“Let us be well assured that it is to physiology that it belongs to determine the causes of the most elevated phænomena, and that happiness consists, above all things, in the science of the heavenly things and their nature, and in the knowledge of analogous phænomena which may aid us in the comprehension of the ethics. These heavenly phænomena admit of several explanations; they have no reason of a necessary character, and one may explain them in different manners. In a word, they have no relation—a moment’s consideration will prove this by itself—with those imperishable and happy natures which admit of no division and of no confusion. As for the theoretical knowledge of the rising and setting of the stars, of the movement of the sun between the tropics, of the eclipses, and all other similar phænomena, that is utterly useless, as far as any influence upon happiness that it can have. Moreover, those who, though possessed of this knowledge, are ignorant of nature, and of the most probable causes of the phænomena, are no more protected from fear than if they were in the most complete ignorance; they even experience the most lively fears, for the trouble, with which the knowledge of which they are possessed inspires them, can find no issue, and is not dissipated by a clear perception of the reasons of these phænomena.
“As to us, we find many explanations of the motions of the sun, of the rising and setting of the stars, of the eclipses and similar phænomena, just as well as of the more particular phænomena. And one must not think that this method of explanation is not sufficient to procure happiness and tranquillity. Let us content ourselves with examining how it is that similar phænomena are brought about under our own eyes, and let us apply these observations to the heavenly objects and to everything which is not known but indirectly. Let us despise those people who are unable to distinguish facts susceptible of different explanations from others which can only exist and be
