22. You err, my opponent says, and are deceived; for the gods are not themselves artificers, but suggest these arts to ingenious men, and teach mortals what they should know, that their mode of life may be more civilized. But he who gives any instruction to the ignorant and unwilling, and strives to make him intelligently expert in some kind of work, must himself first know that which he sets the other to practise. For no one can be capable of teaching a science without knowing the rules of that which he teaches, and having grasped its method most thoroughly. The gods are, then, the first artificers; whether because they inform the minds of men with knowledge, as you say yourselves, or because, being immortal and unbegotten, they surpass the whole race of earth by their length of life.744 Lit., “by the long duration of time.” This, then, is the question; there being no occasion for these arts among the gods, neither their necessities nor nature requiring in them any ingenuity or mechanical skill, why you should say that they are skilled,745 Lit., “skilled in notions”—perceptionibus; for which præceptionibus, i.e., “the precepts of the different arts,” has been suggested in the margin of Ursinus. one in one craft, another in another, and that individuals are pre-eminently expert746 Lit., “and have skill (sollertias) in which individuals excel.” in particular departments in which they are distinguished by acquaintance with the several branches of science?
XXII. Erras , inquit, et falleris: non enim ipsi opifices dii sunt, sed ingeniis hominum subjiciunt has artes, atque ut vita sit instructior, tradunt scienda mortalibus. Sed qui aliquam subjicit ignaro ac nescio disciplinam, solertemque hunc efficere nonnullius operis scientia contendit, sciat ipse necesse est primus id, quod alterum colere constituit. Neque enim traditor alicujus esse scientiae potis est, ut non ejus, quod tradit praecepta habeat cognita, et rationem teneat exercitatissime comprehensam. Dii ergo sunt artifices primi: sive quod, ipsi ut dicitis, subdunt 0965B scientiam mentibus: sive quod immortales, et geniti numquam, genus omne terrenum vetustate temporis 0966A antecedunt. Hoc est ergo quod quaeritur, cum sit nullus apud superos artibus his locus: neque usus illorum, neque natura deposcat ingeniosum aliquid, aut sellularium scire: cur esse dicatis in aliis alios perceptionibus gnarures, et habere solertias, in quibus singuli se vincant scientiarum cognitione discreti?
