ogram, all except the victory in
the battle fields.

This war was a calamity of unprecedented magnitude for the world and it is
our duty to study it dispassionately and learn the lesson of it, if we do
not want to be moral accomplices of this great modern crime, by letting
the world drift into an even worse catastrophe. We have to arouse
ourselves from our inertia and go to the bottom of this problem and
analyse it ruthlessly, no matter whether the analysis be pleasant or not.
We must value everyone of our "ten sacred dead" at least as much as we
value one rabbit killed in scientific laboratories, and take the lesson to
heart or be prepared for a repetition of world slaughter.

If Human Engineering had been established long ago our social system would
have been different, our civilization would have been much higher, this
war would have been avoided. We do not need to delude ourselves. The World
War was the result of badly balanced social and economic forces. The world
needs other "balances of power" than such as are devised by lawyers and
politicians, by single-selfish or group-selfish interests. Humanity is
reaching out for a science and art of human guidance based upon a right
understanding of human nature.

Chapter IX. Manhood Of Humanity

In a previous chapter I have said that the World War marks the end of one
vast period in the life of humankind and marks the beginning of another.
It marks the end of Humanity's Childhood and the beginning of Humanity's
Manhood.

Our human Past is a mighty fact of our world. Many facts are unstable,
impermanent, and evanescent--they are here to-day, and to-morrow they are
gone. Not so with the great fact of our human Past. Our past abides.

"It is permanent. It can be counted on. It is nearly eternal as
the race of man. Out of that past we have come. Into it we are
constantly returning. Meanwhile, it is of the utmost importance to
our lives. It contains the _roots_ of all we are, and of all we
have of wisdom, of science, of philosophy, of art, of
jurisprudence, of customs and institutions. It contains the record
or ruins of all the experiments that man has made during a quarter
or a half million years in the art of living in this world."
(Keyser, _Human Worth of Rigorous Thinking_.)

In our relation to the past there are three wide-open ways in which one
may be a fool. One of the ways is the way of ignoring the past--the way o
