”NO; but talk to me about other things; for upon this I am determined." What other things? What is of greater consequence than to convince you that it is not sufficient to be determined, and to persist? This is the tension of a madman, not of one in health. “I will die if you compel me to this." Why so, man: what is the matter?—"I am determined." I have a lucky escape that you are not determined to kill me. "I take no money." Why so? "I am determined." Be assured that with that very tension which you now make use of to refuse it, you may very possibly, hereafter, have as unreasonable a propensity to take it; and again to say, "I am determined." As in a distempered and rheumatic body the humour tends sometimes to one part, sometimes to another; thus it is uncertain which way a sickly mind will incline. But if to its inclination and bent an obstinate tension be likewise added, the evil then becomes desperate and incurable.
