It doesn't seem at all problematic for Aquinas to suppose that there could be ghosts that could interpenetrate.<br /><br />We never measure a single point position, though. Our particle detectors are not that precise. What we measure is whether the particle is within some region of non-zero volume. Perhaps, though, you were referring to something like Bohm's theory.Alexander R Prusshttps://www.blogger.com/profile/05989277655934827117noreply@blogger.comtag:blogger.com,1999:blog-3891434218564545511.post-87486651140014244992016-04-18T19:03:42.429-05:002016-04-18T19:03:42.429-05:00I think you reveal a bind for Aquinas' substan...I think you reveal a bind for Aquinas' substance concept here, if that matters.<br /><br />Because physics says that such particle waveforms can and generally do overlap, overlapping composition in space is then genuine. So one can use this to show that a given region contains more than one substance, so that there is no reason not to allow substances like a body to have composition and contain other substances. <br /><br />Alternatively, the waveform and the extension are not genuine, and only the just-measured single point position of the particle is real.<br />Williamhttps://www.blogger.com/profile/12533263841520213358noreply@blogger.com
