Different moralities must share some general features if they are to perform their functions of coordinating beings having particular kinds of motivations. Morality is a cultural construction in something like the way bridges are. There would be no bridges unless human beings used them to move across bodies of waters or depressions in the earth, but a good bridge cannot be designed according to whim, but rather according to what would adequately fulfill their function and the nature of the materials that are available for their construction.

Zhuangzi is especially insightful about the human pretension to know. The Zhuangzi tells a story about a frog who lives in caved-in well. Because he is the lord of this little world of his, king of the pollywogs, he is very proud of himself. But he doesn't know how small his world is until a turtle comes and tells him about the vastness of the sea. We human beings are like the frog, not realizing how little our worlds are.

The silver lining of Brexit and Trump is that it has undermined the perception that globalization is an unstoppable force, whether or not we think it is a good thing or a bad thing. There have always been losers and as well as winners in this process, and cultural minorities have been among the most vulnerable losers. Now that sizable numbers of people in the most advanced economies have made their grievances felt in a fashion that is hard to ignore.

Welcome to freakdom, Dave. It’ll be time to start a Web site soon, where you’ll type out everything in one huge paragraph.

Learning what it is to be among other human beings includes learning that they can be different from us as well as similar. We imagine what it would be like to experience the world differently from their locations, nor our own. We might still use analogies to understand others, but analogies point to similarities that co-exist with differences. Similar in some respects is consistent with different in other respects.

You see, Frank found out the hard way that the dark things lurking in the night don’t haunt old houses or abandoned ships. They haunt minds.

The demonization of Islam and immigrants shows that perception of difference remains one of our biggest problems, and maybe always will be for a species that began in small groups competing with other groups for resources. These apparently competing forces for sameness and difference sometimes even seem to be mutually reinforcing. The homogenizing force of globalization tends to make many people feel they are on the losing side, economically and culturally, and it is they who are most easily turned against those "others" who are demonized by demagogues.
