Pleasure is a shadow; wealth is vanity; and power is a pageant: but knowledge is intrinsic enjoyment, perennial fame, unlimited space, and infinite duration. In the performance of its sacred office, it fears no danger, spares no expense, omits no exertion.It scales the mountain, looks into the volcano, dives into the ocean, perforates the earth, wings its flight into the skies, encircles the globe, explores sea and land, contemplates the distant, examines the minute, comprehends the great, and ascends the sublime. No place, too remote for its grasp, no heavens, too exalted for its touch.
