“Aryabhata conceived the earth as a rotating sphere in space, which causes the apparent rising and setting of the sun. Varahamihira disagreed and Brahmagupta derided Aryabhata — but unlike medieval Europe, the intellectual climate in India was free and tolerant of dissent.”

As quoted in The Discovery of Nature (1965), by Albert W. Bettex
Context: There are countless suns and countless earths all rotating round their suns in exactly the same way as the seven planets of our system. We see only the suns because they are the largest bodies and are luminous, but their planets remain invisible to us because they are smaller and non-luminous. The countless worlds in the universe are no worse and no less inhabited than our earth. For it is utterly unreasonable to suppose that those teeming worlds which are as magnificent as our own, perhaps more so, and which enjoy the fructifying rays of a sun just as we do, should be uninhabited and should not bear similar or even more perfect inhabitants than our earth. The unnumbered worlds in the universe are all similar in form and rank and subject to the same forces and the same laws. Impart to us the knowledge of the universality of terrestrial laws throughout all worlds and of the similarity of all substances in the cosmos! Destroy the theories that the earth is the center of the universe! Crush the supernatural powers said to animate the world, along with the so-called crystalline spheres! Open the door through which we can look out into the limitless, unified firmament composed of similar elements and show us that the other worlds float in an ethereal ocean like our own! Make it plain to us that the motions of all the worlds proceed from inner forces and teach us in the light of such attitudes to go forward with surer tread in the investigation and discovery of nature! Take comfort, the time will come when all men will see as I do.

The Canton, Ohio Speech, Anti-War Speech (1918)
Context: And now for all of us to do our duty! The clarion call is ringing in our ears and we cannot falter without being convicted of treason to ourselves and to our great cause.
Do not worry over the charge of treason to your masters, but be concerned about the treason that involves yourselves. Be true to yourself and you cannot be a traitor to any good cause on earth.
Yes, in good time we are going to sweep into power in this nation and throughout the world. We are going to destroy all enslaving and degrading capitalist institutions and re-create them as free and humanizing institutions. The world is daily changing before our eyes. The sun of capitalism is setting; the sun of socialism is rising. It is our duty to build the new nation and the free republic.

A Tritical Essay upon the Faculties of the Mind (1707)
Context: ALL Rivers go to the Sea, but none return from it. Xerxes wept when he beheld his Army, to consider that in less than a Hundred Years they would be all Dead. Anacreon was' Choakt with a Grape-stone, and violent Joy Kills as well as violent Grief. There is nothing in this World constant but Inconstancy; yet Plato thought that if Virtue would appear to the World in her own native Dress, all Men would be Enamoured with her. But now since Interest governs the World, and Men neglect the Golden Mean, Jupiter himself, if he came on the Earth would be Despised, unless it were as he did to Danae in a Golden Shower. For Men nowadays Worship the Rising Sun, and not the Setting.
