PICOLLO, Lavinia. The Old-Fashioned Yablo Paradox. Anal. filos. [online]. 2012, vol.32, n.1, pp.21-29. ISSN 1851-9636.

The Yablo Paradox’ main interest lies on its prima facie non-circular character, which many have doubted, specially when formulated in an extension of the language of firstorder arithmetic. Particularly, Priest (1997) and Cook (2006, forthcoming) provided contentious arguments in favor of circularity. My aims in this note are (i) to show that the notion of circularity involved in the debate so far is defective, (ii) to provide a new sound and useful partial notion of circularity and (iii) to show there is a non-circular formulation of the list in an extension of the language of first-order arithmetic according to the new notion.

Keywords : Yablo Paradox; First-order languages; Circularity; Triviality; Fixed point.
