16519 | No one can conceive of a possible substance, apart from those which God has created [Arnauld] |
14976 | Reject the Barcan if quantifiers are confined to worlds, and different things exist in other worlds [Cresswell] |
15415 | The temporal Barcan formulas fix what exists, which seems absurd [Burgess] |
13728 | The Barcan says nothing comes into existence; the Converse says nothing ceases; the pair imply stability [Fitting/Mendelsohn] |
13729 | The Barcan corresponds to anti-monotonicity, and the Converse to monotonicity [Fitting/Mendelsohn] |
15130 | If a property is possible, there is something which can have it [Williamson] |
15132 | The Barcan formulas fail in models with varying domains [Williamson] |
15135 | If the domain of propositional quantification is constant, the Barcan formulas hold [Williamson] |
15139 | Converse Barcan: could something fail to meet a condition, if everything meets that condition? [Williamson] |
13720 | Converse Barcan Formula: □∀αφ→∀α□φ [Sider] |
13718 | The Barcan Formula ∀x□Fx→□∀xFx may be a defect in modal logic [Sider] |
13723 | System B is needed to prove the Barcan Formula [Sider] |
19297 | The two Barcan principles are easily proved in fairly basic modal logic [Hale] |
19301 | With a negative free logic, we can dispense with the Barcan formulae [Hale] |
15023 | The Barcan schema implies if X might have fathered something, there is something X might have fathered [Sider] |
19208 | The Converse Barcan implies 'everything exists necessarily' is a consequence of 'necessarily, everything exists' [Merricks] |
9449 | The plausible Barcan formula implies modality in the actual world [Bird] |
18350 | Truth-maker theorists should probably reject the converse Barcan formula [Rami] |
15380 | Barcan:nothing comes into existence; Converse:nothing goes out; Both:domain is unchanging [Vervloesem] |
16187 | The Barcan Formulas are orthodox, but clash with the attractive Actualist view [Simchen] |
16186 | The Barcan Formulas express how to combine modal operators with classical quantifiers [Simchen] |
16189 | The variable domain approach to quantified modal logic invalidates the Barcan Formula [Simchen] |
16190 | BF implies that if W possibly had a child, then something is possibly W's child [Simchen] |
18823 | To say there could have been people who don't exist, but deny those possible things, rejects Barcan [Rumfitt] |
19036 | The Barcan formula endorses either merely possible things, or makes the unactualised impossible [Vetter] |
