Revolution, revolution, and only revolution is our salvation.

The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.

Love is the only future God offers.

In all our journeying through space and time, it is, so far, the only world on which we know with certainty that the matter of the Cosmos has become alive and aware.

The only thing that will redeem mankind is cooperation.

The only game for us to play is creating the most extraordinary existence in the galaxy.

In creation alone there is the possibility of perfection.

Love is the only sane and satisfactory answer to the problem of human existence.

The only alternative to coexistence is codestruction.

The salvation of mankind lies only in making everything the concern of all

For men who lie on earth there is but one salvation, that their souls acknowledge and wing their way to Him by whom they have been made.

This is the only planet we know that supports life. We would do well to see the world as a sacred site that is holy, speak to our planet with kindness, and protect it as such.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet.
