SCIENCE AND ENGINEERING 459
professional engineers; it ought rather to give them a
feeling of humility. For consider its spirit and its scope.
Its spirit is not a self-serving spirit nor a class-serving
spirit nor any provincial spirit; it is a world-serving
spirit-the spirit of devotion to the well-being of all
mankind including posterity.
And what is its scope? Is it confined to the kinds
of work done today by professional engineers in the name
of engineering? It is by no means thus confined; its
scope is immeasurably greater; for, over and above such
work, which no one could wish to belittle, it embraces
whatever may be intelligent, humane, and magnanimous
in the promotion of science, in the work of educational
leadership, in the conduct of industrial life, in the establishment and administration of justice-in all the affairs
of a statesmanship big enough to embrace the world.
I am facing the future, and I say "in all the affairs
of statesmanship" because I do not doubt that the affairs
of state,-which are the affairs of man,-will at length
be rescued from the hands of "politicians" and be committed to a statesmanship which will be an engineering
statesmanship because it will guide itself and the affairs
of state in scientific light by scientific means.
Engineering statesmanship will know enough to know
that scientific knowledge cannot be applied to the conduct
of human affairs if such knowledge does not exist; it will
have sense enough to know also that knowledge which
does not exist cannot be suddenly called into existence at
the moments when it is needed. Engineering statesmanship will, therefore, be sagacious enough to make ample
provision in advance for scientific research; not only for
technological research, but,-primarily and especially,for that kind of research which does not consciously aim
