“Just Discourse: Do not bandy words with your father, nor treat him as a dotard, nor reproach the old man, who has cherished you, with his age.”

Nor age can chill, nor rival steal,
Nor falsehood disavow.”

India's Rebirth
Context: India of the ages is not dead nor has she spoken her last creative word; she lives and has still something to do for herself and the human peoples. And that which must seek now to awake is not an anglicised oriental people, docile pupil of the West and doomed to repeat the cycle of the occident's success and failure, but still the ancient immemorable Shakti recovering her deepest self, lifting her head higher towards the supreme source of light and strength and turning to discover the complete meaning and a vaster form of her Dharma.

Referring to Mr. Burns. Compare to Heart of Darkness' manager: "He was becoming confidential now, but I fancy my unresponsive attitude must have exasperated him at last, for he judged it necessary to inform me he feared neither God nor devil, let alone any mere man. I said I could see that very well..."
The Shadow Line (1915)

Introductory
A Treatise on Man and the Development of His Faculties (1842)

Context: I am speaking of the life of a man who knows that the world is not given by his fathers, but borrowed from his children; who has undertaken to cherish it and do it no damage, not because he is duty-bound, but because he loves the world and loves his children; whose work serves the earth he lives on and from and with, and is therefore pleasurable and meaningful and unending; whose rewards are not deferred until "retirement," but arrive daily and seasonally out of the details of the life of their place; whose goal is the continuance of the life of the world, which for a while animates and contains them, and which they know they can never compass with their understanding or desire.
The Unforeseen Wilderness : An Essay on Kentucky's Red River Gorge (1971), p. 33; what is likely a paraphrase of a portion of this has existed since at least 1997, and has sometimes become misattributed to John James Audubon: A true conservationist is a man who knows that the world is not given by his fathers, but borrowed from his children.
