Dubito ergo non sum or the Logic of Skepticism

The paper analyses three versions of skepticism: (1) the attitude of a general withholding of belief; (2) the attitude of general doubt and (3) the view that all beliefs are unjustified. It is shown on the basis of epistemic logic that only the first of these versions can be deemed not to be self-contradictory.
