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

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

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
