“Where knowledge is a duty, ignorance is a crime.”

“Ignorance is of a peculiar nature; once dispelled, it is impossible to reestablish it. It is not originally a thing of itself, but is only the absence of knowledge; and though man may be kept ignorant, he cannot be made ignorant.”

“Whatever is my right as a man is also the right of another; and it becomes my duty to guarantee as well as to possess.”

“Reason obeys itself; and ignorance submits to whatever is dictated to it.”

“I believe in the equality of man, and I believe that religious duties consist of doing justice, loving mercy, and endeavoring to make our fellow-creatures happy.”

“He that would make his own liberty secure must guard even his enemy from oppression; for if he violates this duty he establishes a precedent that will reach to himself.”

“I believe in one God, and no more; and I hope for happiness beyond this life. I believe in the equality of humans; and I believe that religious duties consist in doing justice, loving mercy, and endeavoring to make our fellow creatures happy.”
