10. Modality / B. Possibility / 8. Conditionals / f. Pragmatics of conditionals

9723	Sentences with 'if' are only conditionals if they can read as A-implies-B [Enderton]
	Full Idea: Not all sentences using 'if' are conditionals. Consider 'if you want a banana, there is one in the kitchen'. The rough test is that a conditional can be rewritten as 'that A implies that B'.
	From: Herbert B. Enderton (A Mathematical Introduction to Logic (2nd) [2001], 1.6.4)

10. Modality / E. Possible worlds / 3. Transworld Objects / e. Possible Objects

15142	Our ability to count objects across possibilities favours the Barcan formulas [Williamson]
	Full Idea: Consideration of our ability to count objects across possibilities strongly favour both the Barcan formula and its converse.
	From: Timothy Williamson (Truthmakers and Converse Barcan Formula [1999], §3)
	A reaction: I'm not sure that I can understand counting objects across possibilities. The objects themselves are possibilia, and possibilia seem to include unknowns. The unexpected is highly possible.
