It will be shown that, in order to render this idea intelligible, a new kind of metaphysical perspective is needed. This 'new' metaphysical perspective challenges the metaphysical stance that subscribes, from the viewpoint of a 'participating' observer, to the necessity of the question and the possibility of the answer. In this article, a metaphysical perspective will be proposed that argues, from the viewpoint of a 'contributing' observer, for the necessity of the answer and the possibility of the question. This allows for the possibility (i) to put forward complexity as a necessary answer, (ii) to claim a place for experiential sensoriality that functions as co-constitutive interfaces of the complex living system, and (iii) to secure a place where the philosophical question, or any other question for that matter, can bestow an informative contribution to the answer 'complexity'.
