“In ages far remote,--of a civilisation far different from that which now merges the individual in the state,--there existed men of ardent minds, and an intense desire of knowledge. In the mighty and solemn kingdoms in which they dwelt, there were no turbulent and earthly channels to work off the fever of their minds. Set in the antique mould of casts through which no intellect could pierce, no valour could force its way, the thirst for wisdom alone reigned in the hearts of those who received its study as a heritage from sire to son. Hence, even in your imperfect records of the progress of human knowledge, you find that, in the earliest ages, Philosophy descended not to the business and homes of men. It dwelt amidst the wonders of the loftier creation; it sought to analyse the formation of matter,--the essentials of the prevailing soul; to read the mysteries of the starry orbs; to dive into those depths of Nature in which Zoroaster is said by the schoolmen first to have discovered the arts which your ignorance classes under the name of magic. In such an age, then, arose some men, who, amidst the vanities and delusions of their class, imagined that they detected gleams of a brighter and steadier lore. They fancied an affinity existing among all the works of Nature, and that in the lowliest lay the secret attraction that might conduct them upward to the loftiest. (Agreeably, it would seem, to the notion of Iamblichus and Plotinus, that the universe is as an animal; so that there is sympathy and communication between one part and the other; in the smallest part may be the subtlest nerve. And hence the universal magnetism of Nature. But man contemplates the universe as an animalcule would an elephant. The animalcule, seeing scarcely the tip of the hoof, would be incapable of comprehending that the trunk belonged to the same creature,--that the effect produced upon one extremity would be felt in an instant by the other.) Centuries passed, and lives were wasted in these discoveries; but step after step was chronicled and marked, and became the guide to the few who alone had the hereditary privilege to track their path.
