It is quite an old-fashioned fallacy to suppose that our objection to scepticism is that it removes the discipline from life. Our objection to scepticism is that it removes the motive power. Materialism is not a thing which destroys mere restraint. Materialism itself is the great restraint.
Morality is neither rational nor absolute nor natural. World has known many moral systems, each of which advances claims universality; all moral systems are therefore particular, serving a specific purpose for their propagators or creators, and enforcing a certain regime that disciplines human beings for social life by narrowing our perspectives and limiting our horizons.
To invest successfully over a lifetime does not require a stratospheric IQ, unusual business insights, or inside information. What's needed is a sound intellectual framework for making decisions and the ability to keep emotions from corroding that framework. You must supply the emotional discipline.
When the leader is morally weak and his discipline not strict, when his instructions and guidance are not enlightened, when there are no consistent rules, neighboring rulers will take advantage of this.
The discipline of colleges and universities is in general contrived, not for the benefit of the students, but for the interest, or more properly speaking, for the ease of the masters. Its object is, in all cases, to maintain the authority of the master, and whether he neglects or performs his duty, to oblige the students in all cases to behave toward him as if he performed it with the greatest diligence and ability.
A sapling must be hedged about for protection, but when it becomes a tree, a hedge would be a hindrance. So there is no need to criticise and condemn the old forms.
I certainly do not adore the writer's discipline. I have lost lovers, endangered friendships, and blundered into eccentricity, impelled by a concentration which usually is to be found only in the minds of people about to be executed in the next half hour.
