CHAPTER VII.
OF SIMPLE IDEAS OF BOTH SENSATION AND REFLECTION.
1.

Ideas of Pleasure and Pain.
There be other simple ideas which convey themselves into the mind by all the ways of sensation and reflection, viz.

PLEASURE or DELIGHT, and its opposite, PAIN, or UNEASINESS; POWER; EXISTENCE; UNITY mix with almost all our other Ideas.
2.

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.
