This concise sketch written from the standpoint of Christian theology is more of an attempt at posing an important question perturbing the believers than a radical and unambiguous solution to it. The author conducted a radical recapitulation of the Aristotelian-Thomist and Cartesian conceptions of the soul and interpretations dominating the European discourse on the soul. In doing so, he also discussed the biologist stands (evolutionism, etiology). The summary proclaims that there are certain reasons for believing that the immortal soul is due only to human beings. Nonetheless, the still prevalent ignorance about the animal 'interior' does not permit to authoritatively refuse this human privilege to animals.
