet of curiosities. Moreover, the activity of collecting was informed by the ideal of encyclopedic learning. By possessing rare or otherwise valuable objects, an individual collector displayed his knowledge of them, their classical literary associations, and their place in a larger schema, such as the Great Chain of Being. The polymath Athanasius Kircher (16011680) established a museum in the Jesuit College in Rome and regarded it as his "enciclopedia concreta" (actual or tangible encyclopedia). Gabriel Naudé, in his Advis pour dresser une bibliothèque (1627; Instruction concerning establishing a library), declared that a library should represent the encyclopedic circle of learning. The architecture of the buildings (museums and libraries) that held such treasures was often seen as a physical expression of the encyclopedia, now increasingly regarded as a model or microcosm of divine creation.

Eventually, however, large collections began to tell against the notion of the individual collector as knowing his possessions as one might be said to know the seven liberal arts. Sir Hans Sloane's (16601753) private collection (the founding collection of the British Museum) comprised some forty thousand books, three thousand manuscripts, and two hundred thousand objects, such as coins and medals, natural history, anthropological specimens, and other curious items. Such collections were often called "encyclopedic," but this now indicated that they were so extensive as to be beyond the capacities of a single mind, or memory. By at least the early 1700s critics were saying that once a collection reached a certain size, its value must be found in the various uses different people might make of it. Encyclopedism, in this guise, severed its link with the notion of the "encyclopedia" as a path of individual learning.

It is also possible to consider encyclopedism as supporting the notion of virtual collections. Conrad Gesner's (15161565) Bibliotheca universalis (1545; Universal library) was a bibliography of all known bookseighteen hundred authors and ten thousand titlesrather than a catalog of any existing library. During the eighteenth century, attempts to classify books, objects, or aspects of natureeven if not held in any collectionwere regarded as encyclopedic because they allowed a large number of things to be comprehended by a single person, independent of being actually seen or touched. This is how the taxonomies of the plant and animal worlds, such as those of Carolus Linnaeus (17071778), were understood and promoted.

In German universities from the eighteenth century, particular disciplines were given "encyclopedic" arrangements, so that encyclopedias of philology, law, and medicine were offered as introductory and summary courses within particular departments. As Henri Abrams wrote in his Encyclopédie juridique (1855; Juridical encyclopedia), "An encyclopedia may be regarded in general as a synthetic plan embracing a science in all its parts."

Alphabetical Encyclopedias

By the early 1700s, a new expression of encyclopedism was the publication of encyclopedias in the form of alphabetical dictionaries of terms and subjects. These were regarded as summaries of accumulated information in various fields of knowledge, produced in a form accessible to a wide readership. Such works acknowledged the medieval and Renaissance legacy of encyclopedism, but the scope of these new works extended beyond the subjects of the university and also explicitly confronted the problem of keeping pace with the incessant progress of knowledge in all fields.

Distinctions must be made within the set of alphabetical dictionaries that emerged toward the end of the seventeenth century. By 1700 there were specialist lexicons for anatomy, chemistry, and other subjects; the predecessors of the modern language dictionary; the historical (and biographical) dictionary; and the dictionary of arts and sciences. The last two kinds are most relevant here because for a time the distinction between them had a bearing on the contemporary definition of an encyclopedia. Louis Moréri's Grand Dictionnaire Historique (Great historical dictionary), first published in Lyon in 1674 and then issued in an expanded second edition in 1681, is usually regarded as the first work (other than bibliographies) to summarize a range of subjects in strictly alphabetical order. Pierre Bayle's Dictionnaire historique et critique (2 vols., 1697; enlarged 2nd ed., 1702; Critical and historical dictionary,) began as an attempt to remedy Moréri's errors. Although large works for their time, neither pretended to the title of "encyclopaedia" because they were conceived as historical dictionaries covering major aspects of sacred and secular history by means of biographical entries on key figures.

The new genre of the dictionary of arts and sciences was the more direct predecessor of the modern encyclopedia. Three significant examples are Antoine Furetière's (16191688) Dictionnaire universel, published in three volumes at the Hague in 1690, two years after his death; John Harris's Lexicon technicum (2 vols., 1704, 1710); and Ephraim Chambers's (16801740) Cyclopaedia (2 vols., 1728). These works consisted of entries on terms (mainly from the arts and sciences) in alphabetical order, but they professed to be more than definitions of words by also being descriptions of things. The category of "arts and sciences" was flexible enough to embrace apparently disparate subjects such as law, music, and architecture, as well as the disciplines of the physico-mathematical disciplines and the new experimental sciences. The Lexicon technicum was strong on the latter but far less comprehensive than Chambers's Cyclopaedia, which justified its use of that title by covering systematic disciplines belonging to the category "scientia" such as grammar, theology, logic, music, astronomy, mechanics, optics, and other parts of natural philosophy, as well as of subjects capable of being brought into scientific order, such as anatomy, medicine, natural history, and the practical and mechanical arts and trades. It did not include biography or history. Thus early-eighteenth-century encyclopedism tolerated a division of laborbetween historical/biographical dictionaries and those dealing with the arts and sciences (and assuming the title of encyclopedia). The Grosses vollständiges Universal-Lexicon aller Wissenschaften und Künste (Great, complete universal lexicon of all sciences and arts ), begun in 1732 by the Leipzig publisher Johann Zedler, is an example of an historical dictionary that included entries on scientific topics in addition to those on history, theology, philosophy, and biography; it reached sixty-four folio volumes by 1750. By at least the early 1800s, encyclopedic coverage meant a comprehensive survey of all knowledge of the kind attempted by the Encyclopaedia Britannica, especially in its ninth edition (25 vols, 18751889).

