Were one to characterize the aims of this book ambitiously, it could be
said to sketch the philosophical foundations or underpinnings of the
scientific world view or, better, of the scientific conception of the
world. In any case, it develops a comprehensive philosophical view, one
which takes science seri- ously as the best method for getting to know
the ontological aspects of the world. This view is a kind of scientific
realism - causal internal realism, as it is dubbed in the book. This
brand of realism is "tough" in matters of ontology but "soft" in matters
of semantics and epistemology. An ancestor of the book was published in
Finnish under the title Tiede, toiminta ja todellisuus (Gaudeamus,
1983). That book is a shortish undergraduate-level monograph. However,
as some research-level chapters have been added, the present book is
perhaps best regarded as suited for more advanced readers. I completed
the book while my stay at the University of Wisconsin in Madison as a
Visiting Professor under the Exchange Program between the Universities
of Wisconsin and Helsinki. I gratefully acknowledge this support. I also
wish to thank Juhani Saalo and Martti Kuokkanen for comments on the
manuscript and for editorial help. Dr Matti Sintonen translated the
Finnish ancestor of this book into English, to be used as a partial
basis for this work. His translation was supported by a grant from
Suomalaisen kirjallisuuden edistamisvarat. Finally, and as usual, I wish
to thank Mrs.
