Consequently, it is knowable >_a priori_. Nope. I can step in front of a bus and *not* get run over (it's a stationary bus :-) Or does a stationary bus not have "bus-hood"? Or does the concept of "stepping in front of" exclude stationary vehicles? Etc, etc, for all other cases of not getting run over ... So it looks more like: IF I step in front of a bus, *and* it is moving sufficiently fast, *and* the driver fails to avoid me, *and* I fail to jump back (having suddenly perceived the bus), *and* ... (insert more conditions as required) ... THEN there is a *high probability* that I wil be run over (I don't think you can practically specify sufficient conditions for this to become a certainty!) -- =============================================================================== Dave | dsg@imp.co.uk | +44 753 516599 | "C^i tio ne estas .subskribo" ===============================================================================
