30 Does it not occur to you to reflect and to examine in whose domain you live? On whose property you are? Whose is that earth which you till? whose is that air which you inhale, and return again in breathing? Whose fountains do you abundantly enjoy? Whose water? Who has regulated the blasts of the wind? Who has contrived the watery clouds? Who has discriminated the productive powers of seeds by special characteristics? Does Apollo give you rain? Does Mercury send you water from heaven? Has Aesculapius, Hercules, or Diana devised the plan of showers and of storms? And how can this be, when you give forth that they were born on earth, and that at a fixed period they received vital perceptions? For if the world preceded them in the long lapse of time, and if before they were born nature already experienced rains and storms, those who were born later have no right of rain-giving, nor can they mix themselves up with those methods which they found to be in operation here, and to be derived from a greater Author.
