18. Grammar appeals to reason, as well as to authority, but to what extent it should do so, has been matter of dispute. "The knowledge of useful arts," says Sanctius, "is not an invention of human ingenuity, but an emanation from the Deity, descending from above for the use of man, as Minerva sprung from the brain of Jupiter. Wherefore, unless thou give thyself wholly to laborious research into the nature of things, and diligently examine the causes and reasons of the art thou teachest, believe me, thou shalt but see with other men's eyes, and hear with other men's ears. But the minds of many are preoccupied with a certain perverse opinion, or rather ignorant conceit, that in grammar, or the art of speaking, there are no causes, and that reason is scarcely to be appealed to for any thing;—than which idle notion, I know of nothing more foolish;—nothing can be thought of which is more offensive. Shall man, endowed with reason, do, say, or contrive any thing, without design, and without understanding? Hear the philosophers; who positively declare that nothing comes to pass without a cause. Hear Plato himself; who affirms that names and words subsist by nature, and contends that language is derived from nature, and not from art."
19. "I know," says he, "that the Aristotelians think otherwise; but no one will doubt that names are the signs, and as it were the instruments, of things. But the instrument of any art is so adapted to that art, that for any other purpose it must seem unfit; thus with an auger we bore, and with a saw we cut wood; but we split stones with wedges, and wedges are driven with heavy mauls. We cannot therefore but believe that those who first gave names to things, did it with design; and this, I imagine, Aristotle himself understood when he said, ad placitum nomina significare. For those who contend that names were made by chance, are no less audacious than if they would endeavour to persuade us, that the whole order of the universe was framed together fortuitously."
20. "You will see," continues he, "that in the first language, whatever it was, the names of things were taken from Nature herself; but, though I cannot affirm this to have been the case in other tongues, yet I can easily persuade myself that in every tongue a reason can be rendered for the application of every name; and that this reason, though it is in many cases obscure, is nevertheless worthy of investigation. Many things which were not known to the earlier philosophers, were brought to light by Plato; after the death of Plato, many were discovered by Aristotle; and Aristotle was ignorant of many which are now everywhere known. For truth lies hid, but nothing is more precious than truth. But you will say, 'How can there be any certain origin to names, when one and the same thing is called by different names, in the several parts of the world?' I answer, of the same thing there may be different causes, of which some people may regard one, and others, an other. * * * There is therefore no doubt, that of all things, even of words, a reason is to be rendered: and if we know not what that reason is, when we are asked; we ought rather to confess that we do not know, than to affirm that none can be given. I know that Scaliger thinks otherwise; but this is the true account of the matter."
21. "These several observations," he remarks further, "I have unwillingly brought together against those stubborn critics who, while they explode reason from grammar, insist so much on the testimonies of the learned. But have they never read Quintilian, who says, (Lib. i, Cap. 6,) that, 'Language is established by reason, antiquity, authority, and custom?' He therefore does not exclude reason, but makes it the principal thing. Nay, in a manner, Laurentius, and other grammatists, even of their fooleries, are forward to offer reasons, such as they are. Moreover, use does not take place without reason; otherwise, it ought to be called abuse, and not use. But from use authority derives all its force; for when it recedes from use, authority becomes nothing: whence Cicero reproves Coelius and Marcus Antonius for speaking according to their own fancy, and not according to use. But, 'Nothing can be lasting,' says Curtius, (Lib. iv,) 'which is not based upon reason.' It remains, therefore, that of all things the reason be first assigned; and then, if it can be done, we may
