“The industrial peak of a people when its main concern is not yet gain, but rather to gain.”

1770s, African Slavery in America (March 1775)
Context: TO AMERICANS. THAT some desperate wretches should be willing to steal and enslave men by violence and murder for gain, is rather lamentable than strange. But that many civilized, nay, christianized people should approve, and be concerned in the savage practice, is surprising; and still persist, though it has been so often proved contrary to the light of nature, to every principle of Justice and Humanity, and even good policy, by a succession of eminent men, and several late publications.

The Evolution of Modern Capitalism: A Study of Machine Production (1906), Ch. XVII Civilisation and Industrial Development
Context: History does not show greed of gain as the motive of the great steps in industrial progress. The love of science, the pure delight of mechanical invention, the attainment of some slight personal convenience in labour, and mere chance, play the largest part in the history of industrial improvements. These motives would be as equally operative under state-control as under private enterprise.<!--section 11, p. 419

Faliero, Act V. Sc. 2.
Marino Faliero (1885)
Context: Farewell, and peace be with you if it may.
I have lost, ye have won this hazard: yet perchance
My loss may shine yet goodlier than your gain
When time and God give judgment. If there be
Truth, true is this, that I desired the right
And ye with hands as red sustain the wrong
As mine had been in triumph. Have your will:
And God send each no bitterer end than mine.

Part 4, XXVIII (1886)
Meditations of a Parish Priest (1866)

Response to the question: "I have listened to you for many years and I have become quite good at watching my thoughts and being aware of every thing I do, but I have never touched the deep waters or experienced the transformation of which you speak. Why?"
1950s, Freedom From the Self (1955)
Context: The questioner wants to know why, after these many years of watching, he hasn't found the deep waters. Why should he find them? Do you understand? You think that by watching your own thoughts you are going to get a reward: if you do this, you will get that. You are really not watching at all, because your mind is concerned with gaining a reward. You think that by watching, by being aware, you will be more loving, you will suffer less, be less irritable, get something beyond; so your watching is a process of buying. With this coin you are buying that, which means that your watching is a process of choice; therefore it isn't watching, it isn't attention. To watch is to observe without choice, to see yourself as you are without any movement of desire to change, which is an extremely arduous thing to do; but that doesn't mean that you are going to remain in your present state. You do not know what will happen if you see yourself as you are without wishing to bring about a change in that which you see. Do you understand?

Context: Our merchants and master-manufacturers complain much of the bad effects of high wages in raising the price, and thereby lessening the sale of their goods both at home and abroad. They say nothing concerning the bad effects of high profits. They are silent with regard to the pernicious effects of their own gains. They complain only of those of other people.
