This life may be compared to the Olympic Games, for, as in this assembly, some ask glory and the crowns; some by the purchase or by the sale of merchandise seek gain; and others, more noble than either, go there neither for gain nor for applause, but solely to enjoy this wonderful spectacle, and to see and know all that passes. We, in the same manner, quit our country, which is Heaven, and come into the world, which is an assembly where many work for profit, many for gain, and where there are but few who, despising avarice and vanity, study nature. It is these last whom I call Philosophers; for as there is nothing more noble than to be a spectator without any personal interest, so in this life the contemplation and knowledge of nature are infinitely more honorable than any other application.
