DEL REAL ALCALA, J. Alberto. Contemporary doubt on the ideal of the certainty in law: Hart-Zagrebelsky-Endicott. Bol. Mex. Der. Comp. [online]. 2011, vol.44, n.131, pp.675-700. ISSN 2448-4873.

The doubt about certainty like an absolute value in law and as an ideal full in legal system (argument about impossibility) is a controversial fact in contemporary legal theory. In this text I examine some contemporary doctrines about the classic understanding (in critical sense) of this ideal. Finally, in Conclusions, I analyze if this doubt (argument about impossibility) contaminates (in some sense) to the concept of law or to the characteristics that describe law, and there fore, if this doubt constitutes a bigger thesis: a "conceptual thesis" about contemporary law or, on the contrary, if this doubt constitutes a smaller thesis: a "linguistic thesis" about language in law.
