  • RE: DOES HORIZONTAL TRANSMISSION AMEND OUR CONCEPT OF LIVING SPECIES?
    • Arturo Tozzi, Adjunct Assistant Professor, University of North Texas

    Demarcation among objects and things is somewhat arbitrary, because our mind tends to exclude the continuity among hidden or unknown structures of the world. We are used to draw lines of separation among things that we judge different, arbitrarily excluding or including issues in our description, to achieve positive demarcations that allow a pragmatic treatment of the world based on regularity and uniformity (Popkin and Maia Neto, 2007; Autrecourt, 1340). In touch with set theory, observers tend to spatially and temporally split the set of the entire world in different, arbitrary, fictious subsets that could not really stand for different objects or events. The same scientific concept of “observable” lies on the choice of variables in peculiar experimental settings: scientists, putting aside most of the variables, focus their efforts on a few features. For example, elementary particles are fully defined just in terms of three experimental observables, i.e., charge, spin and mass, letting aside, for practical purposes, less “useful” features. There’s a plenty of boundaries in math, physics and biology. In these disciplines, the concept of boundary is grounded on the presence of internal and external surfaces. This concept seems straightforward in math, and in particular in topology, where we are in front of planes split into an “interior” region bounded by curves and an “exterior” one, containing all of the nearby and far away exterior points.
