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

I demonstrate by means of philosophy that the earth is round, and is inhabited on all sides; that it is insignificantly small, and is borne through the stars.

First of all, we must note that the universe is spherical.

Man, a mere inhabitant of the earth, cannot overstep its boundaries! But though he is confined to its crust, he may penetrate into all its secrets.

As the earth spins through space, a view from above the North Pole would encompass most of the wealth of the world - most of its food, productive machines, doctors, engineers and teachers. A view from the opposite pole would encompass most of the world's poor.

Even in our day, science suspects beyond the Polar seas, at the very circle of the Arctic Pole, the existence of a sea which never freezes and a continent which is ever green.

It is well that the earth is round that we do not see too far ahead.

I seemed to vow to myself that some day I would go to the region of ice and snow and go on and on till I came to one of the poles of the earth, the end of the axis upon which this great round ball turns.

The wideness of the horizon has to be inside us, cannot be anywhere but inside us, otherwise what we speak about is geographic distances.

You know, if you hang around this earth long enough you really see how things come full circle.
