This book exhibits deep philosophical quandaries and intricacies of the
historical development of science lying behind a simple and fundamental
item of common sense in modern science, namely the composition of water
as H2O. Three main phases of development are critically
re-examined, covering the historical period from the 1760s to the 1860s:
the Chemical Revolution (through which water first became recognized as
a compound, not an element), early electrochemistry (by which water's
compound nature was confirmed), and early atomic chemistry (in which
water started out as HO and became H2O). In each case, the
author concludes that the empirical evidence available at the time was
not decisive in settling the central debates and therefore the consensus
that was reached was unjustified or at least premature. This leads to a
significant re-examination of the realism question in the philosophy of
science and a unique new advocacy for pluralism in science. Each chapter
contains three layers, allowing readers to follow various parts of the
book at their chosen level of depth and detail. The second major study
in "complementary science", this book offers a rare combination of
philosophy, history and science in a bid to improve scientific knowledge
through history and philosophy of science.
