Does the head follow the heart in matters of truth?

[Amarok]

I doubt that any useful generality like that can be maintained vigorously

I don't really see them as useful 

. We often wish to be wrong, as well.

Wrongness is growth 

We might be suspiscious that our lover has a side piece

And if it's so is it not better to know? 

..or we might be convinced that some horrible thing x will happen

Horrible being a general term will inevitably happen 

.but no matter how hard we want to believe otherwise, we can't. Finding out that our suspicions were wrong or watching doomsday come and pass uneventfully produces relief, in those instances, not loss. Similarly, I think we could all think of times in our life when logic confirmed some intuition that amounted to misery rather than triumph.

 I agree with most of this.
