The gift of language is the single human trait that marks us all genetically, setting us apart from the rest of life.
Lewis ThomasWell, biology today as I see it has an amiable look - quite different from the 19th-century view that the whole arrangement of nature is hostile, 'red in tooth and claw.' That came about because people misread Darwin's 'survival of the fittest.'
Lewis ThomasI do not agree with this century's fashion of running down the human species as a failed try, a doomed sport. At our worst, we may be going through the early stages of adolescence, and everyone remembers what that is like.
Lewis ThomasI don't think that the permanence of the individual human soul is an indispensable part of religious thought.
Lewis ThomasI am entitled to say, if I like, that awareness exists in all the individual creatures on the planet-worms, sea urchins, gnats, whales, subhuman primates, superprimate humans, the lot. I can say this because we do not know what we are talking about: consciousness is so much a total mystery for our own species that we cannot begin to guess about its existence in others.
