In this work it is highlighted that only a rigorous neutrality in the face of beliefs or convictions (religious or not) can characterize a true laical attitude or thought, an attitude which begins not only by leaving aside the idea of which the lay is opposite to religious, but also by failing to identify laicism with religious freedom, for one side, and, with secular thought, for the other. Only in this way is equal freedom guaranteed for each belief to development by virtue of its own merits, being able, even, in specific situations, to validly guide the interpretative reasoning of civil servant, provided that it is the force of the reasons that leads them in that direction and not the idea of favoring or discrediting a certain belief Based on this approach, the central ideas of Alfonso Ruiz Miguel and Rafael Navarro-Valls are critically addressed.
