The minds of all men are similar in their feelings and operations; nor can any one be actuated by any affection, of which all others are not, in some degree, susceptible.

Context

“To discover the true origin of morals, and of that love or hatred, which arises from mental qualities, we must take the matter pretty deep, and compare some principles, which have been already examined and explained. We may begin with considering a-new the nature and force of sympathy. The minds of all men are similar in their feelings and operations; nor can any one be actuated by any affection, of which all others are not, in some degree, susceptible. As in strings equally wound up, the motion of one communicates itself to the rest; so all the affections readily pass from one person to another, and beget correspondent movements in every human creature.” source
