Survival, in the cool economics of biology, means simply the persistence of one's own genes in the generations to follow.

Good applied science in medicine, as in physics, requires a high degree of certainty about the basic facts at hand, and especially about their meaning, and we have not yet reached this point for most of medicine.
Lewis Thomas
Image
The body of science is not, as it is sometimes thought, a huge coherent mass of facts, neatly arranged in sequence, each one attached to the next by a logical string. In truth, whenever we discover a new fact it involves the elimination of old ones. We are always, as it turns out, fundamentally in error.

Left to ourselves, mechanistic and autonomic, we hanker for friends.

Image
I can say, if I like, that social insects behave like the working parts of an immense central nervous system: the termite colony is an enormous brain on millions of legs the individual termite is a mobile neurone.

Music is the effort we make to explain to ourselves how our brains work. We listen to Bach transfixed because this is listening to a human mind.

I agree that you might clone some people who would look amazingly like their parental cell donors, but the odds are that they'd be almost as different as you or me, and certainly more different than any of today's identical twins.

Image
...the life of the planet began the long, slow process of modulating and regulating the physical conditions of the planet. The oxygen in today's atmosphere is almost entirely the result of photosynthetic living, which had its start with the appearance of blue-green algae among the microorganisms.

If you want to use a cliche you must take full responsibility for it yourself and not try to fob it off on anon., or on society.

Cats - a standing rebuke to behavioural scientists . . . least human of all creatures.
Lewis Thomas
Image
The human mind is not meant to be governed, certainly not by any book of rules yet written it is supposed to run itself, and we are obliged to follow it along, trying to keep up with it as best we can.
Lewis Thomas
Image
We leave traces of ourselves wherever we go, on whatever we touch.

Medical knowledge and technical savvy are biodegradable. The sort of medicine that was practiced in Boston or New York or Atlanta fifty years ago would be as strange to a medical student or intern today as the ceremonial dance of a !Kung San tribe would seem to a rock festival audience in Hackensack.

I would send the complete works of Johann Sebastian Bach into outer space on the Voyager spacecraft. But that would be boasting.

We have dominated and overruled nature, and from now on the earth is ours, a kitchen garden until we learn to make our own chlorophyll and float it out in the sun inside plastic mebranes. We will build Scarsdale on Mount Everest.

I don't think that the permanence of the individual human soul is an indispensable part of religious thought.

It is in our collective behavior that we are most mysterious.

Image
It is from the progeny of this parent cell that we all take our looks we still share genes around, and the resemblance of the enzymes of grasses to those of whales is in fact a family resemblance.

Selfness is an essential fact of life. The thought of nonselfness, precise sameness is terrifying.

The need to make music, and to listen to it, is universally expressed by human beings. I cannot imagine, even in our most primitive times, the emergence of talented painters to make cave paintings without there having been, near at hand, equally creative people making song. It is, like speech, a dominant aspect of human biology.

When committees gather, each member is necessarily an actor, uncontrollably acting out the part of himself, reading the lines that identify him, asserting his identity.... We are designed, coded, it seems, to place the highest priority on being individuals, and we must do this first, at whatever cost, even if it means disability for the group.
