A couple of years ago, Neal Whitman and Mark Liberman scrutinized a claim by James J. Kilpatrick. From Mark’s summary, here:
James Kilpatrick complained in print about the “horrid” headline “Mass Transit Not An Option for All Drivers”, on the grounds that “if mass transit is not an option for ‘all’ drivers, it cannot be an option for even one driver”. He added, “Even a little ambiguity is a dangerous thing. The problem with this Horrid Example is that it creates a nanosecond of uncertainty.”
Neal Whitman and I ignored the “nanosecond of uncertainty” business, since a literal application of this idea would put pretty much all of the English language off limits.
Mark and Neal focused instead on Kilpatrick’s treatment of negation and quantification (and Jan Freeman joined in with a discussion of another example from this point of view). Here I’m going to go a bit further with the “nanosecond of uncertainty” matter and the dangers of “even a little ambiguity”.
