themselves worked in some other field and have an imperfect
acquaintance with the particular field that they happen to be praising.
The metaphysician finds the reasonings of the "First Principles" rather
loose and inconclusive; the biologist pays little heed to the
"Principles of Biology"; the sociologist finds Spencer not particularly
accurate or careful in the field of his predilection. He has tried to
be a professor of all the sciences, and it is too late in the world's
history for him or for any man to cope with such a task. In the days
of Plato a man might have hoped to accomplish it.

6. WHAT PHILOSOPHY MEANS IN OUR TIME.--It savors of temerity to write
down such a title as that which heads the present section. There are
men living to-day to whom philosophy means little else than the
doctrine of Kant, or of Hegel, or of the brothers Caird, or of Herbert
Spencer, or even of St. Thomas Aquinas, for we must not forget that
many of the seminaries of learning in Europe and some in America still
hold to the mediaeval church philosophy.

But let me gather up in a few words the purport of what has been said
above. Philosophy once meant the whole body of scientific knowledge.
Afterward it came to mean the whole body of knowledge which could be
attained by the mere light of human reason, unaided by revelation. The

which somehow concerns itself with the whole system of things, rather
than with any limited division of that broad field. It is a notion not
peculiar to the disciples of Spencer. There are many to whom
philosophy is a "_Weltweisheit_," a world-wisdom. Shall we say that
