596 MODERN METHODS OF SCIENCE. 
of his. He says: “In this examination of the physical man 
everything leads to the conclusion which we had already reached 
in our earlier lecture, and we can repeat with redoubled certainty 
that the differences among human groups are characters of race, 
and not of species. There exists only one human species, and 
consequently all men are brothers; all ought to be treated as 
such, whatever the origin, the blood, the color, the race ;” and in 
‘conclusion he further says: “ I shall not regret either my time or 
my pains, if I am able, in the name of science, and that alone, to 
render a little more clear and precise for you the great and sacred 
notion of the brotherhood of man.” 
One other example under this head, and I have done. The 
book of science teaches that the sun is the source of all light and 
heat; yet in that post-prophetic chapter of the book of our relig- 
ion it is said that the creation of the first day was light, and not 
until afterward was the sun created; and this was again a stum- 
bling-block to’ theologians, and many wished that Moses had been 
a little more particular. But science in its onward march, as it 
grouped together the matter floating in space to form in the be- 
ginning of time this earth (our circling globe), tells us that if we 
can imagine one to have been placed on our globe before it had 
consolidated, he would have seen vast seas of vapor floating 
around and far above it, shutting out the very light of heaven S0 
that darkness brooded over tbe waters; that the first benign 
influence that smiled upon the earth was the gentle rays of light 
struggling through the dark mist; and the prophetic eye, either 
on the plain, in the valley, or on the highest mountain ; 
would not behold whence it came, and might exclaim in sublime 
tic ecstasy: “God said, Let there be light; and there was 
en . 
light. é 
So I say, let our book of religion stand as it is; if it be not 
of God it will come to naught; and let science search for truth, 
and if it mistake its results it is certain to correct them in time; 
for the causes of its perturbations are as surely discovered as 
Leverrier and Adams discovered those of Uranus. 
Science and religion are both travelling towards the same great 
point — the Author of all truth— yet by two very different 
roads ; and if they be induced every now and then to turn off their
