“From the first the progress of man has been slowly but surely from the artificial to the natural, from the arbitrary and chimerical to the simple and scientific. Getting himself and his affairs more and more into natural currents and following them, this is the way man has progressed.”

The Educational Theory of Immanuel Kant (1904)
Context: Man has his own inclinations and a natural will which, in his actions, by means of his free choice, he follows and directs. There can be nothing more dreadful than that the actions of one man should be subject to the will of another; hence no abhorrence can be more natural than that which a man has for slavery. And it is for this reason that a child cries and becomes embittered when he must do what others wish, when no one has taken the trouble to make it agreeable to him. He wants to be a man soon, so that he can do as he himself likes.

Civilized Man's Eight Deadly Sins (1973)

“ Princeton for the Nation's Service http://books.google.com/books?id=9vQtAQAAIAAJ&pg=PA1326&dq=%22It+has+never+been+natural%22” (21 October 1896)
1890s
Context: It has never been natural, it has seldom been possible, in this country for learning to seek a place apart and hold aloof from affairs. It is only when society is old, long settled to its ways, confident in habit, and without self-questioning upon any vital point of conduct, that study can affect seclusion and despise the passing interests of the day.

More Worlds Than One: The Creed of the Philosopher and the Hope of the Christian (1856), "Religious Difficulties", p. 157-158
Context: The history of the human species is the history of a variety of races in every stage of civilization and barbarism, and the great majority of which have neither an intellectual, nor a moral, nor a religious progressive history. Progression has not been the character of the history of man. Without alluding to his primeval fall from his high estate, we have only to cast our eyes over the globe, and look at the intellectual, moral, and religious catastrophes which it presents to us, — at ages of light and darkness, — at alternations of progress and decline, — at the highest civilization sinking into the lowest barbarism. Mark those eastern lands, now involved in darkness, from which the beams of knowledge first radiated on mankind. Study the extinction of morality in many regions of the earth where its great lessons were first taught by our Saviour and His apostles; and above all, mark the total suppression of the Christian faith in European communities, where it has been displaced by a religion whose doctrines were preached by conquest, and whose decalogue was dictated by the sword.

Mutual Aid: A Factor of Evolution (1902)
Context: As to the sudden industrial progress which has been achieved during our own century, and which is usually ascribed to the triumph of individualism and competition, it certainly has a much deeper origin than that. Once the great discoveries of the fifteenth century were made, especially that of the pressure of the atmosphere, supported by a series of advances in natural philosophy — and they were made under the medieval city organization, — once these discoveries were made, the invention of the steam-motor, and all the revolution which the conquest of a new power implied, had necessarily to follow... To attribute, therefore, the industrial progress of our century to the war of each against all which it has proclaimed, is to reason like the man who, knowing not the causes of rain, attributes it to the victim he has immolated before his clay idol. For industrial progress, as for each other conquest over nature, mutual aid and close intercourse certainly are, as they have been, much more advantageous than mutual struggle.
