as the poets say; and that he should procure for himself all such things as are of a soporiferous nature, and which are effective of sluggishness and oblivion, whether they are odours, or ointments, or are liquid or solid medicines. And to the latter it is requisite to advise the use of a drink sober and without wine, food of an attenuated nature, and almost approaching to fasting; a house lucid, and participating of a subtle air and wind, and to urge him to be strenuously excited by solicitude and thought, and to prepare for himself a small and hard bed. But, whether we are naturally adapted to this, I mean to a vigilant life, so as to grant as little as possible to sleep, since we do not dwell among those who are perpetually vigilant, or whether we are designed to be in a soporiferous state of existence, is the business of another discussion, and is a subject which requires very extended demonstrations. 28. To the man, however, who once suspects the enchantments attending our journey through the present life, and belonging to the place in which we dwell; who also perceives himself to be naturally vigilant, and considers the somniferous nature of the region which he inhabits;—to this man addressing ourselves, we prescribe food consentaneous to his suspicion and knowledge of this terrene abode, and exhort him to suffer the somnolent to be stretched on their beds, dissolved in sleep. For it is requisite to be cautious, lest as those who look on the blear-eyed contract an ophthalmy, and as we gape when present with those who are gaping, so we should be filled with drowsiness and sleep, when the region which we inhabit is cold, and adapted to fill the eyes with rheum, as being of a marshy nature, and drawing down all those that dwell in it to a somniferous and oblivious condition. If, therefore, legislators had ordained laws for cities, with a view to a contemplative and intellectual life, it would certainly be requisite to be obedient to those laws, and to comply with what they instituted concerning food. But if they established their laws, looking to a life according to nature, and which is said to rank as a medium, [between the irrational and the intellectual life,] and to what the vulgar admit, who conceive externals, and things which pertain to the body to be good or evil, why should any one, adducing their laws, endeavour to subvert a life, which is more excellent than every law which is written and ordained for the multitude, and which is especially conformable to an unwritten and divine law? For such is the truth of the case.
