Petrarch, On His Own Ignorance (32):
“I don’t say these things in an effort to avoid their judgment, but so that they who are ignorant may feel some shame (if they are capable of it) in making their judgment. For, on this subject, I do not just embrace the opinion of friendly jealousy, but even the judgment of hostile hatred, and in sum, if someone pronounces that I am ignorant, I agree with him! When I myself think over how many things are lacking to me, toward which my mind, eager for knowledge, exerts itself, I sadly and silently recognize my own ignorance. But in the meantime, while the end of my present exile is near, at which point this imperfection (from whence our knowledge derives) will be terminated, I am consoled by the thought of our shared nature. I think that it happens to all good and modest minds, that they learn about themselves and derive consolation therefrom. For those who get hold of great knowledge (I am speaking according to the standards of human learning), it is always small when considered in itself, but it becomes great in light of the narrow circumstances from which it is derived, and certainly looks great when compared to others. Otherwise, I ask you, how small and insignificant is the knowledge granted to one mind? Nay, how much like nothing is the knowledge of any one person, whoever they be, when it is compared not just to the knowledge of God, but to one’s own fund of ignorance?”
Non hec dico, ut declinem forum, sed ut pudeat, siquis est pudor, iudicasse qui nesciunt. Ego etenim de hac re non modo sententiam amicabilis amplector invidie, sed hostilis odii, et ad summam, quisquis ignarum me pronuntiat, mecum sentit. Nam et ego ipse recogitans quam multa michi desint ad id quo sciendi avida mens suspirat, ignorantiam meam dolens ac tacitus recognosco. Sed me interim, dum presentis exilii finis adest, quo nostra hec imperfectio terminetur, qua ex parte nunc scimus, nature communis extimatione consolor. Idque omnibus bonis ac modestis ingeniis evenire arbitror, ut agnoscant se pariter ac solentur; his etiam quibus ingens obtigit scientia — secundum humane scientie morem loquor — que in se semper exigua, pro angustiis quibus excipitur, et collata aliis ingens fit. Alioquin quantulum, queso, est, quantumcunque est, quod nosse uni ingenio datum est? Imo quam nichil est scire hominis, quisquis sit, si non dicam scientie Dei, sed sui ipsius ignorantie comparetur?
