The experience of climbing Kilimanjaro affected me so powerfully that, for a long time afterward, if I caught myself saying, "I'm not a person who likes to do that activity, eat that food, listen to that music," I would automatically go out and do what I imagined I didn't like. Generally I found I was wrong about myself - I liked what I thought I wouldn't like. And even if I didn't like the particular experience, I learned I liked having new experiences.
Exercise invigorates the body and sharpens the mind.
Each person bears a fear which is special to him. One man fears a close space and another man fears drowning; each laughs at the other and calls him stupid. Thus fear is only a preference, to be counted the same as the preference for one woman or another, or mutton for pig, or cabbage for onion.
A hundred years from now, people will look back on us and laugh. They'll say, 'You know what people used to believe? They believed in photons and electrons. Can you imagine anything so silly?' They'll have a good laugh, because by then there will be newer better fantasies... And meanwhile, you feel the way the boat moves? That's the sea. That's real. You smell the salt in the air? You feel the sunlight on your skin? That's all real. Life is wonderful. It's a gift to be alive, to see the sun and breathe the air. And there isn't really anything else.
We cause our diseases. We are directly responsible for any illness that happens to us.
False fears are a plague, a modern plague!
All your life people will tell you things. And most of the time, probably ninety-five percent of the time, what they'll tell you will be wrong.
Nobody dares to solve the problems-because the solution might contradict your philosophy, and for most people clinging to beliefs is more important than succeeding in the world.
When you have a strongly held belief, don't you think it's important to express that belief accurately?
You know, at times like this one feels, well, perhaps extinct animals should be left extinct.
Harassment is about power---the undue exercise of power by a superior over a subordinate.
In a media-saturated world, persistent hype lends unwarranted credulity to the wildest claims.
The work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.
Face the facts, all these environmental organizations are thirty, forty, fifty years old. They have big buildings, big obligations, big staffs. They may trade on their youthful dreams, but the truth is, they're now part of the establishment. And the establishment works to preserve the status quo. It just does.
Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled.
To apply general tools to specific problems is to fail.
Welcome...to Jurassic Park!
We think we know what we are doing. We have always thought so.
The purpose of history is to explain the present - to say why the world around us is the way it is. History tells us what is important in our world, and how it came to be. It tells us what is to be ignored, or discarded. That is true power - profound power. The power to define a whole society.
Environmentalism needs to be absolutely based in objective and verifiable science, it needs to be rational, and it needs to be flexible. And it needs to be apolitical. To mix environmental concerns with the frantic fantasies that people have about one political party or another is to miss the cold truth - that there is very little difference between the parties, except a difference in pandering rhetoric.
All human behavior has a reason. All behavior is solving a problem.
In order not to be misunderstood, I want it perfectly clear that I believe it is incumbent on us to conduct our lives in a way that takes into account all the consequences of our actions, including the consequences to other people, and the consequences to the environment.
All major changes are like death. You can't see to the other side until you are there.
Let's be clear. The planet is not in jeopardy. We are in jeopardy. We haven't got the power to destroy the planet - or to save it. But we might have the power to save ourselves.
The past history of human belief is a cautionary tale. We have killed thousands of our fellow human beings because we believed they had signed a contract with the devil, and had become witches. We still kill more than a thousand people each year for witchcraft. In my view, there is only one hope for humankind to emerge from what Carl Sagan called "the demon-haunted world" of our past. That hope is science.
