The channels of human mental development... are circuitous and variable. Rather than specify a single trait, human genes prescribe the capacity to develop a certain array of traits.
-
Consider the nematode roundworm, the most abundant of all animals. Four out of five animals on Earth are nematode worms — if all solid materials except nematode worms were to be eliminated, you could still see the ghostly outline of most of it in nematode worms.
-
The extinctions ongoing worldwide promise to be at least as great as the mass extinction that occurred at the end of the age of dinosaurs.
-
Common sense is merely unaided intuition, and unaided intuition is reasoning performed in the absense of instruments and the tested knowledge of science. Common sense tells us that massive satellites cannot hang suspended 36,000 kilometers above the one point on the earth's surface, but they do.
-
The history of life on earth has been a history of interaction between living things and their surroundings.
-
Progress, then, is a property of the evolution of life as a whole by almost any conceivable intuitive standard.... let us not pretend to deny in our philosophy what we know in our hearts to be true.

It was inspiring to learn of the new Bachelor of Environmental Studies Program, and I congratulate you for it. Singapore is geographically in the right central position for an influence in Asia and Australia, and NUS has the reputation and academic strength to make it effective.
-
If enough species are extinguished, will the ecosystems collapse, and will the extinction of most other species follow soon afterward? The only answer anyone can give is: possibly. By the time we find out, however, it might be too late. One planet, one experiment.

There is no such thing as a typically 'schizophrenogenic' (schizophrenia-producing) family arrangement, one most likely to produce a mentally ill adult from a child with the potential for the disease.
-
The search for knowledge is in our genes. It was put there by our distant ancestors who spread across the world, and it's never going to be quenched.
-
Humanity, in the desperate attempt to fit 8 billion or more people on the planet and give them a higher standard of living, is at risk of pushing the rest of life off the globe.
-
The only other mammalian carnivores that take outsized prey are lions, hyenas, wolves, and African wild dogs. Each... has an exceptionally advanced social life, prominently featuring the pursuit of prey in coordinated packs.
-
The incest taboo is another major category of primed learning.
-
Darwin's dice have rolled badly for Earth. The human species is, in a word, an environmental abnormality. Perhaps a law of evolution is that intelligence usually extinguishes itself.
-
Evolution by natural selection is not an idle hypothesis. The genetic variation on which selection acts is well understood in principle all the way down to the molecular level.
-
The most dangerous of devotions, in my opinion, is the one endemic to Christianity: I was not born to be of this world. With a second life waiting, suffering can be endured- especially in other people. The natural environment can be used up. Enemies of the faith can be savaged and suicidal martyrdom praised.
-
Are human beings innately aggressive? ...The answer to it is yes. ...Only by redefining the words 'innateness' and 'aggression' to the point of uselessness might we correctly say that human aggressiveness is not innate.
-
This is the assembly of life that took a billion years to evolve. It has eaten the storms - folded them into its genes - and created the world that created us. It holds the world steady.
-
To be anthropocentric is to remain unaware of the limits of human nature, the significance of biological processes underlying human behavior, and the deeper meaning of long-term genetic evolution.
-
In the attempt to make scientific discoveries, every problem is an opportunity — and the more difficult the problem, the greater will be the importance of its solution.
-
Self-knowledge will reveal the elements of biological human nature from which modern social life proliferated in all its strange forms.
-
Nature first, then theory. Or, better, Nature and theory closely intertwined while you throw all your intellectual capital at the subject. Love the organisms for themselves first, then strain for general explanations, and, with good fortune, discoveries will follow. If they don't, the love and the pleasure will have been enough.
-
In science, you really do need to have a purpose-driven life. You will succeed to the extent that you get the most out of your career so that you can give the most back. Try to be an addict, driven to achieve discoveries, learning new things, and then writing about them.

Hands-on experience at the critical time, not systematic knowledge, is what counts in the making of a naturalist. Better to be an untutored savage for a while, not to know the names or anatomical detail. Better to spend stretches of time just searching and dreaming.
