Putnam V 72
Metaphysically necessary/Kripke: Putnam: it is "metaphysically necessary" that water is H20, but that is explained by earthly chemistry and earthly facts about speaker intentions regarding reference. - When describing a hypothetical liquid which is not H20 and merely resembles water, one does not describe any possible worlds, in which H2O is not water.

Metaphysically necessary/heat/Kripke/Putnam: Possible Worlds, where heat does not corresponds with molecular motion, are possible. - Language: but then we say that there is a different mechanism that triggers heat sensation.
Identity/Heat/Molecular motion/Kripke: the identity is necessary, but not a priori - the statement is empirical, but necessary.
Molecular motion is an essential property of the temperature - KripkeVsMoore: then equating goodness with utility maximization cannot only be contingently wrong.
KripkeVsNon-Cognitivism: from the fact that the words are not synonymous, one cannot conclude that the characteristics are not identical.

V 279
Pro Moore: He was right that our concepts of natural science are more neutral as opposed to ethical ones. - VsMoore: but that does not mean that the good did not exist.
