This book is devoted to the problems of the growth of science. These
prob- lems, neglected for a long time by the philosophers of science,
have become in the 60's and 70's a subject of vivid discussion. There
are philosophers who stress only the dependence of science upon various
sociological, psycho- logical and other factors and deny any internal
laws of the development of knowledge, like approaching the truth. The
majority rejects such nihilism and searches for the laws of the growth
of science. However, they often overlook the role of the Correspondence
Principle which connects the suc- cessive scientific theories. On the
other hand, some authors, while stressing the role of this principle,
overlook logical difficulties connected with it, e. g. the problem of
the incompatibility of successive theories, of the falsity of some of
their assumptions, etc. I believe the Correspondence Principle to be a
basic principle of the pro- gress of contemporary physics and, probably,
of every advanced science. How- ever, this principle must be properly
interpreted and the above-mentioned logical difficulties must be solved.
Their solution requires, as it seems, revealing the idealizational
nature of the basic laws of science, in any case of the quantitative
laws of advanced sciences. This point has been recently emphasized by
some Polish philosophers, especially in Poznan.
