All of knowledge, all of science, and all
of human invention which add to material {474} comforts will be of no
avail unless men can learn to live together harmoniously and justly.
But the truths discovered in each department of investigation are all

one universe with many parts, and though man is a small particle of the

achievements.

UNIVERSAL EDUCATION AND DEMOCRACY

_Universal Public Education Is a Modern Institution_.--The Greeks
valued education and encouraged it, but only those could avail
themselves of its privileges who were able to pay for it. The training
