ut how much of our study are we bound to give to
the processes by which those results are reached? The results have their
visible bearing on human life. But all the processes, too, all the items
of fact by which those results are reached and established, are
interesting. All knowledge is interesting to a wise man, and the
knowledge of nature is interesting to all men. It is very interesting
to know, that, from the albuminous white of the egg, the chick in the
egg gets the materials for its flesh, bones, blood, and feathers; while,
from the fatty yolk of the egg, it gets the heat and energy which enable
it at length to break its shell and begin the world. It is less
interesting, perhaps, but still it is interesting, to know that when a
taper burns, the wax is converted into carbonic acid and water.
Moreover, it is quite true that the habit of dealing with facts, which
is given by the study of nature, is, as the friends of physical science
praise it for being, an excellent discipline. The appeal, in the study
of nature, is constantly to observation and experiment; not only is it
said that the thing is so, but we can be made to see that it is so. Not
only does a man tell us that when a taper burns the wax is converted
into carbonic acid and water, as a man may tell us, if he likes, that
Charon is punting his ferry boat on the river Styx, or that Victor Hugo
is a sublime poet, or Mr. Gladstone the most admirable of statesmen; but
we are made to see that the conversion into carbonic acid and water does
actually happen. This reality of natural knowledge it is, which makes
the friends of physical science contrast it, as a knowledge of things,
with the humanist's knowledge, which is, they say, a knowledge of words.
And hence Professor Huxley is moved to lay it down that, "for the
purpose of attaining real culture, an exclusively scientific education
is at least as effectual as an exclusively literary education." And a
certain President of the Section for Mechanical Science in the British
Association is, in Scripture phrase, "very bold," and declares that if a
man, in his mental training, "has substituted literature and history for
natural science, he has chosen the less useful alternative." But whether
we go these lengths or not, we must all admit that in natural science
the habit gained of dealing with facts is a most valuable discipline,
and that every one should have some experience of it.

More than this, however, is demande
