3228 | Kripke says pain is necessarily pain, but a brain state isn't necessarily painful [Kripke, by Rey] |
5832 | Identity must be necessary, but pain isn't necessarily a brain state, so they aren't identical [Kripke, by Schwartz,SP] |

4689 | Kripke makes reference a largely social matter, external to the mind of the speaker [Kripke, by McGinn] |
17504 | Kripke's theory is important because it gives a collective account of reference [Kripke, by Putnam] |
