VIII. The kingdom of _Cosmosia_ is the world, which is the signification of the Greek word _Cosmos_. _Solidina_ is experience, and _Idearia_ imagination. These names are very properly suited, both to the characters and doctrines of the parties. Experience _solidly_ proves her maxims, by sensible and clear demonstrations; and imagination, grounds her opinions on the vain representation of her _ideas_. Solidina was a long while banished, and during all that time, Idearia reigned triumphant; for from the period that Pythagoras reduced all philosophy to his numbers, Plato to his ideas, and Aristotle to his precisions; and for many ages afterwards, the world knew no other but an ideal physic; nor did it pay the least attention, to the experimental or solid. In the first maxims of Idearia, we perceive many of the dogmas of the peripatetic doctrine, and in her second, many of the Cartesian ones; and they gave the name of Papyratius to the broacher of this last system, because the French word _Carte_, signifies the same as the Latin word _Papyrus_, from whence the appellative was derived. Des Cartes is ranged among the auditors of Idearia, because he was disposed instead of less, rather more than the Peripatetics, to regulate all physics by imagination and ideas. At length the mistake of this method was perceived, and Solidina was recalled from the villages to the city; and experiment and observation, which for a long time had only been in use among the rustics, and employed in the business of husbandry, to increase the product of the earth, improve the mountainous land, and to encourage the propagation, and mend the breed of herds and cattle; were not long since introduced in pomp, and countenanced by some courts, in the neighbourhood of which, academies were instituted, to examine nature by their help; and as the most celebrated of these, were the Academy of Sciences at Paris, and the Royal Society of London, which were founded under the protection of the kings of France and England, they called the two princes who were the lovers and patrons of Solidina, by the names of Galindo, and Anglosio, which were derived from the Latin words _Gallia_, and _Anglia_, which in that language signify France and England.
