I think that you have heard all this 'from yourself, and not from me'; nor did I say this, which you erroneously attribute to me, but you yourself, and what you said was very true. For indeed, my dear fellow, the design which you meditate of teaching what you do not know, and have not taken any pains to learn, is downright insanity.
