Cicero, De Finibus 5. 43
“There is certainly seems to be natural power for humans for attaining every kind of virtue and for these reasons small children are motivated by the attraction of virtues whose seeds they possess without teaching. These are surely the fundamental aspects of human nature which increase and grow as if planted. This is because we are made in such a way at birth that we already possess the basic impulses of doing something, of loving some people, and with qualities of liberality, and giving things. We also receive spirits which reach toward knowledge, wisdom, and bravery, already disinclined toward the opposites.
It is not without reason that we see those things I have mentioned in children like little sparks of virtue from which the philosopher’s reason must be kindled—the child must find their way to nature’s end by following their divine guide. As I have often said in the early period when our minds are still weak, we see nature’s power as if through fog. But once the mind progresses and gets stronger, it recognizes the power of its nature, that it may still proceed further and has become only half-finished on its own.”
Est enim natura sic generata vis hominis ut ad omnem virtutem percipiendam facta videatur, ob eamque causam parvi virtutum simulacris quarum in se habent semina sine doctrina moventur; sunt enim prima elementa naturae, quibus auctis virtutis quasi germen efficitur. Nam cum ita nati factique simus ut et agendi aliquid et diligendi aliquos et liberalitatis et referendae gratiae principia in nobis contineremus atque ad scientiam, prudentiam, fortitudinem aptos animos haberemus a contrariisque rebus alienos, non sine causa eas quas dixi in pueris virtutum quasi scintillas videmus, e quibus accendi philosophi ratio debet, ut eam quasi deum ducem subsequens ad naturae perveniat extremum. Nam ut saepe iam dixi in infirma aetate imbecillaque mente vis naturae quasi per caliginem cernitur; cum autem progrediens confirmatur animus, agnoscit ille quidem naturae vim, sed ita ut progredi possit longius, per se sit tantum inchoata.
