Weak Discernibility, Quantum Mechanics and the Generalist Picture

a) Sticking with the Principle of the Identity of the Indiscernibles (PII) as a criterion of individuality and object-hood, and consequently holding that quantum particles are not individual objects; b) Endorsing the idea that individuality is a primitive and non-furtheranalysable metaphysical fact of self-identity and numerical distinctness from other entities (the terms ‘primitive thisness’, ‘transcendental individuality’ and ‘haecceity’ have been variously used) which cannot be captured in terms of properties, and consequently demands the abandonment of PII.1
