Everyday language/ambiguity/Hintikka: the following expression is ambiguous:
(32) I see d
(33) (Ex) I see that (d = x)
That says the same as (31) if the information is visual or
(34) (Ex) (d = x & (Ey) I see that (x = y))
This is the most natural translation of (32).
Weaker: for the truth of (34) it is enough that my eyes simply rest on the object d. I do not need to recognize it as d.
