Life on Mars.
According to a report, the astronomers at Flagstaff, Ariz., now believe, after noting the change in colors of certain sections coincident with changes in the Martian year, that brownish sections of the planet which were before supposed to be seas were simply stretches of winter-denuded soil, since at other epochs these same sections show a blue-green tint, indicating fresh vegetation. If this is correct, the conclusion that intelligent beings inhabit that planet appears very reasonable.
From what we know of life in its various forms in the part of the universe we inhabit, plants exist for the sustenance of animal life, and the various animals are made to serve man in the conquest of nature and the progress of civilization; through which means alone, man can attain the perfection necessary to enable him to continue his existence in a still higher sphere. The entire creation, as far as we know it on earth, is one chain, in which each link is dependent on the other, and all interlocked with this final end in view. We have a right to conclude that the facts are similar in other worlds, especially to those belonging to our system, which constitute our nearest neighbors in space.
If, therefore, it is reasonably certain that vegetation flourishes on the planet Mars, it is equally certain that there is animal forms of life, and that there are intelligent beings, to rule over and to govern such existences for their own moral and intellectual development.
The logic of analogy forces this conclusion.

[If this argument makes sense, or perhaps especially if it doesn't, readers might profitably turn to Samuel Brown, “The Early Mormon Chain of Belonging,” Dialogue: A Journal of Mormon Thought 44, no 1 (Spring 2011): 1-52, or to a summary of the same ideas in Samuel Morris Brown, In Heaven as It Is On Earth: Joseph Smith and the Early Mormon Conquest of Death (Oxford University Press, 2012), p. 222, to understand this remnant of a very old way of viewing life, the universe, and everything, and its place in Mormon thought.]
