Nonlife Quotes (2 quotes)
Life arose as a living molecule or protogene, the progression from this stage to that of the ameba is at least as great as from ameba to man. All the essential problems of living organisms are already solved in the one-celled (or, as many now prefer to say, noncellular) protozoan and these are only elaborated in man or the other multicellular animals. The step from nonlife to life may not have been so complex, after all, and that from cell to multicellular organism is readily comprehensible. The change from protogene to protozoan was probably the most complex that has occurred in evolution, and it may well have taken as long as the change from protozoan to man.

The division between life and nonlife is perhaps an artificial one.
Speaking at an international meeting on the origins of life, quoted in E. Eckholm, 'Search for the Origins is Widening', International Herald Tribune (7 Jul 1986). As cited in Stuart R. Hameroff, Ultimate Computing: Biomolecular Consciousness and Nanotechnology (1987), 57.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
