There cannot be found in the animal kingdom a bat, or any other creature, so blind in its own range of circumstance and connection, as the greater majority of human beings are in the bosoms of their families.
The superior man is the providence of the inferior. He is eyes for the blind, strength for the weak, and a shield for the defenseless. He stands erect by bending above the fallen. He rises by lifting others.
The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, skepticism is the highest of duties; blind faith the one unpardonable sin.
