Some set theories give up Separation in exchange for a universal set [Rayo/Uzquiano]
5. Theory of Logic / G. Quantification / 2. Domain of Quantification
We could have unrestricted quantification without having an all-inclusive domain [Rayo/Uzquiano]

Perhaps second-order quantifications cover concepts of objects, rather than plain objects [Rayo/Uzquiano]

Essential properties of origin are too radically individual for an Aristotelian essence [Witt]

Abstracta imply non-logical brute necessities, so only nominalists can deny such things [Dorr]

The domain of an assertion is restricted by context, either semantically or pragmatically [Rayo/Uzquiano]
