as soon be
quietly chipping my own flint axe, after the manner of my forefathers
a few thousand years back, as be troubled with the endless malady of
thought which now infests us all, for such reward. But I venture to
say that such views are contrary alike to reason and to fact. Those who
discourse in such fashion seem to me to be so intent upon trying to see
what is above Nature, or what is behind her, that they are blind to what
stares them in the face, in her.
I should not venture to speak thus strongly if my justification were not
to be found in the simplest and most obvious facts,--if it needed more
than an appeal to the most notorious truths to justify my assertion,
that the improvement of natural knowledge, whatever direction it has
taken, and however low the aims of those who may have commenced it--has
not only conferred practical benefits on men, but, in so doing, has
effected a revolution in their conceptions of the universe and of
themselves, and has profoundly altered their modes of thinking and
their views of right and wrong. I say that natural knowledge, seeking
to satisfy natural wants, has found the ideas which can alone still
spiritual cravings. I way that natural knowledge, in desiring to
ascertain the laws of comfort, has been driven to discover those of
conduct, and to lay the foundations of a new morality.
Let us take these points separately; and, first, what great ideas has
natural knowledge introduced into men's minds?
I cannot but think that the foundations of all natural knowledge were
laid when the reason of man first came face to face with the facts of
Nature; when the savage first learned that the fingers of one hand are
fewer than those of both; that it is shorter to cross a stream than to
head it; that a stone stops where it is unless it be moved, and that it
drops from the hand which lets it go; that light and heat come and go
with the sun; that sticks burn away to a fire; that plants and animals
grow and die; that if he struck his fellow-savage a blow he would make
him angry, and perhaps get a blow in return, while if he offered him a
fruit he would please him, and perhaps receive a fish in exchange. When
men had acquired this much knowledge, the outlines, rude though they
were, of mathematics, of physics, of chemistry, of biology, of moral,
economical, and political science, were sketched. Nor did the germ of
religion fail when science began to bud. Listen to words which though
