We started the AIDS virus. We are only able to maintain our level of living by making sure that Third World people live in grinding poverty.
The truly privileged theories are not the ones referring to any particular scale of size or complexity, nor the ones situated at any particular level of the predictive hierarchy, but the ones that contain the deepest explanations.
I know one lab that studies nicotine receptors and all the scientists are smokers, and another lab that studies impulse control and they're all overweight.
My father and mother treated us children as intellectual equals, thus greatly bolstering our self-confidence and our interest in ideas of all kinds.
Some wonder whether some day we will arrive at a theory of everything and run out of new problems to solve - much as the effort to explore the earth ran out of new continents to explore.
In order to achieve a true understanding of string theory, some new idea will be required, and most likely, some break with the concepts on which we've traditionally based physical theory.
During my solitude, conflicting thoughts increased; but much exercise of soul had the effect of causing the scriptures to gain complete ascendancy over me.
I add, that those who are bent on restoring the whole church ought to be well instructed in the word, and to abstain from doing anything under the pretext of simplicity.
I am a person who sings. I know not everyone is, but that won't keep the Spirit from putting a song in your heart.
I think we're still in a muddle with our language, because once you get words and a spoken language it gets harder to communicate.
When you meet chimps you meet individual personalities. When a baby chimp looks at you it's just like a human baby. We have a responsibility to them.
Most Africans don't get to see these wild animals at all. Once they see and learn about them, they are much more likely to become involved in protecting the environment.
On the day-long follows that I used to do with mothers and their offspring - these chimp families that I knew so well - there was hardly a day when I didn't learn something new about them.
People say maybe we have a soul and chimpanzees don't. I feel that it's quite possible that if we have souls, chimpanzees have souls as well.
When I was two, a dragonfly flew near me. A man knocked it to the ground and trod on it. I remember crying because I'd caused the dragonfly to be killed.
I learned from my dog long before I went to Gombe that we weren't the only beings with personalities. What the chimps did was help me to persuade others.
Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.
What makes tar sands particularly odious is that the energy you get out in the end, per unit carbon dioxide, is poor. It's equivalent to burning coal in your automobile.
If your child gets asthma, the fossil fuel industry doesn't pay. Or if there's a natural disaster, the bill is paid by the taxpayer, not the fossil fuel company.
Coal is responsible for as much atmospheric carbon dioxide as other fossil fuels combined and it still has far greater reserves. We must stop using it.
A famous name has this peculiarity that it becomes gradually smaller especially in natural sciences where each succeeding discovery invariably overshadows what precedes.
