Benjamin M. Anderson, The Value of Money
“ The mind grasps such a notion with difficulty, if at all. Logic is mechanical and mathematical, and mathematics and mechanics are static. [592] But further, we may in large measure bring the historical considerations into a cross-section picture, when it is a value system that is involved. Past facts exert their influence through present values; and future facts, which may be expected to modify future values, come into the present equilibrium as discounted present worths. ”
