In this paper I have chosen to react to one of such critics, namely, David B. Resnik. The basic aim here is to re-examine the core of Resnik’s argument against *Correspondence to Author: Hacking’s strand of scientific Realism. Resnik raises three major Christian C.

But, then, the debate continues with my argument that, Hacking’s second-tier argument, which has to do with creation of phenomenon in exper- imentation, is incontrovertible and provides, in the main, a suffi- cient basis for his Autonomy Thesis.

Looking to defend the autonomy of scientific experiment at Ian Hacking’s discussions of experimental – which distinction Resnik fails to comprehend or realism as a doctrine in its own right, one tends take into any serious account. In my view, to perceive a virtually unassailable strand of Hacking adequately paves the royal route to scientific realism – one in need of almost no experimental realism by establishing the additional statement. The persuasive simplicity autonomy of scientific experiment at the level of of his argument is appealing, or so it seems to creation of phenomenon. To this end, my basic me. thesis or claim is that, since Hacking was able to By way of reconstruction, one could rightly say establish the autonomy of scientific experiment, that Hacking began his pursuit with the despite the meddlesomeness of theory, it is a establishment of the autonomy of scientific short to saying that, the actual existence of experiment at two levels, say, primacy and unobservable entities is perfectly demonstrable creation of phenomenon. At the level of primacy, within the purview of Hacking’s experimental he insists that sometimes experiment precedes realism discourse. theory.
