" Questions are always more subversive
than statements. For one thing, they are indirect. Whereas it should be crystal
clear what a statement is saying and where it is leading, a good question is not
so obvious, and where it leads to is hidden. For another thing, questions are
involving. Whereas a statement always has a “take it or leave it” quality, and we
may or may not be interested in what it tells us, there is no standing back from
a well-asked question. It invites us, challenges us or intrigues us to get into it
and follow it to see where it leads. In short, even a simple question can be a
soft form of subversion. "
