Well, I hesitate to respond only because the prospect of sitting down and having a beer with you is so appealing. But: I don't know that I would say that there are two ways to be embedded in time. I would say that there are different perspectives, equally true, and that they are related to each other. I mean its not like we have to say that either a wave has a frequency or a wavelength otherwise we are stating falsehood. Moreover the continuant occurrent distinction seems to be embedded even in fundamental physics where we acknowledge a wave-particle duality. The particle is something for which it makes sense to say that there is some thing that persists as time identically as time passes. The wave is different and other than for limited sets of boundary conditions, seems to be something not amenable to the same kinds of description. But you will be (perhaps) happy to know that I engage in debate and thought trying to probe and understand the distinction. And in other cases in BFO, recently on the subject of Spatial Regions, I have challenged the "truth" of the existence of these, at least as conceived in that ontology. (as far as I know there is no evidence for the existence of spatial regions as conceived in BFO). So suffice to say that the truth *does* concern me, even at the upper level. I suspect it concerns you to, based on the nature of the question. In David's case, we aren't anywhere near items about which there is controversy. David wants us to believe that the writers of foaf, having omitted a disjointness axiom between documents and people, have deliberately sanctioned that they can be equated, solely based on that omission, and immune from analysis of any text or discussion that has been written on the matter. -Alan > > Pat > > ------------------------------------------------------------ > IHMC (850)434 8903 or (650)494 3973 > 40 South Alcaniz St. (850)202 4416 office > Pensacola (850)202 4440 fax > FL 32502 (850)291 0667 mobile > phayesAT-SIGNihmc.us http://www.ihmc.us/users/phayes > > > > > >
