And the dream that our mind had sketched in haste
Shall others continue, but never complete.
For none upon earth can achieve his scheme;
The best as the worst are futile here:
We wake at the self-same point of the dream -
All is here begun, and finished elsewhere. [ Victor Hugo ]

To seek to change opinions by laws is worse than futile. [ Buckle ]

One futile person, that maketh it his glory to tell, will do more hurt than many that know it their duty to conceal. [ Bacon ]
