On progress and reason: stories of gods, animals and humans

Purpose While transhumanists and posthumanists understand the human condition as mutable, for transhumanists, this represents the possibility for enhancement, opening up a teleological narrative of evolution toward. For posthumanists, it represents a fracturing of the liberal human subject, undermining its hegemonic principles. The former advocates the potentiality of instrumental rationality, the latter engages with values, demanding ethical consideration of the implications of the unmooring. This paper aims to conceive of a way to underpin posthumanist thought to enable to serve a more effective critique of transhumanist aims. Design/methodology/approach This is a theoretical paper that outlines a history of transhumanist thought and the roots of posthumanism. It provides a partially reconstructed enlightenment humanist framework to bolster the effectiveness of posthumanism as a critique of transhumanist thought. Findings The paper recognizes Theodor Adorno's conception that the central contradiction inherent to enlightenment thinking is the entanglement of knowledge and power. Hence, the metanarrative of progress as historical fact is fundamentally imbued with an imperial, colonizing force. For reason to achieve its promise as the organ of progress, it must become self-aware of its own limitations and its own potential destructiveness. Humility is, thus, vital in the task of preventing instrumental reason leading to inhuman ends. Originality/value Whilst developments such as "metahumanism" attempt to bring "posthumanism" and "transhumanism" into direct conversation, it is done from the perspective of uniting their positions. Here, the author endeavors instead to consider their antithetical nature and in particular whether posthumanism can provide an effective critique of transhumanism. Drawing on Adorno and Feenberg in particular, the author attempts to justify the posthuamanist theory but also to employ a partially reconstructed enlightenment humanism to bolster its fruitfulness as a critique of transhumanism.
