“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.” source
