  Hofweber explains that the inferential role reading serves an important function.  It enables us the easy expression of partial information. For example, I might not recall a name or unique description of Fred’s favorite detective, but if I want express the partial information I have, I can do this by saying “Fred admires some detective.”.  Now, on the domain-conditions reading, what I express is false, and so I have misinformed my audience.  What we need, to achieve the desired end, is a reading for ‘there is an F’ which validates existential generalization, regardless of whether the names occurring in the premise refer to an entity.  This is what the inferential role reading provides.  Thus, we say “Fred admires some detective — yes, it’s Sherlock Holmes!”
