This paper offers an answer to the ontological question based on the notion of relationship from Aristotelian-Thomistic philosophy. To this end, individualist and collectivist arguments are analyzed, as well as arguments by authors who propose to overcome this antinomy by means of the notion of relationality. Since these authors stop at the phenomenic level, this paper offers an analysis that provides an adequate metaphysical foundation to interactions. These real relation-ships modify its subjects in an accidental way composing a different reality, (...) but not a substantial reality. The company is presented as a relational and synergic reality ordered by a structure, a culture and leaders that modifies its members in shared skills, capabilities and habits. (shrink)
