But the truth is, that at no time of my life have I been a person to hold myself polluted by the touch or approach of any creature that wore a human shape; on the contrary, from my very earliest youth it has been my pride to converse familiarly, more socratico, with all human beings, man, woman, and child, that chance might fling in my way; a practice which is friendly to the knowledge of human nature, to good feelings, and to that frankness of address which becomes a man who would be thought a philosopher. For a philosopher should not see with the eyes of the poor limitary creature calling himself a man of the world, and filled with narrow and self-regarding prejudices of birth and education, but should look upon himself as a catholic creature, and as standing in equal relation to high and low, to educated and uneducated, to the guilty and the innocent.
