For man, it is not to be doubted, may by art exempt himself in part from the influence of the heavens, it being the common opinion that the heavens give an inclination by do not impel us, for which reason the learned say that a wise man rules the stars. I was born with a very choleric dispostition, in so much as there was no living with me; but I took notice of it, and considered that a person swayed by his passion at certain times be no better than a madman—I mean at those times when he suffers his passions to predominate, because he then renounces his reason and understanding. I therfore resolved to make my choleric dispostion give way to reason; so that now, though born choleric, I never suffer anger entirely to overcome me. The man who is naturally of a bad constitution may, in like manner, by dint of reason and a sober life, live to a great age and in good health, as I have done, who had normally the worst, so that it was impossible I should live above forty years, whereas I now find myself sound and hearty at the age of eighty-six; and were it not for the long and violent fits of illness which I experienced in my youth to such a degree that the physicians gave me over, and which robbed me of my radical moisture, a loss absolutely irreparable, I might expect to attain the above mentioned term of one hundred. But I know for good reasons that it is impossible, and therefore do not htink of it. It is enough for me that I have lived forty-six years beyond the term I had a right to expect, and that during this so long a respite all my senses have continued perfect, and even my teeth, my voice, my memory, and my strength. But what is still more, my brain is more itself now than it ever was. Nor do any of these powers abate as I advance in years; and this is because, as I grow older, I lessen the quantity of my solid food.
