“By suggestion and example, I believe children can be helped to hear the many voices about them. Take Time to listen and talk about the voices of the earth and what they mean-the majestic voice of thunder, the winds, the sound of surf or flowing streams.”

For all at last return to the sea- to Oceanus, the ocean river, like the ever-flowing stream of time, the beginning and the end.

The lasting pleasures of contact with the natural world are not reserved for scientists but are available to anyone who will place himself under the influence of earth, sea and sky and their amazing life.

I sincerely believe that for the child, and for the parent seeking to guide him, it is not half so important to ‘know’ as to ‘feel’.

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.

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.

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.

A man who believes in freedom will do anything under the sun to acquire, or preserve his freedom.

I once believed love would be burning red.

I believe in being strong when everything seems to be going wrong.

It is hard to fail but it is worse never to have tried to succeed.

If you hire people just because they can do a job, they’ll work for your money. But if you hire people who believe what you believe, they’ll work for you with blood and sweat and tears.

Say what you have to say, not what you ought. Any truth is better than make-believe.
