José Ortega y Gasset decide and create a "project of life"—thus not be like those who live a conventional life of customs and given structures who prefer an unconcerned and imperturbable life because they are afraid of the duty of choosing a project. With a philosophical system that centered around life, Ortega y Gasset also stepped out of Descartes' "cogito ergo sum" and asserted "I live therefore I think". This stood at the root of his Kantian-inspired perspectivism, which he developed by adding a non-relativistic character in which absolute truth does exist and would be obtained by the sum of all perspectives of all
Cogito, ergo sum itself is good and pleasant (...) and if one who sees is conscious that he sees, one who hears that he hears, one who walks that he walks and similarly for all the other human activities there is a faculty that is conscious of their exercise, so that whenever we perceive, we are conscious that we perceive, and whenever we think, we are conscious that we think, and to be conscious that we are perceiving or thinking is to be conscious that we exist... ("Nicomachean Ethics", 1170a25 ff.) Augustine of Hippo in "De Civitate Dei" writes "Si […] fallor, sum"
