Let us, I say, be agreed about the meaning of the terms we are using. I
talk of knowing the best which has been thought and uttered in the
world; Professor Huxley says this means knowing _literature_. Literature
is a large word; it may mean everything written with letters or printed
in a book. Euclid's _Elements_ and Newton's _Principia_ are thus
literature. All knowledge that reaches us through books is literature.
But by literature Professor Huxley means _belles lettres_. He means to
make me say, that knowing the best which has been thought and said by
the modern nations is knowing their _belles lettres_ and no more. And
this is no sufficient equipment, he argues, for a criticism of modern
life. But as I do not mean, by knowing ancient Rome, knowing merely more
or less of Latin _belles lettres_, and taking no account of Rome's
military, and political, and legal, and administrative work in the
world; and as, by knowing ancient Greece, I understand knowing her as
the giver of Greek art, and the guide to a free and right use of reason
and to scientific method, and the founder of our mathematics and physics
and astronomy and biology,--I understand knowing her as all this, and
not merely knowing certain Greek poems, and histories, and treatises,
and speeches,--so as to the knowledge of modern nations also. By knowing
modern nations, I mean not merely knowing their _belles lettres_, but
knowing also what has been done by such men as Copernicus, Galileo,
Newton, Darwin. "Our ancestors learned," says Professor Huxley, "that
the earth is the centre of the visible universe, and that man is the
cynosure of things terrestrial; and more especially was it inculcated
that the course of nature has no fixed order, but that it could be, and
constantly was, altered." But for us now, continues Professor Huxley,
"the notions of the beginning and the end of the world entertained by
our forefathers are no longer credible. It is very certain that the
earth is not the chief body in the material universe, and that the world
