four times five is fourteen, and so on _ad libitum_. This is the way
that weird geometry proceeds: it sets before beginners certain strange
assumptions, and insists on their granting the existence of inconceivable
things, such as points having no parts, lines without breadth, and so on,
builds on these rotten foundations a superstructure equally rotten, and
pretends to go on to a demonstration which is true, though it starts from
premisses which are false.

Just so you, when you have granted the principles of any school, believe
in the deductions from them, and take their consistency, false as it is,
for a guarantee of truth. Then with some of you, hope travels through,
and you die before you have seen the truth and detected your deceivers,
while the rest, disillusioned too late, will not turn back for shame:
what, confess at their years that they have been abused with toys all
this time? so they hold on desperately, putting the best face upon it and
making all the converts they can, to have the consolation of good company
in their deception; they are well aware that to speak out is to sacrifice
the respect and superiority and honour they are accustomed to; so they
will not do it if it may be helped, knowing the height from which they
will fall to the common level. Just a few are found with the courage to
say they were deluded, and warn other aspirants. Meeting such a one, call
him a good man, a true and an honest; nay, call him philosopher, if you
will; to my mind, the name is his or no one's; the rest either have no
knowledge of the truth, though they think they have, or else have
knowledge and hide it, shamefaced cowards clinging to reputation.

But now for goodness' sake let us drop all this, cover it up with an
amnesty, and let it be as if it had not been said; let us, assume that
the Stoic philosophy, and no other, is correct; then we can examine
whether it is practicable and possible, or its disciples wasting their
