“In each succeeding war there is a tendency to proclaim as something new the principles under which it is conducted. Not only those who have never studied or experienced the realities of war, but also professional soldiers frequently fall into the error. But the principles of warfare as I learned them at West Point remain unchanged.”

“Those who are to conduct a war cannot in the nature of things, be proper or safe judges, whether a war ought to be commenced, continued, or concluded. Thy are barred from the latter functions by a great principle in free government, analogous to that which separates the sword from the purse, or the power of executing from the power of enacting laws.”

“We must be convinced that there are no such things as 'Christian principles.' There is the Person of Christ, who is the principle of everything. But if we wish to be faithful to Him, we cannot dream of reducing Christianity to it certain number of principles (though this is often done), the consequences of which can be logically deduced. This tendency to transform the work of the Living God into a philosophical doctrine is the constant temptation of theologians, and also of the faithful, and their greatest disloyalty when they transform the action of the Spirit which brings forth fruit in themselves into an ethic, a new law, into 'principles' which only have to be 'applied.”

“War is sweet to those who have not experienced it.”

“...a life in which conduct does not fairly well accord with principles is a silly life; and that conduct can only be made to accord with principles by means of daily examination, reflection, and resolution.”

“What I could not support was "a dumb war, a rash war, a war based not on reason but on passion, not on principle but on politics".”
