When I contemplate the common lot of mortality, I must acknowledge that I have drawn a high prize in the lottery of life. The far greater part of the globe is overspread with barbarism or slavery: in the civilized world, the most numerous class is condemned to ignorance and poverty; and the double fortune of my birth in a free and enlightened country, in an honourable and wealthy family, is the lucky chance of an unit against millions. The general probability is about three to one, that a new-born infant will not live to complete his fiftieth year. [Note: Buffon, Supplement a l'Hist. naturelle, vii. p, 158-164, of a given number of new-born infants, one half, by the fault of nature or man, is extinguished before the age of puberty and reason,--a melancholy calculation!] I have now passed that age, and may fairly estimate the present value of my existence in the three-fold division of mind, body, and estate. 1. The first and indispensable requisite of happiness is a clear conscience, unsullied by the reproach or remembrance of an unworthy action. --Hic murus aheneus esto, Nil conscire sibi, nulla pallescere culpa. I am endowed with a cheerful temper, a moderate sensibility, and a natural disposition to repose rather than to activity: some mischievous appetites and habits have perhaps been corrected by philosophy or time. The love of study, a passion which derives fresh vigour from enjoyment, supplies each day, each hour, with a perpetual source of independent and rational pleasure; and I am not sensible of any decay of the mental faculties. The original soil has been highly improved by cultivation; but it may be questioned, whether some flowers of fancy, some grateful errors, have not been eradicated with the weeds of prejudice. 2. Since I have escaped from the long perils of my childhood, the serious advice of a physician has seldom been requisite. "The madness of superfluous health" I have never known; but my tender constitution has been fortified by time, and the inestimable gift of the sound and peaceful slumbers of infancy may be imputed both to the mind and body. 3. I have already described the merits of my society and situation; but these enjoyments would be tasteless or bitter if their possession were not assured by an annual and adequate supply. According to the scale of Switzerland, I am a rich man; and I am indeed rich, since my income is superior to my expence, and my expence is equal to my wishes. My friend Lord Sheffield has kindly relieved me from the cares to which my taste and temper are most adverse: shall I add, that since the failure of my first wishes, I have never entertained any serious thoughts of a matrimonial connection?
