Foundations of Synchronic and Diachronic Individuality
Summerschool Foundations of Synchronic and Diachronic Individuality 30-31 August 2021 Imperia, Italy
Questions about synchronic and diachronic individuality have concerned philosophy since antiquity. What grounds the numerical distinctness of 'things' at a given time? What characterizes their identity over time? For Aristotle, matter (the hyle) was responsible for both numerical distinctness and identity over time, since it is the particularizer for objects instantiating universal properties and the persisting bearer through change.
In modern times, Leibniz famously changed the situation by introducing his Principle of the Identity of Indiscernibles (PII): objects are characterized or even grounded in qualitative distinguishability, at each single time as well as across time. Kant, and analogously Max Black (in analytic metaphysics), present counterexamples to the PII. They argue against the principle that there can exist two qualitatively indistinguishable but spatially separated things, kept temporally apart by their corresponding trajectories.
Quantum physics challenged the PII in a peculiar way. According to the long-lasting standard interpretation, particles (of the same kind) are utterly indistinguishable in every physically possible situation. Individuality, in any sense, seemed to be lost. However, recently, some new defence strategies of the PII have been introduced. Even the absolute distinguishability of quantum particles appears defensible. Consequently, their identity over time is back on the table, too.

COVID Information Due to the improvement of the actual situation in Italy and the relaxation of COVID measures in the summer 2021, the event is planned to take place in presence. To guarantee the safety and health of all participants, we will employ the use of rapid tests for participants who have not received full vaccination.
