11. Another instance.
A man receives a sensible injury from another, thinks on the man and that action over and
over, and by ruminating on them strongly, or much, in his mind, so cements those two ideas together, that he
makes them almost one; never thinks on the man, but the pain and displeasure he suffered comes into his mind
with it, so that he scarce distinguishes them, but has as much an aversion for the one as the other. Thus hatreds are
often begotten from slight and innocent occasions, and quarrels propagated and continued in the world.
