Philo Judaeus Quod Omnis Probus Liber Sit 63

[63] for it does not follow, that although the souls of such as contradict those virtuous men are deprived of all liberty for having been completely led away and enslaved by folly and other vices, that on this account the whole human race is so too. But it is no wonder if we do not see numerous companies of those men advancing as it were in a solid body. In the first place, because whatever is exceedingly beautiful is rare; secondly, because men who are removed from the main crowd of inconsiderately judging persons, have abundant leisure for the contemplation of the things of nature, endeavouring, as far as it may be in their power, to correct life in general (for virtue is a thing of great benefit to the whole community); but when they are unable to succeed in their object, by reason of the numbers of absurdities which are continually impeding them in the different cities, which the different passions and vices of the soul have given strength to, they then retire into solitude, in order not to be carried away by the violence and rush of these absurdities, as by a wintry torrent.
