text: Your desire, however, that I should dispatch to you my own writings does not make me think myself learned, any more than a request for my picture would flatter my beauty. I know that it is due to your charity rather than to your judgment. And even if it is the result of judgment, it was charity that forced the judgment upon you. But whatever the quality of my works may be, read them as if I were still seeking, and were not aware of, the truth, and were seeking it obstinately, too. For I have sold myself to no man; I bear the name of no master. I give much credit to the judgment of great men; but I claim something also for my own. For these men, too, have left to us, not positive discoveries, but problems whose solution is still to be sought. They might perhaps have discovered the essentials, had they not sought the superfluous also. They lost much time in quibbling about words and in sophistical argumentation; all that sort of thing exercises the wit to no purpose. We tie knots and bind up words in double meanings, and then try to untie them.
