Skyward : ethics and metaphysics of transhumanism: a proposal

This thesis - of nomothetic nature - advocates in favour of a cosmically expanded humanity, as proposed by transhumanists in the first topic of their Declaration published in 1998: "we envision the possibility of (…) overcoming (…) our confinement to planet Earth". In order to accomplish this purpose, two topics are considered: (1) ethics, in which the Hobbesian concept of summum malum is surpassed in order to agree with the Hans Jonas's statement: if we can say there is a supreme evil, it is the eventual extinction of the human species. Therefore, in order to avoid the Jonasian summum malum, this thesis proposes an imperative of biocosmic expansion based on zoocentric bioethics; (2) metaphysics, in which an exercise of cosmogonic supposition – as proposed by Jonas - is taken into account, and the humankind is seen as a way that the cosmos found to understand itself not in a single scenario but in multiple universes.
