O.M. Prejudices must be removed by OUTSIDE INFLUENCES or not at all.
Put that down.

Y.M. Very well; "Must be removed by outside influences or not at all."
Go on.

O.M. The iron's prejudice against ridding itself of the cumbering rock.
To make it more exact, the iron's absolute INDIFFERENCE as to whether the
rock be removed or not. Then comes the OUTSIDE INFLUENCE and grinds the
rock to powder and sets the ore free. The IRON in the ore is still
captive. An OUTSIDE INFLUENCE smelts it free of the clogging ore. The
iron is emancipated iron, now, but indifferent to further progress. An
OUTSIDE INFLUENCE beguiles it into the Bessemer furnace and refines it
into steel of the first quality. It is educated, now--its training is
complete. And it has reached its limit. By no possible process can it
be educated into GOLD. Will you set that down?

Y.M. Yes. "Everything has its limit--iron ore cannot be educated into
gold."

O.M. There are gold men, and tin men, and copper men, and leaden mean,
and steel men, and so on--and each has the limitations of his nature, his
heredities, his training, and his environment. You can build engines out
of each of these metals, and they will all perform, but you must not
require the weak ones to do equal work with the strong ones. In each
case, to get the best results, you must free the metal from its
obstructing prejudicial ones by education--smelting, refining, and so
forth.

Y.M. You have arrived at man, now?
