Suppose that insect wings developed primarily as thermoregulators and then were used for skimming and finally flying, evolving along the way. What would they be "for"? Or what is the skeleton "for"? For keeping one upright, protecting organs, storing calcium, making blood cells...?

Ontological questions are generally beside the point, hardly more than a form of harassment.

Every time a candidate came up from the base, that is with popular support, the Republican establishment went into high gear to destroy them with massive propaganda attack ads and so on. It was one after another, each one crazier than the last.

I think the use of language is a very important means by which this species, because of its biological nature, creates a kind of social space, to place itself in interactions with other people. It doesn't have much to do with communication in a narrow sense; that is, it doesn't involve transmission of information. There is much information transmitted but it is not the content of what is said that is transmitted.

Credible reports came through that Syria had used chemical weapons. Whether it's true actually is still open to question, but it's very probably true. At that point, what was at stake was what is called credibility. So if you read the political actors, political leadership, foreign policy commentary, they constantly point out accurately that US credibility was at stake, and we have to maintain US credibility. So therefore something had to be done to show you can't violate our orders.

There are very deep and restrictive principles that determine the nature of human language and are rooted in the specific character of the human mind

Technology can be used that way and it can also be used in other ways.
