Constructing Social Reality

Here is a link to a Colin McGinn review of John Searle's new book Making the Social World. I think some of McGinn's criticisms may miss the mark, though I haven't actually read the book yet. I have read his earlier The Construction of Social Reality), in which he develops the useful observation, not that reality itself is socially constructed, but that human institutions (money, universities, marriage...) often are pure products of our aggregate intentions. For example, money is a really existing thing, and an important force in the world, but can only exist because and as long as we collectively behave as though little scraps of paper with ink on them have exchange value.
