Reality

"Sooner or later Time brings the empty phrase and the false conclusion up against what is; the empty imaginary looks reality in the face and the truth at once conquers. In war a nation learns whether it is strong or no, and how it is strong and how weak; it learns it as well in defeat as in victory. In the long processes of human lives, in the succession of generations, the real necessities and nature of a human society destroy any false formula upon which it was attempted to conduct it. Time must always ultimately teach."
~Hilaire Belloc
