Curiosity is, in great and generous minds, the first passion and the last; and perhaps always predominates in proportion to the strength of the contemplative faculties. He who easily comprehends all that is before him, and soon exhausts any single subject, is always eager for new inquiries; and, in proportion as the intellectual eye takes in a wider prospect, it must be gratified with variety by more rapid flights, and bolder excursions; nor perhaps can there be proposed to those who have been accustomed to the pleasures of thought, a more powerful incitement to any undertaking, than the hope of filling their fancy with new images, of clearing their doubts, and enlightening their reason. When Jason, in Valerius Flaccus, would incline the young prince Acastus to accompany him in the first essay of navigation, he disperses his apprehensions of danger by representations of the new tracts of earth and heaven, which the expedition would spread before their eyes; and tells him with what grief he will hear, at their return, of the countries which they shall have seen, and the toils which they have surmounted: _O quantum terrae, quantum cognoscere coeli Permissum est! pelagus quantos aperimus in usus! Nunc forsan grave reris opus: sed laeta recurret Cum ratis, et caram cum jam mihi reddet Iolcon; Quis pudor heu nostros tibi tunc audire labores! Quam referam visas tua per suspiria gentes!_ ARG. Lib. i. 168. Led by our stars, what tracts immense we trace! From seas remote, what funds of science raise! A pain to thought! but when the heroick band Returns applauded to their native land, A life domestick you will then deplore, And sigh while I describe the various, shore. EDW. CAVE. Acastus was soon prevailed upon by his curiosity to set rocks and hardships at defiance, and commit his life to the winds; and the same motives have in all ages had the same effect upon those whom the desire of fame or wisdom has distinguished from the lower orders of mankind. If, therefore, it can be proved that distress is necessary to the attainment of knowledge, and that a happy situation hides from us so large a part of the field of meditation, the envy of many who repine at the sight of affluence and splendour will be much diminished; for such is the delight of mental superiority, that none on whom nature or study have conferred it, would purchase the gifts of fortune by its loss. It is certain, that however the rhetorick of Seneca may have dressed adversity with extrinsick ornaments, he has justly represented it as affording some opportunities of observation, which cannot be found in continual success; he has truly asserted, that to escape misfortune is to want instruction, and that to live at ease is to live in ignorance.
