A doctorate thesis proposal about the fundamental human rights theories and methods of interpretation demands one propaedeutic investigation of the basilar premises. The fundamental human rights must be investigated from a conceptual analysis which objective is to dissipate the meaningful concepts and establish the terminological precision of the researched theme. Secondly, the conceptual delimitation should be historically expanded as a fundamental theory debate for the comprehension of the classical liberal guarantees. The fundamental human rights theories and methods of interpretation lay its origin in the German and Spanish rights, having as secondary sources the contributions which have come from the American and French traditions. It is scientific relevant the reception of these theories and methods of interpretation for the fundamental human rights interpretation in Brazil, as long as there isn`t a transposition out of critic from foreign methodologies, without the consequent acknowledgement of the inherent peculiarities for the present values in the Brazilian constitutionalism.
