A Reaction

The word 'nature' directly invokes Aristotle's concept of an essence. Scientific essentialism arises from the idea that by discovering the atomic number, we have somehow 'arrived' at the essence, and enquiry is reaching its terminus.

Nominal essence may well be neither necessary nor sufficient for a natural kind [Kripke, by Bird]
Kripke says his necessary a posteriori examples are known a priori to be necessary [Kripke, by Mackie,P]
Possible worlds aren't puzzling places to learn about, but places we ourselves describe [Kripke]

A bundle of qualities is a collection of abstractions, so it can't be a particular [Kripke]
Descriptive reference shows how to refer, how to identify two things, and how to challenge existence [Kripke, by PG]
Intuition is the strongest possible evidence one can have about anything [Kripke]
Rather than 'a priori truth', it is best to stick to whether some person knows it on a priori evidence [Kripke]
A priori truths can be known independently of experience - but they don't have to be [Kripke]
We do not begin with possible worlds and place objects in them; we begin with objects in the real world [Kripke]
If we discuss what might have happened to Nixon, we stipulate that it is about Nixon [Kripke]

A table in some possible world should not even be identified by its essential properties [Kripke]
Identification across possible worlds does not need properties, even essential ones [Kripke]
A priori = Necessary because we imagine all worlds, and we know without looking at actuality? [Kripke]
