“The commons” is composed of our shared assets: the earth’s atmosphere, oceans, and water-cycle; basic scientific knowledge (which cannot be patented); the heritage of human creativity, including folklore and the whole works of Plato, Shakespeare and every other long-dead author; the Internet, viewed a single structure (although its components are privately owned); public law; physical public spaces such as parks and plazas; the broadcast spectrum; and even cultural norms and habits. Some of us believe that protecting and enhancing the commons is a central political task of the 21st century. For different flavors of that argument, see, for example, OnTheCommons, The Tomales Bay Institute, and Lin Ostrom’s workshop at Indiana.
I have suggested that enhancing the commons might be a strategy for increasing equality. If that strategy belonged to the radical left, I would not hesitate to embrace it. However, I don’t think that it has much to do with traditional leftist thought. It is worthwhile to distinguish the theory of the commons from Marxism, just for the sake of clarity. I see several fundamental points of difference.
