ESSAY, ESSAYIST (Fr. _essai_, Late Lat. _exagium_, a weighing or balance; _exigere_, to examine; the term in general meaning any trial or effort). As a form of literature, the essay is a composition of moderate length, usually in prose, which deals in an easy, cursory way with the external conditions of a subject, and, in strictness, with that subject, only as it affects the writer. Dr Johnson, himself an eminent essayist, defines an essay as "an irregular, undigested piece"; the irregularity may perhaps be admitted, but want of thought, that is to say lack of proper mental digestion, is certainly not characteristic of a fine example. It should, on the contrary, always be the brief and light result of experience and profound meditation, while "undigested" is the last epithet to be applied to the essays of Montaigne, Addison or Lamb. Bacon said that the Epistles of Seneca were "essays," but this can hardly be allowed. Bacon himself goes on to admit that "the word is late, though the thing is ancient." The word, in fact, was invented for this species of writing by Montaigne, who merely meant that these were experiments in a new kind of literature. This original meaning, namely that these pieces were attempts or endeavours, feeling their way towards the expression of what would need a far wider space to exhaust, was lost in England in the course of the eighteenth century. This is seen by the various attempts made in the nineteenth century to coin a word which should express a still smaller work, as distinctive in comparison with the essay as the essay is by the side of the monograph; none of these linguistic experiments, such as _essayette_, _essaykin_ (Thackeray) and _essaylet_ (Helps) have taken hold of the language. As a matter of fact, the journalistic word _article_ covers the lesser form of essay, although not exhaustively, since the essays in the monthly and quarterly reviews, which are fully as extended as an essay should ever be, are frequently termed "articles," while many "articles" in newspapers, dictionaries and encyclopaedias are in no sense essays. It may be said that the idea of a detached work is combined with the word "essay," which should be neither a section of a disquisition nor a chapter in a book which aims at the systematic development of a story. Locke's _Essay on the Human Understanding_ is not an essay at all, or cluster of essays, in this technical sense, but refers to the experimental and tentative nature of the inquiry which the philosopher was undertaking. Of the curious use of the word so repeatedly made by Pope mention will be made below.
