part 4

XII. CO-OPERATION will teach you the value of
team-work in all you do. In this lesson you
will be taught how to apply the law of the
"Master Mind" described in this Introduction
and in Lesson Two of this course. This lesson
will show you how to co-ordinate your own
efforts with those of others, in such a manner
that friction, jealousy, strife, envy and
cupidity will be eliminated. You will learn
how to make use of all that other people have
learned about the work in which you are
engaged.
XIII. PROFITING BY FAILURE will teach you
how to make stepping stones out of all of
your past and future mistakes and failures. It
will teach you the difference between
"failure" and "temporary defeat," a difference
which is very great and very important. It
will teach you how to profit by your own
failures and by the failures of other people.
XIV. TOLERANCE will teach you how to avoid
the disastrous effects of racial and religious
prejudices which mean defeat for millions of
people who permit themselves to become
entangled in foolish argument over these
subjects, thereby poisoning their own minds
and closing the door to reason and
investigation. This lesson is the twin sister of
the one on ACCURATE THOUGHT, for the
reason that no one may become an Accurate
Thinker without practicing tolerance.
Intolerance closes the book of Knowledge
and writes on the cover, "Finis! I have

  learned it all!" Intolerance makes enemies of
  those who should be friends. It destroys
  opportunity and fills the mind with doubt,
  mistrust and prejudice.
