One of the great misfortunes, as also one of the great follies, of mankind, is that in all countries which we call polished, except, perhaps, China, priests concern themselves with what belongs only to philosophers. These priests interfered with regulating the year; it was, they say, their right; for it was necessary that the people should know their holy days. Thus the Chaldæan, Egyptian, Greek, and Roman priests, believed themselves mathematicians and astronomers; but what mathematics and astronomy! Whoever makes a trade of quackery cannot have a just and enlightened mind. They were astrologers, and never astronomers. The Greek priests themselves first made the year to consist only of three hundred and sixty days. Their geometricians must have informed them that they were deceived by five days and more. They, therefore, corrected their year. Other geometricians further showed them that they were deceived by six hours. Iphitus obliged them to change their Greek almanac. They added one day in four years to their faulty year; Iphitus celebrated this change by the institution of the Olympiads. They were finally obliged to have recourse to the philosopher Meton, who, combining the year of the moon with that of the sun, composed his cycle of nineteen years, at the end of which the sun and moon returned to the same point within an hour and a half. This cycle was graven in gold in the public place of Athens; and it is of this famous golden number that we still make use, with the necessary corrections. We well know what ridiculous confusion the Roman priests introduced in their computation of the year. Their blunders were so great that their summer holidays arrived in winter. Cæsar, the universal Cæsar, was obliged to bring the philosopher Sosigenes from Alexandria to repair the enormous errors of the pontiffs. When it was necessary to correct the calendar of Julius Cæsar, under the pontificate of Gregory XIII., to whom did they address themselves? Was it to some inquisitor? It was to a philosopher and physician named Lilio. When the almanac was given to Professor Cogé, rector of the university, to compose, he knew not even the subject. They were obliged to apply to M. de Lalande, of the Academy of Sciences, who was burdened with this very painful task, too poorly recompensed. The rhetorician Cogé, therefore, made a great mistake when he proposed for the prize of the university this subject so strangely expressed: "_Non magis Deo quam regibus infensa est ista quæ vocatur hodie philosophia._"--"That which we now call philosophy, is not more the enemy of God than of kings." He would say _less_ the enemy. He has taken _magis_ for _minus._ And the poor man ought to know that our academies are not enemies either to the king or God. SECTION III.
