Thus tis that a Language with which we are already acquainted, either by the assistance of Art, or Conversation, leads us to an intimacy with those that were altogether unknown to us before, and that their relation redresseth the treachery of the memory in the close and juncture of one with the other.
But that I may compasse this my designe with lesse trouble, my greatest care is to make choise of one Language as a rule to measure by, and a principle to reduce all the rest too: for to pretend to compare them immediately one with another, as some would have it, is to cherish confusion among those things that demand the most of order.
The veneration that I have alwayes had for antiquity, made me think at first of ingaging for the Hebrew, as being (for ought we know) the earliest, the most noble, and most naturall Language of the world and that from which all others, in a manner, derive themselves. But it was not long before I began to consider, that this would directly crosse the first principles of my intended method, and appear a kind of indeavour to teach an unknown Language, by another, of which we have the most imperfect, and slender information of all. The kindnesse, and inclination I ought to have for my own Country, had almost perswaded me to rest my self there, and to make my native tongue the basis of this universall reduction but then the rest of the Europæan world (which I have no reason to slur or contemne) would have as ill resented the project, as we did it in the Germans, who would long agoe have challenged this honour to themselves. I had in the end no other course to take, but to throw myselfe upon the Latine, in which I luckily met with all the necessary conditions that did easily, and plausibly conduce to my design'd attempt.
To say the truth Aristotle himselfe, a man of a judgement in such things the most exact that ever was to take a measure from, demanded but three qualifications, viz. Universality, Certainty, and Proportion; that it should be generally known to all those that are to make use of it in the quality of a measure, that it should be fixt, and determin'd in its selfe, and then that it should be proportion'd to all those things, to which it prescribes their bounds, all which characters do with advantage combine in the Latine, and that with such propriety that they cannot be attributed to any other without some sort of injustice; for the greatest part of the other Languages they are determind to the extent of a particular Kingdom or Country, the Latine hath no such disadvantage upon it. It is to speak properly the Language of Europe: Religion, and the Sciences have more enlarg'd its dominions, then all the conquests of the Romans; tis almost the common Idiom of the North, and universally knowne to persons of birth and education, who alone are presum'd to stand in need of the assistance of forraigne Languages.
It disownes the common imperfection of others, which by nature being subject to change, cannot by consequence, serve for a certain determinate rule in all ages; and if it now survive through the large extent of its entertainment, it hath much the advantage of others, that are in a manner deceas'd to this that is fixt, and retaind by a well assur'd custome and if its being universally known allows all persons to share its uses, so its being steddy, and unalterable, secures it from all the uneven changes of time.
As to its proportion, it in a manner keeps a mean between the Ancient and Modern Languages, it is neither altogether so pure as the one, nor so corrupt as the other, and so with the same ease is applicable to both; and in earnest is infinitely the most compendious, it being farre less trouble to passe from the mean to an extream, or from the extream to the mean, then to trace it from one extream to another. However this would seem incommodious beyond all redresse, to attempt to reduce all the Languages, either to the most ancient, or else to any one of the most modern, because in reality, the former have no more relation to the later, then these have with others of the same age, which have been as so many channels to derive Antiquity to us.
Besides the Latin makes a friendly meeting between the Eastern, and Western Languages; as to the first alone it owes its birth and life, so the others do to it.
It seems then no more difficult to attain the one, by streaming it up to the fountain, then to gain all the rest by making a like descent, by way of resemblance to what we observe in nature when we discern, as well the effect by the cause, as the cause by the effect. In one word, to make up all the differences that may arise about the supremacie of the Languages, I consider the Latin under three different regards, as the daughter of the Languages of the East, as the Mother of those in the West, and as the Sister of the more Northerne.
As it is abundantly copious, and rich, having been refind, and improv'd for more then 3000 years by an infinite variety of nations, with whose spoyls it is now invested, so it may have a very great number of resemblances, under which with little difficultie it will admit of a reference to all the rest. For in conclusion, to reduce all to the most refin'd, and polite Language, is not what I pretend to; the Barbarous stile of the ancient Romans will do me as much service, as the quaintnesse, and elegance of Cicero; the Latin of the declining Empire, since the irruptions of the Northern Nations, may be admitted into this designe to as good purpose, as the language of Augustus his time; any sense is the same of that of the Sciences, which makes one almost altogether distinct from what is common and vulgar; the proper names of Philosophy, naturall History, and Divinity, those of Physick, and the Mathematicks, of Arts, Law, and Commerce; the names of illustrious persons, people and places, of which History furnisheth us with a plausible account, will afford me no lesse assistance on this occasion, then the names of things that are most common.
After having made choice of a Language in order to the design, I am in the next place to determine my self to a certain number of them, the reunion of which may be justly thought a modest and reasonable attempt; for as there are some, the knowledge of which will be of very little use; so I am obliged to prescribe some bounds to a designe that would lead me to something indetermin'd, and infinite, and withall I suspect the inlargement both of mind, and memory to compasse all; especially considering the consequence of some to be indifferent, neither that of Biscany, nor the lower Brettaigne should in my opinion much afflict any mans braine, nor do I believe that there are many more in the world interest for them, then there are for the dialect of Finland or Frizland, or the Barbarous jangling of the Negroes and Savages. In the choise that I was to make I could not but give the preference to those of the greatest credit and repute, took some Prince (excuse the allusion) who having laid his design to reunite all the Kingdomes of the world, began his conquest upon those Nations that were most formidable and renown'd, from an apprehension that the rest in a little time would be less able to make any opposition.
