The theory of population genetics and experiments on other organisms show that substantial changes can occur in the span of less than 100 generations, which for man reaches back to the time of the Roman Empire.
-
Because the brain can be guided by rational calculation only in a limited degree, it must fall back on the nuances of pleasure and pain mediated by the limbic system and other lower centers of the brain.

The fraction of Americans working in occupations concerned primarily with information has increased from 20 to nearly 50 percent of the work force.

The mosquito is an automaton. It can afford to be nothing else.
-
To search for unasked questions, plus questions to put to already acquired but unsought answers, it is vital to give full play to the imagination. That is the way to create truly original science.
-
We are compelled to drive toward total knowledge, right down to the levels of the neuron and the gene. When we have progressed enough to explain ourselves in these mechanistic terms...the result might be hard to accept.
-
Biological diversity is the key to the maintenance of the world as we know it... Eliminate one species, and another increases to take its place. Eliminate a great many species, and the local ecosystem starts to decay.
-
Of course, there is no reconciliation between the theory of evolution by natural selection and the traditional religious view of the origin of the human mind.
-
The history of life on earth has been a history of interaction between living things and their surroundings.
-
All my life I have placed great store in civility and good manners, practices I find scarce among the often hard-edged, badly socialized scientists with whom I associate. Tone of voice means a great deal to me in the course of debate. I despise the arrogance and doting self-regard so frequently found among the very bright.
-
Man's destiny is to know, if only because societies with knowledge culturally dominate societies that lack it. Luddites and anti-intellectuals do not master the differential equations of thermodynamics or the biochemical cures of illness. They stay in thatched huts and die young.
-
The closer the genetic relationship of the family members, as for example father-to-son, as opposed to uncle-to-nephew, the higher the degree of cooperation.
-
Humanity is part of nature, a species that evolved among other species. The more closely we identify ourselves with the rest of life, the more quickly we will be able to discover the sources of human sensibility and acquire the knowledge on which an enduring ethic, a sense of preferred direction, can be built.
-
God remains a viable hypothesis as the prime mover, however undefinable and untestable that conception may be.
-
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.
-
Be prepared mentally for some amount of chaos and failure. Waste and frustration often attend the earliest stages.
-
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.
-
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.
-
In 2010, my two Harvard mathematician colleagues and I dismantled kin-selection theory, which was the reigning theory of the origin of altruism at the time.
-
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.
-
We are not afraid of predators, we're transfixed by them, prone to weave stories and fables and chatter endlessly about them, because fascination creates preparedness, and preparedness, survival. In a deeply tribal way, we love our monsters.
-
I interpret contemporary human social behavior to comprise hypertrophic outgrowths of the simpler features of human nature joined together into an irregular mosaic.
-
Science is not marginal. Like art, it is a universal possession of humanity, and scientific knowledge has become a vital part of our species' repertory. It comprises what we know of the material world with reasonable certainty. . . . Thanks to science and technology, access to factual information of all kinds is rising exponentially.
-
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.
