Context: There must be not merely preparedness in things material; there must be preparedness in soul and mind. To prepare a great army and navy without preparing a proper national spirit would avail nothing. And if there is not only a proper national spirit, but proper national intelligence, we shall realize that even from the standpoint of the army and navy some civil preparedness is indispensable. For example, a plan for national defense which does not include the most far-reaching use and cooperation of our railroads must prove largely futile. These railroads are organized in time of peace. But we must have the most carefully thought out organization from the national and centralized standpoint in order to use them in time of war. This means first that those in charge of them from the highest to the lowest must understand their duty in time of war, must be permeated with the spirit of genuine patriotism; and second, that they and we shall understand that efficiency is as essential as patriotism; one is useless without the other.

This was the method followed by Euclid, who, fortunately for us, never dreamed of a geometry of triangles, as distinguished from a geometry of circles, or a separate application of the arithmetics of addition and subtraction; but made one help out the other as he best could.

“Experience without theory is blind, but theory without experience is mere intellectual play.”
This is declared to be "an old Kantian maxim" in General Systems Vol. 7-8 (1962), p. 11, by the Society for the Advancement of General Systems Theory, but may simply be a paraphrase or summation of Kantian ideas.
Kant's treatment of the transcendental logic in the First Critique contains a portion, of which this quote may be an ambiguously worded paraphrase. Kant, claiming that both reason and the senses are essential to the formation of our understanding of the world, writes: "Without sensibility no object would be given to us, and without understanding none would be thought. Thoughts without content are empty, intuitions without concepts are blind (A51/B75)".

“There is nothing like a parade to elicit the proper respect for the military from the populace.”
