ASSOCIATION BY SIMILARITY AND CONTRAST.--All are familiar with the fact
that like tends to suggest like. One friend reminds us of another friend
when he manifests similar traits of character, shows the same tricks of
manner, or has the same peculiarities of speech or gesture. The telling
of a ghost or burglar story in a company will at once suggest a similar
story to every person of the group, and before we know it the
conversation has settled down to ghosts or burglars. One boastful boy is
enough to start the gang to recounting their real or imaginary exploits.
Good and beautiful thoughts tend to call up other good and beautiful
thoughts, while evil thoughts are likely to produce after their own
kind; like produces like.
