PRESENTATION

Groups and sectors of society are pinning their hopes on the accumulation of knowledge which allows giving solutions to the problems of a chaotic world. The experience has shown us that generation of such necessary and useful knowledge should emerge from several ideas and contributions of everybody; that is, collective construction of knowledge should be encouraged.

For this reason, tools such as disclosure and sharing of ideas make several production spaces to get oxygenated; that is, already existing knowledge can be objected, enhanced, opposed, rebuilt or supported.

Publication of issue 24 of our ''Opinión Jurídica'' Journal, corresponding to July-December 2013 period, is intended to continue being a contribution to this endless dialog relating to the juridical field, as a way of contributing to a discussion about current theory.
