By suchlike arguments, weak and strong, as Cicero with the disease of his old age, I try to rock asleep and amuse my imagination, and to dress its wounds. If I find them worse tomorrow, I will provide new stratagems. That this is true: I am come to that pass of late, that the least motion forces pure blood out of my kidneys: what of that? I move about, nevertheless, as before, and ride after my hounds with a juvenile and insolent ardour; and hold that I have very good satisfaction for an accident of that importance, when it costs me no more but a dull heaviness and uneasiness in that part; 'tis some great stone that wastes and consumes the substance of my kidneys and my life, which I by little and little evacuate, not without some natural pleasure, as an excrement henceforward superfluous and troublesome. Now if I feel anything stirring, do not fancy that I trouble myself to consult my pulse or my urine, thereby to put myself upon some annoying prevention; I shall soon enough feel the pain, without making it more and longer by the disease of fear. He who fears he shall suffer, already suffers what he fears. To which may be added that the doubts and ignorance of those who take upon them to expound the designs of nature and her internal progressions, and the many false prognostics of their art, ought to give us to understand that her ways are inscrutable and utterly unknown; there is great uncertainty, variety, and obscurity in what she either promises or threatens. Old age excepted, which is an indubitable sign of the approach of death, in all other accidents I see few signs of the future, whereon we may ground our divination. I only judge of myself by actual sensation, not by reasoning: to what end, since I am resolved to bring nothing to it but expectation and patience? Will you know how much I get by this? observe those who do otherwise, and who rely upon so many diverse persuasions and counsels; how often the imagination presses upon them without any bodily pain. I have many times amused myself, being well and in safety, and quite free from these dangerous attacks in communicating them to the physicians as then beginning to discover themselves in me; I underwent the decree of their dreadful conclusions, being all the while quite at my ease, and so much the more obliged to the favour of God and better satisfied of the vanity of this art.
