Say I am walking down a street in a large city and come across a homeless person on the sidewalk, and I ask myself if that could have been my fate. If I think that I could have been that person—except for different circumstances—then we share a common humanity. Our differences are basically social. If I say that I would never become such a person, then I take our social differences—class, race, religion, and so on—as essential. We have nothing in common.

In memory of W. Barnett Pearce
A commonsense way of thinking about disagreements is that they arise when people have opposing opinions, they have an invested interest in maintaining them, and they have to make a decision. In this framework, our positions are seen as things we own—as our property.

Libertarians come in different stripes, and the differences largely depend on their foundation. Some have their origin in the peculiar Anglo-American tradition of grounding liberty in property. Some others see liberty as a civic right guaranteed by the Constitution.
