2. Good and evil, what.
Things then are good or evil, only in reference to pleasure or pain. That we call good,
which is apt to cause or increase pleasure, or diminish pain in us; or else to procure or preserve us the possession
of any other good or absence of any evil. And, on the contrary, we name that evil which is apt to produce or
increase any pain, or diminish any pleasure in us: or else to procure us any evil, or deprive us of any good. By
pleasure and pain, I must be understood to mean of body or mind, as they are commonly distinguished; though in
truth they be only different constitutions of the mind, sometimes occasioned by disorder in the body, sometimes
by thoughts of the mind.
