A man without the proper use of the intellectual faculties of a man, is, if possible, more contemptible than even a coward, and seems to be mutilated and deformed in a still more essential part of the character of human nature.

Context

“though, perhaps, no other public good might result from such attention, besides the prevention of so great a public evil. The same thing may be said of the gross ignorance and stupidity which, in a civilized society, seem so frequently to benumb the understandings of all the inferior ranks of people. A man without the proper use of the intellectual faculties of a man, is, if possible, more contemptible than even a coward, and seems to be mutilated and deformed in a still more essential part of the character of human nature. Though the state was to derive no advantage from the instruction of the inferior ranks of people, it would still deserve its attention that they should not be altogether uninstructed. The state, however, derives no inconsiderable advantage from their instruction.” source
