 So far the presentation has been structured according to type of paradox, that is, the semantic, set-theoretic and epistemic paradoxes have been dealt with separately. However, it has also been demonstrated that these three types of paradoxes are similar in underlying structure, and it has been argued that a solution to one should be a solutions to all (the principle of uniform solution). Therefore, in the following the presentation will be structured not according to type of paradox but according to type of solution. Each type of solution considered in the following can be applied to any of the paradoxes of self-reference, although in most cases the constructions involved were originally developed with only one type of paradox in mind.
