porting this broad view of the subject, and illustrating the greatness
and the goodness of the cause of African colonization.
  The unity of the human race must be considered a fundamental and
an accepted truth. Every department of knowledge has been search-
ed for evidence, and all respond with a uniform testimony. The phys-
ical structure, constitution, and habits of the race- the mode in which
it is produced, in which it exists, in which it perishes-every thing
that touches its mere animal existence, demonstrates the absolute cer-
tainty of its unity-so that no other generalization of physiology is
more clear and more sure. Rising one step, to the highest manifesta-
tion of man's physical organization-his use of language and the pow-
er of connected speech-the most profound survey of this most com-
plex and tedious part of knowledge, conducts the enquirer to no con-
clusion more indubitable than that there is a common origin, a com-
mon organization, a common nature, underlying and running through
this endless variety of a common power, peculiar to the race and to
it alone. Thus a second science-philology-has borne its marvelous
testimony. Rising one more step, and passing more completely into
a higher region, we find the rational and moral nature of men of eve-
ry age and kindred, absolutely the same. Those great faculties by
which man alone-and yet by which every man-perceives that there
is in things that distinction which we call true and false, and that oth-
er distinction which we call good and evil; upon which distinctions
and which faculties rests at last the moral and the intellectual destiny
of the entire race; belonging to us as men, without which we are not
men, with which we are the head of the visible creation of God. So
has a third science-the science which treats of the whole moral con-
stitution of man, embracing in its wide scope many subordinate sci-
ences-delivered its testimony. If we rise another step, and survey
man as he is gathered into families, and tribes, and nations, with an
endless variety of development, we still behold the broad foundations
of a common nature reposing under all-the living proofs of a com-
mon origin struggling through all-the grand principles of a common
being ruling in the midst of all. So a fourth, and the youngest of
the sciences-ethnology-brings her tribute. And now, from this
lofty summit survey the whole track of ages. In their length and in
their breadth, scrutinize the recorded annals of mankind. There is
not one page on which one fact is written-which favors the historical
idea of a diversity of nature or origin-while the whole scope of hu-
man story involves, assumes, and proclaims, as the first and grandest
historic truth, the absolute unity of the race. And then, mounting
from earth to heaven, ask God-the God of truth-and He will tell
you, that the foundation truth of all his work of creation and of prov-
idence, is the sublime certainty that our race was created, in his own
