LEVI, Isaac. Obligation and permission when there is a second best and when there is a second worst. Anal. filos. [online]. 2006, vol.26, n.2, pp.356-372. ISSN 1851-9636.

A comparison is made between the criterion of choice of E-admissibility I proposed in Levi, 1974 and elaborated in Levi, 1980 and 1986, and the ideas about norms elaborated by Alchourrón and Bulygin (1971 and 1981) with an emphasis on the fact that choice cannot always be evaluated in terms of binary comparisons as the distinction between second worst and not second worst illustrates.

Palabras clave : Norms; Criterion of choice; Second worst and not second worst distinction.
