"But though this tribunal within the breast be thus the supreme arbiter of all our action, though it can reverse the decisions of all mankind with regard to our character and conduct, and mortify us amidst the applause or support us under the censure of the world; yet, if we enquire into the origin of its institution, its jurisdiction we shall find is in a great measure derived from the authority of that very tribunal, whose decisions it so often and so justly reverses."
— Smith, Adam (1723-1790)
