Pythagoras likewise inculcated the famous numerical system of the monad, dyad, and triad; and by means of his sacred quaternary, elucidated the formation of the world, the arcana of nature, and the principles both of music and morals.[11] Other sages adhered to the mathematical system of squares and triangles; the cube, the pyramid, and the sphere; the tetrahedron, the octahedron, the icosahedron, and the dodecahedron.[12] While others advocated the great elementary theory, which refers the construction of our globe and all that it contains to the combinations of four material elements, air, earth, fire, and water; with the assistance of a fifth, an immaterial and vivifying principle.
Nor must I omit to mention the great atomic system taught by old Moschus before the siege of Troy; revived by Democritus of laughing memory; improved by Epicurus, that king of good fellows; and modernized by the fanciful Descartes.

But I decline inquiring, whether the atoms, of which the earth is said to be composed, are eternal or recent; whether they are animate or inanimate; whether, agreeably, to the opinion of Atheists, they were fortuitously aggregated, or, as the Theists maintain, were arranged by a supreme intelligence.[13] Whether, in fact, the earth be an insensate clod, or whether it be animated by a soul,[14] which opinion was strenuously maintained by a host of philosophers, at the head of whom stands the great Plato, that temperate sage, who threw the cold water of philosophy on the form of sexual intercourse, and inculcated the doctrine of Platonic love--an exquisitely refined intercourse, but much better adapted to the ideal inhabitants of his imaginary island of Atlantis than to the sturdy race, composed of rebellious flesh and blood, which populates the little matter-of-fact island we inhabit.
Besides these systems, we have, moreover, the poetical theogony of old Hesiod, who generated the whole universe in the regular mode of procreation; and the plausible opinion of others, that the earth was hatched from the great egg of night, which floated in chaos, and was cracked by the horns of the celestial bull.

To illustrate this last doctrine, Burnet, in his theory of the earth,[15] has favored us with an accurate drawing and description, both of the form and texture of this mundane egg, which is found to bear a marvelous resemblance to that of a goose.

Such of my readers as take a proper interest in the origin of this our planet will be pleased to learn that the most profound sages of antiquity among the Egyptians, Chaldeans, Persians, Greeks, and Latins have alternately assisted at the hatching of this strange bird, and that their cacklings have been caught, and continued in different tones and inflections, from philosopher to philosopher, unto the present day.
But while briefly noticing long celebrated systems of ancient sages, let me not pass over, with neglect, those of other philosophers, which, though less universal than renowned, have equal claims to attention, and equal chance for correctness.

Thus it is recorded by the Brahmins in the pages of their inspired Shastah, that the angel Bistnoo transformed himself into a great boar, plunged into the watery abyss, and brought up the earth on his tusks.
