18. These instances to show how our ideas of the passions are got from sensation and reflection.
I would not be
mistaken here, as if I meant this as a Discourse of the Passions; they are many more than those I have here named:
and those I have taken notice of would each of them require a much larger and more accurate discourse. I have
only mentioned these here, as so many instances of modes of pleasure and pain resulting in our minds from
various considerations of good and evil. I might perhaps have instanced in other modes of pleasure and pain, more
simple than these; as the pain of hunger and thirst, and the pleasure of eating and drinking to remove them: the
pain of teeth set on edge; the pleasure of music; pain from captious uninstructive wrangling, and the pleasure of
rational conversation with a friend, or of well-directed study in the search and discovery of truth. But the passions
being of much more concernment to us, I rather made choice to instance in them, and show how the ideas we have
of them are derived from sensation or reflection.
