Banned, 'cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down ...

It is easy to go down into Hell;
Night and day, the gates of dark Death stand wide;
But to climb back again, to retrace one's steps to the upper air –
There's the rub, the task.
– Virgil, The Aeneid (Book VI)
