As the Knowledge of forreign Languages ought not to be reputed one of those vain and useless curiosities that serve only to amuse the mind, but is certainly conducive to a thousand different ends; so we ought not to think it strange if our age, which gives such aequall and secure judgement of the value of things shew more of passion then ever for it, notwithstanding all the difficulties that are pretended. I am of an opinion, that one cannot do the world a more acceptable piece of service, then to invent a certain and easie way to become universally acquainted with the Languages, and to quit a subject from those intrigues, in which the more knowing have at present involv'd it, either from a pure impotence to disingage it, or possibly from a fond desire of a freer breath of popular Air from those who are ordinarily most taken with what they least understand. This designe being only a proper entertainment for the most criticall of the Virtuoses, I am the more inclinable to expose to the public, the project and plain I have form'd, before I intirely abandon the whole to their censure; that I may at first anticipate all manner of reply, and take advantage from the lights of the most accomplisht and intelligent persons, if their zeale hath courage enough to make them willing to serve the world in their love and communication. _The Authors designe._ Most men being prepossest with two unjust prejudices against the nature of the Languages, th'one, that they have not all either resemblance or accord among them, the other, that they only depend upon the inconstancie of chance, and the whisling toyishness of custome, it might be thought no matter of extraordinary concernment, if one pretended to succeed in a study of this nature by the single efforts of the memory, without either the vivacitie of imagination, or the force of reason being interress'd. But being not very well perswaded of the agreeableness of this method, in direct opposition to it, I have fastn'd the whole designe in hand upon these two propositions: First, that _there is a certain accord between the Severall Languages:_ and that therefore they are attainable by comparison. Secondly, _they are unquestionably founded upon reason_, and therefore that must be made use of in their mutuall reference. It is upon these two foundations that I pretend to establish the true method of gaining a mastery of the Languages, making it appear to the world by a sensible experience that the mind can as easily make reflections upon words, as upon the things they represent: _Imagination_ and _Reason_ being the two faculties, that can reflect upon their objects, they both will appear in the present designe in their uses suitable to their nature, the effects of _Imagination_ shall be visible in the severall resemblances, and the inferences that are thence made; and it will be the worke of _Reason_ to reduce all to certain principles, upon which the argumentative part must relye.
