“Conservation is a cause that has no end. There is no point at which we will say our work is finished.”

There is one quality that characterizes all of us who deal with the sciences of the earth and its life – we are never bored.

The aim of science is to discover and illuminate truth. And that, I take it, is the aim of literature, whether biography or history or fiction. It seems to me, then, that there can be no separate literature of science.

In every outthrust headland, in every curving beach, in every grain of sand there is the story of the earth.

Every mystery solved brings us to the threshold of a greater one.

Those who dwell, as scientists or laymen, among the beauties and mysteries of the earth, are never alone or weary of life.

The human race is challenged more than ever before to demonstrate our mastery, not over nature but of ourselves.

We cannot have peace among men whose hearts find delight in killing any living creature.

For mankind as a whole, a possession infinitely more valuable than individual life is our genetic heritage, our link with past and future… Yet genetic deterioration through man-made agents is the menace of our time.

Like the resource it seeks to protect, wildlife conservation must be dynamic, changing as conditions change, seeking always to become more effective.

We are not truly civilized if we concern ourselves only with the relation of man to man. What is important is the relation of man to all life.

But most of all I shall remember the monarchs, that unhurried westward drift of one small winged form after another, each drawn by some invisible force.

The Choice, after all, is ours to make.

It is ironic to think that man might determine his own future by something so seemingly trivial as the choice of an insect spray.

The control of nature is a phrase conceived in arrogance.

Wonder and humility are wholesome emotions and they do not exist side by side with a lust for destruction.

Knowing what I do, there would be no future peace for me if I kept silent.

Always end the name of your child with a vowel, so that when you yell the name will carry.

The traveler has to knock at every alien door to come to his own, and one has to wander through all the outer worlds to reach the innermost shrine at the end.

On the seashore of endless worlds children meet.

In terms of love, you’re not in control and I hate that feeling. I seem to write a lot of sad songs because I’m a very tragic person. But there’s always an element of humor at the end.

In short, the end justifies the means.

Woe to the statesman whose arguments for entering a war are not as convincing at its end as they were at the beginning, Bismarck had cautioned.

This is the end. For me the beginning of life.

The cross is not the terrible end to an otherwise godfearing and happy life, but it meets us at the beginning of our communion with Christ.
