I am the inferior of any man whose rights I trample under foot. Men are not superior by reason of the accidents of race or color. They are superior who have the best heart the best brain. Superiority is born of honesty, of virtue, of charity, and above all, of the love of liberty. The superior man is the providence of the inferior. He is eyes for the blind, strength for the weak, and a shield for the defenceless. He stands erect by bending above the fallen. He rises by lifting others.
Robert Green Ingersoll
Notes on the quote
This quote is the nearest match I can find for another that is widely attributed to Robert Ingersoll: “We rise by lifting others”.
