Here we are, the most clever species ever to have lived. So how is it we can destroy the only planet we have?
Only those within whose own consciousness the sun rise and set, the leaves burgeon and wither, can be said to be aware of what living is.
Both the cockroach and the bird would get along very well without us, although the cockroach would miss us most.
Roy Walker: Next was the English naturalist: Charles Darwin. He loved all living things. Creatures, plants... everything alive.
Raven Darkholme: Darwin's dead, Charles, and we can't even bury him. Erik Lehnsherr: We can avenge him!
The eggers destroy all the eggs that are sat upon, to force the birds to lay fresh eggs, and by robbing them regularly compel them to lay until nature is exhausted, and so but few young ones are raised.
One learns more from listening than speaking. And both the wind and the people who continue to live close to nature still have much to tell us which we cannot hear within university walls.
What we must understand is that the industries, processes, and inventions created by modern science can be used either to subjugate or liberate. The choice is up to us.
When I began in 1960, individuality wasn't an accepted thing to look for; it was about species-specific behaviour. But animal behaviour is not hard science. There's room for intuition.
This is a global fight to get the right people in the right place and we're talking about people with PhDs in engineering, computer science, mathematics.
As I have tried to show, science, in producing the airplane and the wireless, has created a new international political environment to which governments must adjust their foreign policies.
Science is the one culture that's truly global - protons, proteins and Pythagoras's Theorem are the same from China to Peru. It should transcend all barriers of nationality. It should straddle all faiths, too.
It's often better to read first-rate science fiction than second-rate science - it's far more stimulating, and perhaps no more likely to be wrong.
Science is a part of culture. Indeed, it is the only truly global culture because protons and proteins are the same all over the world, and it's the one culture we can all share.
We can trace things back to the earlier stages of the Big Bang, but we still don't know what banged and why it banged. That's a challenge for 21st-century science.
There is an ever-widening gap between what science allows and what we should actually do. There are many doors science can open that should be kept closed, on prudential or ethical grounds.
In the past, it was only in science fiction novels that you could read about ordinary people being able to go to space... But you laid the foundation for space tourism.
As a citizen, as a public scientist, I can tell you that Einstein essentially overturned a so strongly established paradigm of science, whereas Darwin didn't really overturn a science paradigm.
Science has revealed that the human body is made up of millions and millions of atoms... For example, I am made up of 5.8x10 27 atoms.
Science is global. Einstein's equation, E=mc2, has to reach everywhere. Science is a beautiful gift to humanity, we should not distort it. Science does not differentiate between multiple races.
Evolution seems to close the heart to some of the plainest spiritual truths while it opens the mind to the wildest guesses advanced in the name of science.
