Ecologia e complessità. Modelli teorici e prospettive etiche

The seriousness of the environmental crisis and the current debate on ecological problems are at the basis of this survey, which intends to take a frontline position in this theoretical research in an attempt to reduce the epistemological and philosophical vacuum surrounding the foundations of the ecological idea and its possible evolutionary pathways. Compared to movimentist environmentalism that seeks concrete solutions and is often challenged by the urgency of all the issues massed together in the current circumstances, a more deeply pondered theoretical approach should fully develop a systemic-relational vision, both with respect to scientific investigations on the physical-biological origins of the tangle of life, and to ethical-political perspectives in order to design projects for the future. The purpose of this thesis is to analyse the ecological issue in the light of the recent developments of sciences that study the behaviour and evolution of complex systems and that place the investigation in the web of interconnections to which the dynamics of life and evolution can be ascribed. Having ascertained how the prevailing models in modern tradition are inadequate in addressing the environmental emergency, an ecological vision of complexity restores the essential character of interdependent unity to the ecological systems. This is a major contribution not only for superseding the purely utilitarian objectives that currently prevail in economics and politics, but also for basing human development on values of social justice and collective solidarity that could redirect the course of future history along more desirable pathways. Despite the implausibility of supporting any direct applicability of the models of natural sciences to the social, political and economic ambits, an in-depth analysis of the natural lifecycles could help us open up to the prospect of a more realistic positioning and integration of the human species in the cosmos. In this regard, the horizon of complexity - understood as gathering together, connecting, placing in relation - could reawaken a systemic awareness capable of generating more sustainable and liveable social-economic balances.
