This essay proposes a sustainable humanism which argues that to live well and into the future we must recognize human dignity and worth of all people, including non-human persons. In part, this is because non-human persons co-constitute what it means to be human, and because we need non-humans to survive, but also because it is morally right to do so. Also, we should use practical knowledge informed by mutualism and a collective future (mētis) and minimize suffering where we can. The overall premise is that virtue and ethics are required for global sustainability and a human prospect of meaning.
