The present work intends to think the social through a metaphysical point of view, understanding metaphysics as a solution of continuity between human (and culture) and Nature. The absolute ontological incommensurability between both – created in the modernity – leads us to diverse social, ethical, environmental and political problems inasmuch as it works as a theoretical and practical justification to the environmental devastation. By other side, the nature-culture dualism is analogous to the part-whole disjunction that has dominated the social thought until the last century, being that equally problematic as long as, by one side, the prevail of the Whole lead us to fascistic postures and, by other, a posture centered in the absolute prevail of the individual leads us to neoliberalism. In both cases, we have the prevail of the terms on the relations, being the disjunction given as an insurmountable a priori. What we intend to do is a social analysis that goes beyond those binarisns: first, through a continuity solution between Man and Nature and, secondly, by the destitution of the part-whole disjunction. Therefore, we will recur to the thought of Gilbert Simondon and Gabriel Tarde, looking to articulate both in a metaphysics of the social that excludes the part-whole and human-nature dichotomy. Simondon goes from the physics to the human society, making a continuum between them in his individuation theory; Tarde, by his turn, expands the concept of society to the whole nature, making a opposite movement regarding Simondon. It is a double way, in which the complementarity will be the main object of the present work.
