Everything in war is very simple, but the simplest thing is difficult - Carl von Clausewitz

We maintain that the mere union of a superior understanding and the necessary feelings are not sufficient to make up resolution. There are persons who possess the keenest perception for the most difficult problems, who are also not fearful of responsibility, and yet in cases of difficulty cannot come to a resolution. Their courage and their sagacity operate independently of each other, do not give each other a hand, and on that account do not produce resolution as a result. The forerunner of resolution is an act of the mind making evident the necessity of venturing, and thus influencing the will. This quite peculiar direction of the mind, which conquers every other fear in man by the fear of wavering or doubting, is what makes up resolution in strong minds; therefore, in our opinion, men who have little intelligence can never be resolute. They may act without hesitation under perplexing circumstances, but then they act without reflection.

Beauty cannot be defined by abscissas and ordinates; neither are circles and ellipses created by their geometrical formulas.
