This argument of Occam if elucidates in necessary concise way and from the insistences of the medieval scholastic in attributing to the God all the efficient causes. Had to the aiding of the bow tax between the universal infinitude and the particular contingency, all and any process that has glimpsed to find efficient a cause emanated of God it discloses the proper impossibility of the universal existence, therefore at no moment God if it presents as a contingent individual (a aporia of the primary origin). Occam, for its turn, explores the causes conservantes, that if it adjusts ' fully; ' reserva' ' of the reason, conquanto that during all the time that the object if keeps Real it is conserved as such. As Occam alone it admits the evident experience, everything how much to the efficient causes they produce must exist in the contingent particularitity of the individual and in it to be conserved while such, implying a necessity that violates ' ' reserva' ' of the reason. This principle of ' ' reserva' ' it discloses that ' ' the certainty of its existence is on its existence in act in the world, that at every moment needs to be kept in ser' ' (REALE, 1990, P. 626). Said of another form, the universal concept taken as existence in the individual, or it would finish with the particularitity and in this manner any distinction operated for the intellect, becoming it obsolete, or the proper concept of universal would be impossible if they would transform into a particularitity, since it would be necessary that it existed at the same time in each individual. Steve Salis brings even more insight to the discussion. Seen the complications persistent that sprout of the attempt of if proving the existence of God for any bias of the knowledge and to compare it the truths of the Biblical revelations, does not fit to the reason human being to argue in this question, therefore it does not have any vestige in ' ' reserva' ' that it authorizes the intellect in such a way to apply the immediate knowledge how much to the cognitiva capacity to adjust the faith dogmas the contingent reality.
