“The more modern war becomes, the more essential appear the basic qualities that from the beginning of history have distinguished armies from the mobs. The first of these is discipline.”

Vol. I, Ch. 11: Of the Times of the Birth and Passion of Christ
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: Thus have we in the Gospels of Matthew and John all things told in due order, from the beginning of John's preaching to the death of Christ, and the years distinguished from one another by such essential characters that they cannot be mistaken. The second Passover is distinguished from the first, by the interposition of John's imprisonment. The third is distinguished from the second, by a double character: first, by the interposition of the feast to which Christ went up, Mat. viii. 19. Luke ix. 57. and secondly, by the distance of time from the beginning of Christ's preaching: for the second was in the beginning of his preaching, and the third so long after, that before it came Christ said, from the days of John the Baptist until now, &c. and upbraided the cities of Galilee for their not repenting at his preaching, and mighty works done in all that time. The fourth is distinguished from the third, by the mission of the twelve from Christ to preach in the cities of Judea in all the interval. The fifth is distinguished from all the former by the twelve's being returned from preaching, and continuing with Christ during all the interval, between the fourth and fifth, and by the passion and other infallible characters.

Book 7; Variant translation: No enterprise is more likely to succeed than one concealed from the enemy until it is ripe for execution.
Nothing is of greater importance in time of war than in knowing how to make the best use of a fair opportunity when it is offered.
Few men are brave by nature, but good discipline and experience make many so.
Good order and discipline in an army are more to be depended upon than ferocity.
As translated by Neal Wood (1965)
The Art of War (1520)
Context: No proceeding is better than that which you have concealed from the enemy until the time you have executed it. To know how to recognize an opportunity in war, and take it, benefits you more than anything else. Nature creates few men brave, industry and training makes many. Discipline in war counts more than fury.

Introductory
A Treatise on Man and the Development of His Faculties (1842)
Context: It is a remarkable fact in the history of science, that the more extended human knowledge has become, the more limited human power, in that respect, has constantly appeared. This globe, of which man imagines the haughty possessor, becomes, in the eyes of astronomer, merely a grain of dust floating in immensity of space: an earthquake, a tempest, an inundation, may destroy in an instant an entire people, or ruin the labours of twenty ages.... But if each step in the career of science thus gradually diminishes his importance, his pride has a compensation in the greater idea of his intellectual power, by which he has been enabled to perceive those laws which seem to be, by their nature, placed for ever beyond his grasp.
