William Shakespeare's Richard III:
"My conscience hath a thousand several tongues, And every tongue brings in a several tale, And every tale condemns me for a villain."

William Whewell:
"As science means knowledge, conscience etymologically means self-knowledge . . . But the English word implies a moral standard of action in the mind as well as a consciousness of our own actions. . . . Conscience is the reason, employed about questions of right and wrong, and accompanied with the sentiments of approbation and condemnation."

ATLL and i presume many others:
"Conscience = Con-Science"
