Discover'd that my love is worth esteem,
I ask no more—but let us hence together,
And I — let me say we”

"The First and the Last Catastrophe" in Popular Science Monthly (Vol. 7, (July 1875)
Context: It is a very serious thing to consider that not only the earth itself and all that beautiful face of Nature we see, but also the living things upon it, and all the consciousness of men, and the ideas of society, which have grown up upon the surface, must come to an end. We who hold that belief must just face the fact and make the best of it; and I think we are helped in this by the words of that Jew philosopher who was himself a worthy crown to the splendid achievements of his race in the cause of progress during the middle ages, Benedict Spinoza. He said, "The freeman thinks of nothing so little as of death, and his contemplation is not of death but of life." Our interest, it seems to me, lies with so much of the past as may serve to guide our actions in the present, and to intensify our pious allegiance to the fathers who have gone before us, and the brethren who are with us; and our interest lies with so much of the future as we may hope will be appreciably affected by our good actions now. Beyond that, as it seems to me, we do not know, and we ought not to care. Do I seem to say, "Let us eat and drink, for to-morrow we die?" Far from it; on the contrary, I say, "Let us take hands and help, for this day we are alive together."

Context: Think not so much of what thou hast not as of what thou hast: but of the things which thou hast, select the best, and then reflect how eagerly they would have been sought, if thou hadst them not. At the same time, however, take care that thou dost not, through being so pleased with them, accustom thyself to overvalue them, so as to be disturbed if ever thou shouldst not have them.
