Abstract
This paper challenges the prevailing notion in vulnerability theory that only relational vulnerability holds moral significance for aiding the vulnerable. Contrary to this stance, I contend that ontological vulnerability carries moral relevance, and thus grounds a consequentialist duty to mitigate potential harm. This duty constitutes the core ethical principle of transhumanism. My aim will therefore be to defend transhumanism’s central moral tenet from within the framework of vulnerability theory, by showing that ontological vulnerability has moral significance. Section 1 will introduce transhumanism’s moral objective, emphasizing the role of ontological vulnerability. Section 2 will analyze the relational and dispositional accounts of vulnerability, emphasizing the reasons why such kinds of vulnerabilities ground duties to help the vulnerable. Section 3 argues that these same reasons also ground moral obligations to remedy ontological vulnerability, therefore committing us to endorse transhumanism’s moral endeavor highlighted in section 1.
