Love is life's end, but never ending. Love is life's wealth, never spent, but ever spending. Love's life's reward, rewarded in rewarding. - Herbert Spencer

Consumptive patients, with lungs incompetent to perform the duties of lungs, people with defective hearts that break down under excitement of the circulation, people with any constitutional flaw preventing the due fulfillment of the conditions of life are continually dying out and leaving behind those fit for the climate, food, and habits to which they are born....And thus is the race kept free from vitiation.

The saying that beauty is but skin deep is but a skin-deep saying.

The current opinion that science and poetry are opposed is a delusion. ... Think you that a drop of water, which to the vulgar eye is but a drop of water, loses any thing in the eye of the physicist who knows that its elements are held together by a force which, if suddenly liberated, would produce a flash of lightning? Think you that what is carelessly looked upon by the uninitiated as a mere snow-flake does not suggest higher associations to one who has seen through a microscope the wondrously varied and elegant forms of snow-crystals? Think you that the rounded rock marked with parallel scratches calls up as much poetry in an ignorant mind as in the mind of a geologist, who knows that over this rock a glacier slid a million years ago? The truth is, that those who have never entered upon scientific pursuits know not a tithe of the poetry by which they are surrounded.
