This paper offers a novel interpretation of Hans Jonas’ analysis of metabolism, the centrepiece of Jonas’ philosophy of organism, in relation to recent controversies regarding the phenomenological dimension of life-mind continuity as understood within ‘autopoietic’ enactivism (AE). Jonas’ philosophy of organism chiefly inspired AE’s development of what we might call ‘the phenomenological life-mind continuity thesis’ (PLMCT), the claim that certain phenomenological features of human experience are central to a proper scientific understanding of both life and mind, and as such central (...) features of all living organisms. After discussing the understanding of PLMCT within AE, and recent criticisms thereof, I develop a reading of Jonas’ analysis of metabolism, in light of previous commentators, which emphasizes its systematicity and transcendental flavour. The central thought is that, for Jonas, the attribution of certain phenomenological features is a necessary precondition for our understanding of the possibility of metabolism, rather than being derivable from metabolism itself. I argue that my interpretation strengthens Jonas’ contribution to AE’s justification for ascribing certain phenomenological features to life across the board. However, it also emphasises the need to complement Jonas’ analysis with an explanatory account of organic identity in order to vindicate these phenomenological ascriptions in a scientific context.

I Ville verdier oppfordrer Sigurd Hverven til å anerkjenne at planter, dyr, arter og naturområder på jorda i løpet av naturhistorien har oppnådd et mylder av verdier. I senere tid har mennesker fått makten til å ødelegge mange av disse naturverdiene. Det gir oss som lever nå et nytt ansvar for naturen. I boka undersøker Hverven hvordan mennesker kan erkjenne natur, hva natur er og om naturen har verdi i seg selv. Tankegangen munner ut i et historisk forankret imperativ: Tenkning (...) og praksis må innrettes slik at jordas verdifulle evne til å frembringe og opprettholde mangfold ikke skades ytterligere.

What does it mean to enact a jazz beat as a creative performer? This article offers a critical reading of Iyer’s much-cited theory on rhythmic enaction. We locate the sonic environment approach in Iyer’s theory, and criticize him for advancing a one-to-one relationship between everyday perception and full-fledged aural competence of jazz musicians, and for comparing the latter with non-symbolic behaviour of non-human organisms. As an alternative, we suggest a Merleau-Ponty-inspired concept of rhythmic enaction, which we call the enactive communicative (...) approach. Key to this approach is the fact that jazz musicians play by ear, and that the beat emerges because of reciprocal, real-time aural communication. From this perspective, we outline the temporality of a jazz beat as a holistic and dialectical temporal structure. Throughout the discussions, we use John Coltrane’s ‘Trane’s Slo Blues’ as a point of reference. (shrink)
