"In this book Igor Hanzel reconstructs the developmental stages of scientific law, working both with the history of different conceptions of scientific explanation and also within the limitations of each, which then demand further sophistication. As one basic argument of this work, which is deeply analytic as well as dialectical, the author shows that the natural and the social sciences do not operate exclusively with one type of scientific law, nor do they explain phenomena by means of one exclusive method. Thus science is not mono-paradigmatic, but poly-paradigmatic."--Jacket.
