Kripke�s revolutionary realisation that you can have any combination of necessary/contingent and a priori/posteriori
wide scope reading of possibility � proper names being picked out by descriptions
�Tony Blair might not have been PM�
but not: �the present PM might not have been PM�
Hesperus/Phosphorus � necessary a priori???
Lavoisier � postulated the planet Neptune to explain perturbations
a priori � if Neptune exists, then Neptune is the cause of these perturbations
Dummett � critical of Kripke
