Man is a creature of hope and invention, both of which belie the idea that things cannot be changed.
The Image is more than an idea. It is a vortex or cluster of fused ideas and is endowed with energy.
The walls, the bars, the guns and the guards can never encircle or hold down the idea of the people.
If it's a good idea, go ahead and do it. It's much easier to apologize than it is to get permission.
