our tongue, whose physicking I like not this way, and therefore I will join close with my own observation to see if that will help. Those men who will give any certain direction for the writing of any tongue, or for anything else that concerns a tongue, must take some period in its history, or else their rules will prove inapplicable. For every tongue has a certain ascent from the lowest to the highest point, and a descent again from the highest to the lowest; and as in the ascent it has not reached a secure position, because it is not thoroughly reduced to art, so in the descent it comes to be not worth noting, because it gets rude again, and in a manner withered. Hence it comes that the age of Demosthenes is the prince of Greece, as that of Cicero is the flower of Rome, and if the languages of these countries had not been committed to the security of books, they would have been of little worth; nay, they would have been forgotten altogether, long before our day, as the spoken tongues of those nations, changing continually since the periods named, are now quite altered, or at least are nothing like what they were in their prime, though still blooming in another form. So that books give life where bodies bring only death. Consider the Greek and Latin writers before the ages of those men, and by comparing them with these, you will see the difference that I spoke of, the earlier being too rude to be brought under rule, and the later departing from established rules and yielding to change. This period of full development, with the ascent to it and the decline leading to decay, shows us that everything belonging to man is subject to change, the language changing also, but never dying out. It must needs be therefore that there is something of the nature of a soul in every spoken tongue that feeds this change even with perceptible means. For if any tongue be fixed, and free from movement, it is enshrined in books, not subject to ordinary use, but made immortal by the register of memory.
