Does it mean more or less than the following: Granted that, If I had ham, and I had eggs, I would have ham and eggs, having eggs screens off having ham from having ham and eggs? Screening off seems a very odd metaphor. Is it a term of art in logic?<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Also, a general problem I have with causality: My understanding of causality is that event A can cause event B if and only if A is independently known from B (an event cannot cause itself) AND occurs prior to B Now imagine two perfectly meshed gears, such that motion in one is instantly conveyed to the other. I turn gear A and gear B turns. Has the motion in A <i>caused</i> the turning of B or has my turning of A caused the motion of B? With the gears, this may just seem like a fussy “in the limit” sort of question, but there seem to be other phenomena where it’s worth asking. Does the discharge of potential along the ionized (?) path CAUSE the lightning?<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>I realize that the rest of you have spouses, dogs, cats, hobbies, and day jobs, but any off hand thoughts you have on these matters would be greatly appreciated. <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Nick <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>You can view "PM-2017-MethodologicalBehaviorismCausalChainsandCausalForks(1).pdf" at: <o:p></o:p></p><p class=MsoPlainText><a href="https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:a6e9c10b-06dc-4ea1-8ffa-d450df62489a">https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:a6e9c10b-06dc-4ea1-8ffa-d450df62489a</a><o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>________________<o:p></o:p></p><p class=MsoPlainText>Sent with Adobe Document Cloud.
