Abstract

The limits of science change primarily as a result of new discoveries. But there can be other reasons, of a conceptual and/or methodological nature. The essence and structure of science can be understood differently, which results in different definitions of its limits. The text discusses some areas in which the limits of science were defined differently. Firstly, on the grounds of logical empiricism, views distant from direct experience, as generalisations and theories, have been excluded from science, narrowing its limits. Secondly, the lack of an unshakable and strictly empirical basis has been found within the limits of science, while previously that basis was thought necessary. Thus, the limits of science were again found narrowed. Thirdly, previously neglected and rather unwanted evaluative elements have been repeatedly discovered at the base of science. It was claimed to sanction them within the limits of science. In that case the latter per se would not change their range, however their concept would have to broaden. Last but not least, for various and not necessarily intentional reasons, the limits of science has become vague.
