"By the word Strong-Passion, I mean a passion the object of which is so necessary to our happiness, that without the possession of it life would be insupportable. This was Omar's idea of the passion, when he said, 'Whoever thou art, that lovest liberty, desirest to be wealthy without riches, powerful without subjects, a subject without a master, dare to condemn death: kings will then tremble before thee, whilst thou alone shalt fear no person.'.... It was the passion of honor and philosophic fanaticism alone that could induce Timicha, the Pythagorean, in the midst of torture, to bite off her tongue, that she might not expose herself to reveal the secrets of her sect. Cato, when a child, going with his tutor to Sylla's palace, at seeing the bloody heads of the proscribed, asked with impatience the name of the monster who had caused so many Roman citizens to be murdered. He was answered, it was Sylla: 'How,' says he, 'does Sylla murder thus, and is Sylla still alive?' 'Yes,' it was replied, 'the very name of Sylla disarms our citizens.' 'Oh! Rome,' cried Cato, 'deplorable is thy fate, since within the vast compass of thy walls not a man of virtue can be found, and the arm of a feeble child is the only one that will oppose itself against tyranny!' Then, turning towards his governor, 'Give me,' said he, 'your sword; I will conceal it under my robe, approach Sylla, and kill him. Cato lives, and Rome is again free.' If the generous pride, the passion of patriotism and glory, determine citizens to such heroic actions, with what resolution and intrepidity do not the passions inspire those who aim at distinction in the arts and sciences, and whom Cicero calls the peaceable heroes? It is from a desire of glory that the astronomer is seen, on the icy summits of the Cordileras, placing his instruments in the midst of snows and frost; which conducts the botanist to the brinks of precipices in quest of plants; which anciently carried the juvenile lovers of ihe sciences into Egypt, Ethiopia, and even into the Indies, for visiting the most celebrated philosophers, and acquiring from their conversation the principles of their doctrine. How strongly did this passion exert itself in Demosthenes, who, for perfecting his pronunciation, used every day to stand on the sea-shore, and with his mouth full of pebbles harangue the agitated waves! It was from the same desire of glory that the young Pythagoreans submitted to a silence of three years, in order to habituate themselves to recollection and meditation; it induced Democritus to shun the distractions of the world, and retire among the tombs, to meditate on those valuable truths, the discovery of which, as it is always very difficult, is also very little esteemed; in fine, it was this that prompted Heraclitus to cede to his younger brother the throne of Ephesus, to which he had the right of primogeniture, that he might give himself up entirely to philosophy;
