Illogical dear? (12)

I believe the answer is:

unreasonable

I believe this is a double definition.

'illogical' is the first definition.
(associated in meaning)

'dear?' is the second definition.
(I've seen this before)

(Other definitions for unreasonable that I've seen before include "dear?" , "Beyond acceptable limits" , "Irrational" , "Foolish" , "Immoderate" .)

I've seen this clue in The Telegraph.
