well as among ideas; though with this remarkable difference, that
ideas are associated by resemblance, contiguity, and causation; and
impressions only by resemblance.

In the THIRD place, it is observable of these two kinds of association,
that they very much assist and forward each other, and that the
transition is more easily made where they both concur in the same
object. Thus a man, who, by any injury from another, is very much
discomposed and ruffled in his temper, is apt to find a hundred subjects
of discontent, impatience, fear, and other uneasy passions; especially
if he can discover these subjects in or near the person, who was
the cause of his first passion. Those principles, which forward the
transition of ideas, here concur with those, which operate on the
passions; and both uniting in one action, bestow on the mind a double
impulse. The new passion, therefore, must arise with so much greater
violence, and the transition to it must be rendered so much more easy
and natural.

Upon this occasion I may cite the authority of an elegant writer, who
expresses himself in the following manner.

"As the fancy delights in every thing that is great, strange, or
beautiful, and is still more pleased the more it finds of these
perfections in the same object, so it is capable of receiving a new
satisfaction by the assistance of another sense. Thus any continued
sound, as the music of birds, or a fall of waters, awakens every moment
the mind of the beholder, and makes him more attentive to the several
beauties of the place, that lie before him. Thus if there arises a
fragrancy of smells or perfumes, they heighten the pleasure of the
imagination, and make even the colours and verdure of the landschape
appear more agreeable; for the ideas of both senses recommend each
other, and are pleasanter together than when they enter the mind
separately: As the different colours of a picture, when they are well
disposed, set off one another, and receive an additional beauty from the
advantage of the situation." [Addison, SPECTATOR 412, final paragraph.]

In this phaenomenon we may remark the association both of impressions
and ideas, as well as the mutual assistance they lend each other.

SECT. V OF THE INFLUENCE OF THESE RELATIONS ON PRIDE AND HUMILITY

These principles being established on unquestionable experience, I begin
to consider how we shall apply them, by revolving over all the causes of
pride and humility, whet
