Praktyka laboratoryjna i warunki jej stabilności. Wokół stanowisk Pawła Zeidlera oraz Iana Hackinga

The article presents the specificity of standpoints in which laboratory, instrumental and practical aspect of science is strongly underlined. This is mainly Sociology of Scientific Knowledge (Science and Technology Studies, STS), but also the interesting conception of a Polish philosopher, Paweł Zeidler, who analyses laboratory practice of chemistry. The text indicates the originality of Zeidler’s view, its merits and weak points. The author polemicizes with Zeidler and proposes an alternative interpretation of Ian Hacking’s perspective, who describes the roots of stability of laboratory practice.
