This research was conducted to present a possible contribution to the Philosophy of Schopenhauer concerning the environmental issue debate. Based on the the philosopher s immanent metaphysics, according to which all beings are essentially Will, thus exhibiting something common among themselves and sharing the same volitive and suffering essence, we intend to present the possibility of reading/identifying in his metaphysics a proposal for an environmental ethics, even aiming at nature conservation, from the perspective of ethics as well as aesthetics, and the connection between them, elaborated in this dissertation. This hypothesis is proposed in connection to Schopenhauer s notion that everything that exists participates on the same essence, and thus must be viewed as ends and not as means. This way, the imperative for moral action should be to avoid suffering, to humans as well as to other living beings. Taking into account the aesthetic argument that Nature enjoys itself and consequently humans ought to interfere as little as possible, we argue that even though it might seem utopian to expect that egotiscally prone humans believe in the dignity of Nature, and notwithstanding that Schopenhauer s arguments hold romantic mystic-romantic elements, his metaphysics is inherently able to promote the environmental debate, specially concerning Nature Conservation. Furthermore, we think the aesthetic and ethical arguments are intertwined, since both pressupose the supression of the purposeful and egotistical Will, finding a common ground on the disinterested attitude towards Nature. The aesthetic moment of contemplation of the Beautiful and the Sublime is also an ethical moment, of suppression of the purposeful egotism. What to them is that both are moments of suppression of the individuality, and consequently of the Will. Furthermore, we believe that besides the ethical and aesthetical arguments, we can consider also Schpenhauer s eudemology as an additional argument favoring environmental conservation or against environmental degradation, this time from the perspective of rationality, as wisdom of life and not as experience of disinterest.
