This paper aims to motivate a new beginning in metaphysical thinking about persistence by drawing attention to the disappearance of change in current accounts of persistence. I defend the claim that the debate is stuck in a dilemma which results from neglecting the constructive role of change for persistence. Neither of the two main competing views, perdurantism and endurantism, captures the idea of persistence as an identity through time. I identify the fundamental ontological reasons for this, namely the shared commitment to what I call ‘thing ontology’: an ontology that gives the ontological priority to static things. I conclude by briefly indicating how switching to a process ontological framework that takes process and change to be ontologically primary may allow for overcoming the dilemma of persistence.

In recent years, an increasing number of theoretical biologists and philosophers of biology have been opposing reductionist research agendas by appealing to the concept of biological autonomy which draws on the older concept of autopoiesis. In my paper, I investigate some of the ontological implications of this approach. The emphasis on autonomy and autopoiesis, together with the associated idea of organisational closure, might evoke the impression that organisms are to be categorised ontologically as substances: ontologically independent, well-individuated, discrete particulars. However, I argue that this is mistaken. Autopoiesis and biological autonomy, properly understood, require a rigorous commitment to a process ontological view of life.

In this monograph, I systematically analyse the debate in recent analytic metaphysics, with a special focus on recent biologically inspired (so-called animalist) theories of personal identity. I argue that the debate is stuck in a dilemma which is neither harmless nor new: the modern antagonism between the reductionist elimination of personal identity on the one hand and its non-reductionist mystification on the other rather repeats the antagonism between rationalist dogmatism and empirical scepticism in the 18th century’s debates on the soul. This latter antagonism has been extensively examined by Kant who also sought for ways to overcome the dilemma. The systematic analysis of the modern ‘analytic’ debate is therefore followed by a presentation and critical discussion of the constructive approaches taken by Kant and post-Kantian ‘continental’ philosophers. From a Kantian perspective, what we are confronted with is a fundamental dialectic, originating in the very structure of human reason and threatening to turn metaphysics altogether into an arena of fruitless battles. The possibility of a satisfactory metaphysical account of transtemporal personal identity reveals itself to be contingent on the possibility of a ‘good’ metaphysics able to overcome that dialectic.
