2. Mix with almost all our other ideas.
Delight or uneasiness, one or other of them, join themselves to almost all
our ideas both of sensation and reflection: and there is scarce any affection of our senses from without, any retired
thought of our mind within, which is not able to produce in us pleasure or pain. By pleasure and pain, I would be
understood to signify, whatsoever delights or molests us; whether it arises from the thoughts of our minds, or
anything operating on our bodies. For, whether we call it satisfaction, delight, pleasure, happiness, etc., on the one
side, or uneasiness, trouble, pain, torment, anguish, misery, etc., on the other, they are still but different degrees of
the same thing, and belong to the ideas of pleasure and pain, delight or uneasiness; which are the names I shall
most commonly use for those two sorts of ideas.
