The earth is the Lord's fullness thereof: this is no longer a hollow dictum of religion, but a directive for economic action toward human brotherhood.
Lewis Mumford

Land: A part of the earth's surface, considered as property. The theory that land is property subject to private ownership and control is the foundation of modern society, and is eminently worthy of the superstructure.
Ambrose Bierce

Atlas was permitted the opinion that he was at liberty, if he wished, to drop the Earth and creep away; but this opinion was all that he was permitted.
Franz Kafka

In times of change learners inherit the earth; while the learned find themselves beautifully equipped to deal with a world that no longer exists.
Eric Hoffer

There is nothing on this earth more to be prized than true friendship.
Thomas Aquinas

The atom bombs are piling up in the factories, the police are prowling through the cities, the lies are streaming from the loudspeakers, but the earth is still going round the sun.
George Orwell

Today the theory of evolution is about as much open to doubt as the theory that the earth goes round the sun.
Richard Dawkins

There is no such thing on earth as an uninteresting subject; the only thing that can exist is an uninterested person.
Gilbert K. Chesterton

The true object of all human life is play. Earth is a task garden; heaven is a playground.
Gilbert K. Chesterton

The earth also is spherical, since it presses upon its center from every direction.
Nicolaus Copernicus

I can easily conceive, most Holy Father, that as soon as some people learn that in this book which I have written concerning the revolutions of the heavenly bodies, I ascribe certain motions to the Earth, they will cry out at once that I and my theory should be rejected.
Nicolaus Copernicus

Accordingly, since nothing prevents the earth from moving, I suggest that we should now consider also whether several motions suit it, so that it can be regarded as one of the planets. For, it is not the center of all the revolutions.
Nicolaus Copernicus

Therefore, in the course of the work I have followed this plan: I describe in the first book all the positions of the orbits together with the movements which I ascribe to the Earth, in order that this book might contain, as it were, the general scheme of the universe.
Nicolaus Copernicus

Those who know that the consensus of many centuries has sanctioned the conception that the earth remains at rest in the middle of the heavens as its center, would, I reflected, regard it as an insane pronouncement if I made the opposite assertion that the earth moves.
Nicolaus Copernicus

Moreover, since the sun remains stationary, whatever appears as a motion of the sun is really due rather to the motion of the earth.
Nicolaus Copernicus

Therefore, having obtained the opportunity from these sources, I too began to consider the mobility of the earth.
Nicolaus Copernicus

The earth together with its surrounding waters must in fact have such a shape as its shadow reveals, for it eclipses the moon with the arc of a perfect circle.
Nicolaus Copernicus

We regard it as a certainty that the earth, enclosed between poles, is bounded by a spherical surface.
Nicolaus Copernicus

Yet if anyone believes that the earth rotates, surely he will hold that its motion is natural, not violent.
Nicolaus Copernicus

The massive bulk of the earth does indeed shrink to insignificance in comparison with the size of the heavens.
Nicolaus Copernicus
