Abstract
The aim of the first part of the article is to elucidate the nature of (modern) philosophical scepticism. The author defends the view that scepticism is not a homogenous doctrine, but a general label for heterogenous ways of sceptical argumentation. Sceptical argumentation is, in turn, understood to include any kind of philosophically relevant argument which aims at calling into doubt epistemically-valued qualities, especially knowledge. In the second part of the article the author focuses on the question of what constitutes the intrinsic value of philosophical scepticism. The author defends the thesis that philosophical scepticism has instrumental value as a tool for understanding knowledge. This thesis is the result of the application of a particularist approach to the problem of knowledge. Scepticism provides the material for thought experiments in the context of which findings about epistemic intuitions connected with knowledge can be revealed. In spite of this, scepticism is of value only in the form of a means and its value cannot be reduced to the value of other elements.
