War seems to be ingrained in human nature, and even to be regarded as something noble to which man is inspired by his love of honor, without selfish … - Immanuel Kant

...Ethical laws cannot be thought of as emanating originally merely from the will of this superior being as statutes, which, had he not first commanded them, would perhaps not be binding, for then they would not be ethical laws and the duty proper to them would not be the free duty of virtue but the coercive duty of law.

What might be said of things in themselves, separated from all relationship to our senses, remains for us absolutely unknown

Reason in a creature is a faculty of widening the rules and purposes of the use of all its powers far beyond natural instinct; it acknowledges no limits to its projects. Reason itself does not work instinctively, but requires trial, practice, and instruction in order gradually to progress from one level of insight to another. Therefore a single man would have to live excessively long in order to learn to make full use of all his natural capacities. Since Nature has set only a short period for his life, she needs a perhaps unreckonable series of generations, each of which passes its own enlightenment to its successor in order finally to bring the seeds of enlightenment to that degree of development in our race which is completely suitable to Nature’s purpose. This point of time must be, at least as an ideal, the goal of man’s efforts, for otherwise his natural capacities would have to be counted as for the most part vain and aimless. This would destroy all practical principles, and Nature, whose wisdom must serve as the fundamental principle in judging all her other offspring, would thereby make man alone a contemptible plaything.
