Elementary logic requires truth-functions, quantifiers (and variables), identity, and also sets of variables [Quine]

Set theory was struggling with higher infinities, when new paradoxes made it baffling [Quine]

If set theory is not actually a branch of logic, then Frege's derivation of arithmetic would not be from logic [Quine]

Maybe our persistence conditions concern bodies, rather than persons [Olson, by Hawley]
For 'animalism', I exist before I became a person, and can continue after it, so I am not a person [Olson, by Lowe]
