"Deprendas animi tormenta latentis in aegro Corpore; deprendas et gaudia; sumit utrumque Inde habitum facies." ["You may discern the torments of mind lurking in a sick body; you may discern its joys: either expression the face assumes from the mind."--Juvenal, ix. 18] The soul that lodges philosophy, ought to be of such a constitution of health, as to render the body in like manner healthful too; she ought to make her tranquillity and satisfaction shine so as to appear without, and her contentment ought to fashion the outward behaviour to her own mould, and consequently to fortify it with a graceful confidence, an active and joyous carriage, and a serene and contented countenance. The most manifest sign of wisdom is a continual cheerfulness; her state is like that of things in the regions above the moon, always clear and serene. 'Tis Baroco and Baralipton--[Two terms of the ancient scholastic logic.]--that render their disciples so dirty and ill-favoured, and not she; they do not so much as know her but by hearsay. What! It is she that calms and appeases the storms and tempests of the soul, and who teaches famine and fevers to laugh and sing; and that, not by certain imaginary epicycles, but by natural and manifest reasons. She has virtue for her end, which is not, as the schoolmen say, situate upon the summit of a perpendicular, rugged, inaccessible precipice: such as have approached her find her, quite on the contrary, to be seated in a fair, fruitful, and flourishing plain, whence she easily discovers all things below; to which place any one may, however, arrive, if he know but the way, through shady, green, and sweetly-flourishing avenues, by a pleasant, easy, and smooth descent, like that of the celestial vault. 'Tis for not having frequented this supreme, this beautiful, triumphant, and amiable, this equally delicious and courageous virtue, this so professed and implacable enemy to anxiety, sorrow, fear, and constraint, who, having nature for her guide, has fortune and pleasure for her companions, that they have gone, according to their own weak imagination, and created this ridiculous, this sorrowful, querulous, despiteful, threatening, terrible image of it to themselves and others, and placed it upon a rock apart, amongst thorns and brambles, and made of it a hobgoblin to affright people.
