"But in all such matters that which appears to the good man is thought to be really so." (i.e. that which appears good to him) Aristotle,'Nichomachean Ethics' Bk.10.chap.V.
Wisdom and Truth can often be connatural with persons who know nothing of abstruse philosophy and ethical theory. The only explanation is that they are it. A Nisargadatta or a Ramakrishna is more impressive than a hyper educated Brahmin but of course 'it' can land anywhere.
From War and Peace:
"Oh, well, of course, folks are different. One man lives for his own wants and nothing else, like Mituh, he only thinks of filling his belly, but Fokanitch, is a righteous man. He lives for his soul. He does not forget God."
"How thinks of God? How does he live for his soul?" Levin almost shouted.
"Why, to be sure, in truth, in God's way. Folks are different. Take you now, you wouldn't wrong a man ......"
"Yes, yes, good-bye!" said Levin, breathless with excitement, and turning round he took his stick and walked quickly away towards home. At the peasant's words that Fokanitch lived for his soul, in truth, in God's way, undefined but significant ideas seemed to burst out as though they had been locked up, and all striving towards one goal, they thronged whirling through his head, blinding him with their light.
