“I am always more interested in what I am about to do than what I have already done.”

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.

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.

The idea of the future, pregnant with an infinity of possibilities, is thus more fruitful than the future itself, and this is why we find more charm in hope than in possession, in dreams than in reality.

Christ has made of death a narrow starlit strip between the companionships of yesterday and the reunions of tomorrow.

I hope you’re brave enough to let go of a future that was never truly yours, that you never really wanted that was imposed upon you by dreams that were never really your own.

The future is not a gift: it is an achievement. Every generation helps make its own future. This is the essential challenge of the present.

My ideas for the future? To take over the world.

There are people in every time and every land who want to stop history in its tracks. They fear the future, mistrust the present, and invoke the security of the comfortable past which, in fact, never existed.

It is not enough to understand, or to see clearly. The future will be shaped in the arena of human activity, by those willing to commit their minds and their bodies to the task.

I’m really excited about my future plans, as I’m doing things differently and currently training like a Trojan in pursuit of becoming heavyweight champion of the world.
