[Haskell-beginners] type question

I'm now following the book Programming in Haskel by Hutton.
IM now reading the chapter about types.

But I don't understand this : 

False :: Bool
True :: Bool 
¬  :: Bool  ---> Bool

So False  and True has the type Bool.
That's clear.

I find out that ¬ makes the opposite of True and False.
But why is it also the type Bool --> Bool
