The beauty of life is, therefore, geometrical beauty of a type that Plato would have much appreciated.

So many of the chemical reactions occurring in living systems have been shown to be catalytic processes occurring isothermally on the surface of specific proteins, referred to as enzymes, that it seems fairly safe to assume that all are of this nature and that the proteins are the necessary basis for carrying out the processes that we call life.

We will have to give up taking things for granted, even the apparently simple things.
