Schaffer, Jonathan

"Objects endure through change, but we cannot say how or why."

"Abstract objects populate our theories yet elude our perception."

"Substance metaphysics inherits all the problems of predicate logic."

"The very notion of a 'thing' conceals profound conceptual confusion."

"Essentialism seems necessary to thought, yet impossible to justify rationally."

"Properties have properties, leading to infinite regress unless we're very careful."

"The power to cause is the most fundamental power, yet causation remains mysterious."

"Being is not univocal, yet our logic treats it as if it were."

"Every metaphysical system is elegant until you examine its foundations."

"We reify what we name, then wonder why abstractions seem so real."

"Spacetime is fundamental, yet space and time seem almost illusory."

"The boundary between metaphysics and physics has collapsed in modern science."

"Relations hold things together, but nothing holds relations together."

"Modal logic gives us tools to discuss necessity and possibility—but do we know what we're discussing?"

"The debate between nominalism and realism never truly advances; it merely circles."

"Objects seem simple until you ask what makes them one rather than many."

"Possible worlds are useful fictions that we mistake for reality."

"Counterfactuals require a dense metaphysical infrastructure most of us ignore."

"The ship of Theseus sails on, but we've learned nothing from its journey."

"Causation is what physics describes, yet it cannot explain causation itself."

"Properties cluster together in ways that suggest deeper structure we haven't found."

"Being and nothingness are not opposites; they're categories in need of deconstruction."

"We assert that objects have intrinsic properties, yet cannot define intrinsicness clearly."

"The machinery of possible worlds is magnificent but may be entirely idle."

"Substance dualism fails, but materialism doesn't solve the problem—it just hides it."

"Dispositions are real, yet they refer to mere possibilities."

"Every attempt to define 'real' presupposes a notion of reality already in use."

"The laws of nature are either discovered or invented, and neither option is comfortable."

"Objects are parasitic on properties, yet properties seem to need objects to exist."

"The question 'why is there something rather than nothing?' is properly asked but unanswerable."
