As others, I am very much enjoying the early going in this dialogue. The organizers are to be commended. I would wish to second the concern raised by one of Dr. Boydell's recent postings that warns us against universalism.
Land is only what people see in it and make of it.
It is not for us to determine what that should be. When we advance Lockean prescriptions we are advancing a particular world view that, while perhaps common in one part of the world, need not be accepted in others.
