For some things an abstract issue is completely clarified by thinking about a well-chosen concrete example, for which the answer appears obvious. For me, the answer appears obvious in the case of this example, and abstracting from this example is one way to understand the general situation. For many other people this example may be no clearer than the general question, in which case you're absolutely right. | |
