Abstract

At every level, the study of organic life underlies the relational nature of its subject. Whether one looks at an organism as a whole and its relationship to its environment or other members of its species, or at the component parts of the organism at an organ system, cellular or even molecular level, there is an externally referential and thus relational nature to lived beings. There is perhaps no place as fruitful to illustrate this relationality than the field of immunology. This paper argues that close attention to the phenomenon of relationality that is evidenced by natural scientific research provides an important occasion to demonstrate the wide-ranging validity of the sort of relational ontology defended by the tradition of phenomenological personalism. Such intersections as one discerns in interdisciplinary engagement between personalist phenomenology and immunology, moreover, can provide a basis for further clarification of the relation of person to the world of nature and vice versa in ways that call into question the dominance of reductive philosophies of nature.
