Res Publica Rationis is the Commonwealth Of Reason. It is an effort to demonstrate that people can live within Earth's resource budget, can reclaim the urban centers that have been left to decay, and can live responsibly and co-operatively.
Recent economic developments are demonstrating that we cannot continue to live as if Earth were an eternal wellspring of resources. There is a limit, and we reached and passed it long ago. Res Publica Rationis began as the work of a single person. If more join the effort, we can have comfortable, if not opulent, lives again.
