“I expect to gain a good deal of new light, & to get a good lift, in studying…though probably I shall be a long time about this. I could wish I went on quicker. That is I wish a human head, or my head at all events, could take in a great deal more & a great deal more rapidly than is the case; and if I had made my own head, I would have proportioned it's [sic] wishes & ambition a little more to it's [sic] capacity.”
