Book 1, part 1, as translated by James Legge in The Life and Works of Mencius (1875), p. 124<!--. Variant translation:
Once [Mencius] visited a king, and the king asked him, "Old teacher, how can my country profit from your presence?" Mencius immediately replied, "Why do you speak of profit, sire? Isn't there also the sense of mercy and the sense of right?"
As translated by Lin Yutang in From Pagan to Christian (1959), p. 90-->
The Mencius
Context: Mencius went to see King Huei of Liang. The king said, "Venerable sir, since you have not counted it far to come here, a distance of a thousand li, may I presume that you are provided with counsels to profit my kingdom?" Mencius replied, "Why must your Majesty use that word 'profit'? What I am provided with, are counsels to benevolence and righteousness, and these are my only topics."

Metro Weekly interview (2006)
Context: 9 to 5 made people aware of equal pay for equal work. It hasn't really happened, but it has come closer. We're aware of sexual harassment, and of course, there are very few companies that have daycare centers, which seems to me would be the most humane, positive thing to do for a worker. The worker would be more loyal, they'd be more productive. It's so crazy not to do the human thing. It seems to me to be much more profitable to do the human thing. It just makes a better society.

Context: The direction is clear, and the first step is to throw your weight around on matters of right and wrong in land-use. Cease being intimidated by the argument that a right action is impossible because it does not yield maximum profits, or that a wrong action is to be condoned because it pays. That philosophy is dead in human relations, and its funeral in land-relations is overdue.

The Dominant Idea (1910)
Context: It is not to be supposed that any one will attain to the full realization of what he purposes, even when those purposes do not involve united action with others; he will fall short; he will in some measure be overcome by contending or inert opposition. But something he will attain, if he continues to aim high.
What, then, would I have? you ask. I would have men invest themselves with the dignity of an aim higher than the chase for wealth; choose a thing to do in life outside of the making of things, and keep it in mind, — not for a day, nor a year, but for a life-time. And then keep faith with themselves! Not be a light-o'-love, to-day professing this and to-morrow that, and easily reading oneself out of both whenever it becomes convenient; not advocating a thing to-day and to-morrow kissing its enemies' sleeve, with that weak, coward cry in the mouth, "Circumstances make me." Take a good look into yourself, and if you love Things and the power and the plenitude of Things better than you love your own dignity, human dignity, Oh, say so, say so! Say it to yourself, and abide by it. But do not blow hot and cold in one breath. Do not try to be a social reformer and a respected possessor of Things at the same time. Do not preach the straight and narrow way while going joyously upon the wide one. Preach the wide one, or do not preach at all; but do not fool yourself by saying you would like to help usher in a free society, but you cannot sacrifice an armchair for it.
