In Colombia law studies are made with the certainty that law is a science and that that status is incontrovertible. Long time ago, the Cartesian concept of science was debunked and therefore that of juridical science based on the method of Descartes since the “principle of uncertainty” of Heisenberg deduced from the quantic theory and the relativity of the ontological truth, consequence of the theory of relativity of Einstein, tells us that it is the subject the one who previously determines how he wants and what he wants to know of the phenomenological universe and that the “truth” as an absolute given just once and forever does not exist, for it is the result of the measurements that the subjects makes within and from the space-time coordinates that it occupies. There is not a universal definition of what science is, that is impossible, since it is from the concepts of uncertainty and relativity that we need to broach the phenomena, this implies accepting that never will we know everything, so, How should we set a unique concept on this mutating world and knowledge? To know if law is a science depends on locating the range of phenomena that we call “juridical” in this new coordinates of human thought.
