PROXIMATE CAUSES ARE UNSATISFACTORY; WE MUST SEEK THE ULTIMATE ONES.
2. To stop, on arriving at these causes, and to refuse further analysis, is to exhibit superficiality. This is against the advice of the sages, who advise ascending to the primary causes, to the supreme principles. For example, why, during the full moon, should the one man steal, and the other one not steal? Or, why, under the same influence of the heavens, has the one, and not the other, been sick? Why, by use of the same means, has the one become rich, and the other poor? The difference of dispositions, characters, and fortunes force us to seek ulterior causes, as indeed the sages have always done.
