The right course to follow lies between the two which have been
set out. The man who has done wrong to you is still a wrong-doer.
The question you have to consider is, What ought your conduct to be
towards a wrong-doer? Let there be no harbour given to any feeling
of personal revenge. But remember that it is your duty to disapprove
what is wrong, and that it is wisdom not too far to trust a man
who has proved himself unworthy to be trusted. I have no feeling of
selfish bitterness against the person who deceived me deliberately
and grossly, yet I cannot but judge that deliberate and gross
deceit is bad; and I cannot but judge that the person who deceived
me once might, if tempted, deceive me again: so he shall not have
the opportunity. I look at the horse which a friend offers me for
a short ride. I discern upon the knees of the animal a certain slight
but unmistakeable roughness of the hair. That horse has been down;
and if I mount that horse at all (which I shall not do except in
a case of necessity), I shall ride him with a tight rein, and with
a sharp look-out for rolling stones.

Another matter in regard to which Scylla and Charybdis are very
discernible, is the fashion in which human beings think and speak
of the good or bad qualities of their friends.

The primary tendency here is to blindness to the faults of a friend,
and over-estimate of his virtues and qualifications. Most people
are disposed extravagantly to over-value anything belonging to
or connected with themselves. A farmer tells you that there never
were such turnips as his turnips; a schoolboy thinks that the world
cannot show boys so clever as those with whom he is competing for
the first place in his class; a clever student at college tells
you what magnificent fellows are certain of his compeers--how sure
