intelligence better than do the greater number of adult eyes. David
Garrick's were evidently unpreoccupied, like theirs. The look of
intelligence is outward--frankly directed upon external things; it is
observant, and therefore mobile without inner restlessness. For restless
eyes are the least observant of all--they move by a kind of distraction.
The looks of observant eyes, moving with the living things they keep in
sight, have many pauses as well as flights. This is the action of
intelligence, whereas the eyes of intellect are detained or darkened.

Rational perception, with all its phases of humour, are best expressed by
a child, who has few second thoughts to divide the image of his momentary
feeling. His simplicity adds much to the manifestation of his
intelligence. The child is the last and lowest of rational creatures,
for in him the "rational soul" closes its long downward flight with the
bright final revelation.

He has also the chief beauty of the irrational soul of the mind, that is,
of the lower animal--which is singleness. The simplicity, the integrity,
the one thing at a time, of a good animal's eyes is a great beauty, and
is apt to cause us to exaggerate our sense of their expressiveness. An
animal's eyes, at their best, are very slightly expressive; languor or
alertness, the quick expectation, even the aloofness of doubt they are
able to show, but the showing is mechanical; the human sentiment of the
spectator adds the rest.

All this simplicity the child has, at moments, with the divisions and
delicacies of the rational soul, also. His looks express the first, the
last, and the clearest humanity. He is the first by his youth and the
last by his lowliness. He is the beginning and the result of the
creation of man.
