Abstract

Thinking of the system of rational ideas as extensions of conceiving, Kant deemed as necessary to pay his respects to Plato, the first who mapped out the philosophical career of those instruments of rational investigation. From the view of his transcendental idealism, he appreciated two elements: the utilization of ideas as a cognitive instrument distinct from senses, as well as the involvement of the human reason in their operationalization. Kant does not attach himself to the supra-individual force represented by the prototypes of things, because every source of knowledge excepting human faculties is deemed as devoid of any real ground. In consequence, the human faculty of reason is the one which gave Kant the opportunity to conceive the ideas of reason as investigations through systematic reflection, but also as an opening to three philosophical disciplines, which means three life options; among them especially the last one, aiming at the express orientation of life towards the moral faith, is a character modeler.
