Vincent Cronin on Alberti in his essay “The Humanists,” Horizon magazine, Vol. XIII, No. 1, Winter 1971:
Alberti did make his mark—as a writer, architect, painter, sculptor, and musician. Such versatility is a distinguishing characteristic of the humanists and another essential ingredient of their ideal man. In part versatility was a practical expression of the tremendous energy released through the study of the classical world, but it must also be seen as a reaction against the pigeonholing of earlier centuries. The medieval division of mankind into oratores, bellatores, laboratores (those who pray, those who make war, those who work with their hands) is well known, and within the latter category men were subdivided by the guild system into armorers, masons, furriers, and the like. These distinctions had been unknown in the ancient world, in which Aeschylus, as is proudly inscribed on his tomb, fought at Marathon, and in which Socrates was known not only as a philosopher but also a sculptor. The humanists returned eagerly to this classical concept, and set no bounds to the skills one man might master.
Versatility went hand in hand with a markedly amateur attitude. Alberti did things for the love of it—one might almost say for the hell of it. Florence never had a university and distrusted the attitude that had once sought to count the angels on a pinhead and now, in less humane cities, tried to count the number of imperfect subjunctives in Thucydides. It was reported of Cicero that he had never been a professional philosopher and that he conducted his philosophical meditations in the corridors of the law courts: “He philosophized most when he seemed to be doing so least.” That became a catch phrase in Florence, and a kind of deal.
In 1469 Alberti wrote a masterpiece of moral philosophy, the De Iciarchia. Here are some quotations from this little-known book:
If you are idle you might as well be asleep: you are neither wholly alive nor wholly dead.
Man is born to be useful to his fellows. And the purpose of all his skills is simply the service of others.
We must so conduct ourselves that when evening comes we have no resource to say, “Today I learned nothing, today I acquired no graceful accomplishment, today I did nothing useful for a friend, nothing that gave me enjoyment.”
Believe me, a man who is eloquent will easily make others carry out his wishes.
