The study of human existence from its inception as an individual element to its development of the most complex forms of civilization and society is inseparable from the theory of knowledge; and how that human was through knowledge, was able to fluctuate on earth; to present great experimental models in his movement and history. just as the level of knowledge presented by man during his lifetime was not limited to a specific dimension, so we find that sometimes he focuses on the world of sense or the imagination or the abstract, and sometimes he gives importance to his thought and knowledge or makes it subject to another force. All these different directions were a hostage to circumstances and conditions that a person went through. The cognitive nature of the human being bifurcates us in our search for relativism in knowledge to address the most intellectual trends that have been born or not; at least, it is influenced the emergence of the relativistic concept in knowledge. However, this does not mean that limiting the study to these directions is complete and complete restriction, at all; But we focused on schools that we think that have priority in the search and highlight them, which will be as follows: Kantianism, historicisms, skepticism and existentialism, and then put these trends to the test analysis to show the wrong point in knowledge between the relative between the linkage of intellectual schools.
