In the process of natural selection, then, any device that can insert a higher proportion of certain genes into subsequent generations will come to characterize the species.
This planet can be a paradise in the 22nd century.
We need freedom to roam across land owned by no one but protected by all, whose unchanging horizon is the same that bounded the world of our millennial ancestors.
Search until you find a passion and go all out to excel in its expression.
The love of complexity without reductionism makes art; the love of complexity with reductionism makes science.
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.
I believe that traditional religious belief and scientific knowledge depict the universe in radically different ways. At the bedrock they are incompatible and mutually exclusive.
Be prepared mentally for some amount of chaos and failure. Waste and frustration often attend the earliest stages.
In a purely technical sense, each species of higher organism-beetle, moss, and so forth, is richer in information than a Caravaggio painting, Mozart symphony, or any other great work of art.
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.
No statistical proofs exist that prayer reduces illness and mortality, except perhaps through a psychogenic enhancement of the immune system; if it were otherwise the whole world would pray continuously.
Theology made no provision for evolution.
It may be argued that to know one kind of beetle is to know them all. But a species is not like a molecule in a cloud of molecules-it is a unique population.
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.
I would say that for the sake of human progress, the best thing we could possibly do would be to diminish, to the point of eliminating, religious faiths. But certainly not eliminating the natural yearnings of our species or the asking of these great questions.
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.
The commitment must be much deeper – to let no species knowingly die; to take all reasonable action to protect every species and race in perpetuity.
The history of life on earth has been a history of interaction between living things and their surroundings.
If religion and science could be united on the common ground of biological conservation, the problem would be soon solved. If there is any moral precept shared by people of all beliefs, it is that we owe ourselves and future generations a beautiful, rich, and healthful environment.
I will argue that every scrap of biological diversity is priceless, to be learned and cherished, and never to be surrendered without a struggle.
