Charles Alexander Eastman, The Soul of the Indian

"To the untutored sage, the concentration of population was the prolific mother of all evils, moral no less than physical. He argued that food is good, while surfeit kills; that love is good, but lust destroys; and not less dreaded than the pestilence following upon crowded and unsanitary dwellings was the loss of spiritual power inseparable from too close contact with one's fellow-men."

"The logical man must either deny all miracles or none."
