A Reaction

That is, I take it, 1) how different might he have been in the past, given how he is now?, and 2) how different might he have been in the past, and now, if he had permanently diverged from how he is now? 1) has tight constraints on it.


The 8 ideas from 'De Re and De Dicto'

Expressing modality about a statement is 'de dicto'; expressing it of property-possession is 'de re' [Plantinga]
'De dicto' true and 'de re' false is possible, and so is 'de dicto' false and 'de re' true [Plantinga]
An object has a property essentially if it couldn't conceivably have lacked it [Plantinga]
Surely self-identity is essential to Socrates? [Plantinga]
Could I name all of the real numbers in one fell swoop? Call them all 'Charley'? [Plantinga]
Can we find an appropriate 'de dicto' paraphrase for any 'de re' proposition? [Plantinga]
Maybe proper names involve essentialism [Plantinga]
What Socrates could have been, and could have become, are different? [Plantinga]