Chambers compiled his Cyclopaedia single-handedly, drawing from various sources and presenting the information under key terms. With the famous Encyclopédie (17511780), edited by Denis Diderot (17131784) and Jean Le Rond d'Alembert (17171783), encyclopedism became collaborative. While acknowledging their debt to Chambers, the French editors declared that a complete survey of knowledge required the efforts of many hands and so recruited contributions from leading members of the Republic of Letters. When completed, the Encyclopédie consisted of seventeen folio volumes of text and eleven volumes of plates, incorporating an extensive documentation of the arts, crafts, and trades, and illustrated by some twenty-five hundred engravings. Whereas Chambers's sought to condense "the vast bulk of universal knowledge into a lesser compass" (Chambers, 1738, vol. 1, xxiv), the French editors welcomed long essays covering the history and current views on a particular subject. This set the pattern for subsequent encyclopedias. The Encyclopaedia Britannica (3 vols., 1771) departed from Chambers's format of relatively short entries on terms, instead presenting major disciplines as "systems" in separate treatises of at least twenty-five pages each. From its third edition (10 vols., 17881797) experts were invited to write these treatises. Similarly, the Encyclopédie methodique (166 vols., 17821832), the successor to the Encyclopédie, was organized by disciplines, so that, for example, there were at least nine volumes on natural history. Each subject was under the control of a leading expert with a license (almost without a word limit) to describe and codify a field. Previously a concept that assumed the value of general learning, encyclopedism now depended on specialists.

This shift had implications for the rationale of Enlightenment encyclopedias. Both Chambers and Diderot claimed that the integrity of particular sciences and the relations between them could still be perceived, in spite of alphabetical arrangement. This is why they provided maps or charts of knowledge in their prefaces, albeit recognizing that such classification was to some degree arbitrary. Given the expansion of knowledge, especially in the natural sciences, they admitted that there was no longer a single circle of learning (such as the seven liberal arts) but insisted that their works were informed by an awareness of the links between subjects and that cross references allowed the reader to follow these in a methodical fashion. By the late 1700s, however, most encyclopedias had abdicated responsibility for any systematic classification of the subjects they covered. The Britannica never included a map of knowledge. One exception was the Encyclopaedia metropolitana (26 vols, 18271845), organized on a plan devised by the English poet Samuel Taylor Coleridge. This was a return to the systematic, or at least thematic, format of earlier encyclopedic works. Rejecting alphabetical arrangement, Coleridge recommended an order of subjects that reflected the hierarchy of the disciplines in the classification he supplied, beginning with the abstract, formal subjects of logic, grammar, and geometry (all in the first two volumes), then the mixed-mathematical disciplines such as astronomy, optics, and music; then the various parts of natural history, and so on. This sequence of subjects was intended to prescribe a proper order of study. But this format had limited appeal, and the work was a commercial failure. Encyclopedism had finally lost touch with the original sense of the Greek concept of a circle of learning that an individual could, and should, pursue.

Nevertheless, understood as comprehensive coverage of either a single subject or the totality of knowledge, encyclopedism still flourished into the twentieth century. The nationalist emphasis of the nineteenth century (replacing the cosmopolitanism of the Enlightenment) continued to inspire encyclopedias. In various European countries, and in the Soviet Union, encyclopedias were emblems of national culturefor example, the Enciclopedia Italiana (19291939) in thirty-six large volumes, directed, in part, by the philosopher Giovanni Gentile. Other manifestations include H. G. Wells's call for a new encyclopedia to function as the "World Brain," and the International Encyclopedia of Unified Science a collection of monographs planned by members of the Vienna Circle, notably by Otto Neurath (18921945) and Rudolf Carnap (18911970). In the late twentieth and early twenty-first centuries, the electronic storage and retrieval of information has allowed vast collection projects, larger than anything earlier versions of encyclopedism had contemplated.

By the late twentieth century, the role of encyclopedias in textual form was being questioned. The Encyclopaedia Britannica was issued on CD-ROM and then online; but with the increasing power of search engines on the Internet, the reference function of encyclopedias has been challenged. The tradition of encyclopedism in the West has emphasized the importance of categories of knowledge, relations between subjects, and the authority and credibility of the selections and summaries contained in catalogs, taxonomies, museums, and encyclopedias. Regardless of the medium in which information is stored in the twenty-first century, these issues remain.
