Abstract perfection should always be the direction aimed at by human efforts, however imperfect they may be; and the success of sanitary legislation … - Robert Chambers

It has been among the visions of some dreaming philosophers that human life is capable of almost indefinite extension. The great Condorcet was one of these. He thought that by the removal of the two causes of evil—poverty and superfluity—by destroying prejudices and superstitions, and by various other operations, which he considered the purification of mankind, but which other people would call their pollution, the approach of death would by degrees be farther and farther indefinitely protracted. It is desirable that the practical views entertained by sanitary reformers should be kept widely distinct from any such theories, the character of which has been well drawn by Malthus when he says—"...Though I may not be able in the present instance to mark the limit at which further improvement will stop I can very easily mention a point at which it will not arrive."

The great men of antiquity—Cato, Brutus, Cassius, Antony, and Otho—forgot that they had obligations to their race as well as to themselves, when, in the selfish spirit of a pagan philosophy, they considered themselves entitled to put an end to their existence, and remove themselves from the world.

Thus we give, as is meet, a respectful reception to what is revealed through the medium of nature, at the same time that we fully reserve our reverence for all we have been accustomed to hold sacred, not one tittle of which it may ultimately be found necessary to alter.
