"In most instances, affectionate relatives and kind friends would wish to prolong the existence of the individual who has reached that age; but if we look at the happiness of mankind in general, we shall find reason to believe that, like all the other general principles of nature, this one carries the impress of an all-wise and beneficent Creator; and that if man had it in his power to alter the arrangement, it may be questioned if he could improve it. At this age the great desires of life are generally accomplished, and the tired laborer in the hardest fields of exertion, which are those of the intellect, has had some years of quiet meditation on the long battle of life to which his days of energy and hope were devoted. The world has, in general, little more use for him; and should he—however meritorious his services, however honored his gray hairs—too long remain an actual living man, seeming to fill a part of the arena in which younger and abler combatants are looking for places, the consciousness of being honored and beloved may give way before the suspicion that he has become an encumbrance to the circle he once adorned."

“The facts, indeed, connected with this gloomy department of statistics show that the most valuable period of human life—that in which a man is producing more than he is consuming—is that which provides the greatest number of victims.”

“Indifference to life and indifference to the purity and amenity that sweeten existence must necessarily go together.”

“Seeing in our astral system many thousands of worlds in all stages of formation, from the most rudimental to that immediately preceding the present condition of those we deem perfect, it is unavoidable to conclude that all the perfect have gone through the various stages which we see in the rudimental. This leads us at once to the conclusion that the whole of our firmament was at one time a diffused mass of nebulous matter, extending through the space which it still occupies. So also, of course, must have been the other astral systems. Indeed, we must presume the whole to have been originally in one connected mass, the astral systems being only the first division into parts, and solar systems the second.”

“The elder Herschel, directing his wonderful tube towards the sides of our system, where stars are planted most rarely... was enabled with awe struck mind to see suspended in the vast empyrean astral systems, or, as he called them, firmaments, resembling our own. Like light cloudlets to a certain power of the telescope, they resolved themselves, under a greater power, into stars, though these generally seemed no larger than the finest particles of diamond dust. The general forms of these systems are various; but one at least has been detected as bearing a striking resemblance to the supposed form of our own. The distances are also various... The farthest observed by the astronomer were estimated by him as thirty-five thousand times more remote than Sirius, supposing its distance to be about twenty thousand millions of miles. It would thus appear, that not only does gravitation keep our earth in its place in the solar system, and the solar system in its place in our astral system, but it also may be presumed to have the mightier duty of preserving a local arrangement between that astral system and an immensity of others, through which the imagination is left to wander on and on without limit or stay, save that which is given by its inability to grasp the unbounded.”

“All, we see, is done by certain laws of matter, so that it becomes a question of extreme interest, what are such laws? All that can yet be said, in answer, is, that we see certain natural events proceeding in an invariable order under certain conditions, and thence infer the existence of some fundamental arrangement which, for the bringing about of these events, has a force and certainty of action similar to, but more precise and unerring than those arrangements which human society makes for its own benefit, and calls laws. It is remarkable of physical laws, that we see them operating on every kind of scale as to magnitude, with the same regularity and perseverance.”

“Ascending to the next group of rocks, we find the traces of life become more abundant, the number of species extended, and important additions made in certain vestiges of fuci, or sea plants, and of fishes. This group of rocks has been called by English geologists, the Silurian System, because largely developed at the surface of a district of western England, formerly occupied by a people whom the Roman historians call Silures.”
