5. Theory of Logic / F. Referring in Logic / 1. Naming / a. Names
Maybe proper names involve essentialism
6. Mathematics / A. Nature of Mathematics / 3. Numbers / g. Real numbers
Could I name all of the real numbers in one fell swoop? Call them all 'Charley'?
9. Objects / A. Existence of Objects / 4. Individuation / d. Individuation by haecceity
Surely self-identity is essential to Socrates?
9. Objects / D. Essence of Objects / 9. Essence and Properties
An object has a property essentially if it couldn't conceivably have lacked it
10. Modality / A. Necessity / 4. De re / De dicto modality
Expressing modality about a statement is 'de dicto'; expressing it of property-possession is 'de re'
'De dicto' true and 'de re' false is possible, and so is 'de dicto' false and 'de re' true
Can we find an appropriate 'de dicto' paraphrase for any 'de re' proposition?
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
What Socrates could have been, and could have become, are different?
