Since I knew what it was to be a man, this is a pleasure I have not known. I have passed my days among a parcel of cool, designing beings, and have contracted all their suspicious manner in my own behavior. I should actually be as unfit for the society of my friends at home, as I detest that which I am obliged to partake of here. I can now neither partake of the pleasure of a revel, nor contribute to raise its jollity. I can neither laugh nor drink; have contracted a hesitating, disagreeable manner of speaking, and a visage that looks ill-nature itself; in short, I have thought myself into a settled melancholy, and an utter disgust of all that life brings with it. Whence this romantic turn that all our family are possessed with? Whence this love for every place and every country but that in which we reside—for every occupation but our own? this desire of fortune, and yet this eagerness to dissipate? I perceive, my dear sir, that I am at intervals for indulging this splenetic manner, and following my own taste, regardless of yours.
Above all things, let him never touch a romance or novel; these paint beauty in colors more charming than nature, and describe happiness that man never tastes. How delusive, how destructive, are those pictures of consummate bliss! They teach the youthful mind to sigh after beauty and happiness that never existed; to despise the little good which fortune has mixed in our cup, by expecting more than she ever gave; and, in general, take the word of a man who has seen the world, and who has studied human nature more by experience than precept; take my word for it, I say, that books teach us very little of the world.
It is a good remark of Montaigne’s, that the wisest men often hare friends with whom they do not care how much they play the fool. Take my present follies as instances of my regard.
