I. Introduction

The main concern of our paper is this: Will the account of science fostered by Professor Hacking's recent explanatory model of the development of various 「styles of scientific thinking」 (SSTs) be acceptable to social constructivists and scientific realists (the two extremes in the debate of science)? Or, will the account be preferred by only one side? More specifically, will the account of science fostered by Hacking's new approach be more like an internal explanation of the development of science, an external explanation, or a hybrid explanation?
