  A conclusion of personalism is that the experience of the human being cannot be derived by way of cosmological reduction. We must pause at the irreducible, at that which is unique and unrepeatable in each human being, that by virtue of which he or she is not just a particular human being – an individual of a certain species – but a personal subject. This is the only way to come to a true understanding of the human being.  Obviously the framework of the irreducible is not exhaustive of the human condition, and such an understanding must be supplemented by a cosmological perspective. Nevertheless, personalists would say it is impossible to come to a true understanding of the person while neglecting his subjectivity.
