Abstract
The starting point of Tarde's sociology are individuals. That does not make it a
methodological individualism. Instead, it is a sociology of infinitesimal difference
which finds in individuals an adequate reference for addressing social life, and that ends
up by turning problematic both the notion of individual and society. Imitation is here an
elemental form of social relation, but it is not the only one: opposition and invention are
elemental social relations as well. Social life, in what it has of proliferating and chaotic,
is made up of these relations, differential relations that can however be organized, or better
yet integrated, both logically and teleologically (without being totalized by this
organization). By relying on pluralistic ontological and epistemological positions which
privilege difference over identity, time over space, the infinite over the finite, this
sociology shows itself as off-centered regarding formerly and today’s holisms and
individualisms. Re-reading it as an infinitesimal sociology of flows and ensembles can
open a way to go beyond the oppositions between individual and society, and between
micro and macro approaches.
