I do indeed mean "faith" in the sense of "belief in the absence of
evidence", i.e., "drawing a line on your map without having seen
something that corresponds to the line, perhaps because you haven't
visited that part of the territory yet". Not necessarily "faith" as
"belief contrary to evidence", i.e., "drawing a line on your map that
contradicts something you actually saw". Either way you end up with a
lousy map.

In any case, you seem to have missed the point of my objection:
assigning a high probability to love is a type error.
