Essais de Michel de Montaigne, volume 18

Few things, in comparison of what commonly affect other men, move, or, to say better, possess me: for 'tis but reason they should concern a man, provided they do not possess him. I am very solicitous, both by study and argument, to enlarge this privilege of insensibility, which is in me naturally raised to a pretty degree, so that consequently I espouse and am very much moved with very few things. I have a clear sight enough, but I fix it upon very few objects; I have a sense delicate and tender enough; but an apprehension and application hard and negligent. I am very unwilling to engage myself; as much as in me lies, I employ myself wholly on myself, and even in that subject should rather choose to curb and restrain my affection from plunging itself over head and ears into it, it being a subject that I possess at the mercy of others, and over which fortune has more right than I; so that even as to health, which I so much value, 'tis all the more necessary for me not so passionately to covet and heed it, than to find diseases so insupportable. A man ought to moderate himself betwixt the hatred of pain and the love of pleasure: and Plato sets down a middle path of life betwixt the two. But against such affections as wholly carry me away from myself and fix me elsewhere, against those, I say, I oppose myself with my utmost power. 'Tis my opinion that a man should lend himself to others, and only give himself to himself. Were my will easy to lend itself out and to be swayed, I should not stick there; I am too tender both by nature and use: "Fugax rerum, securaque in otia natus." ["Avoiding affairs and born to secure ease." --Ovid, De Trist., iii. 2, 9.…
