This paper compares the two known logical forms of hierarchy, both of which have been used in models of natural phenomena, including the biological. I contrast their general properties, internal formal relations, modes of growth (emergence) in applications to the natural world, criteria for applying them, the complexities that they embody, their dynamical relations in applied models, and their informational relations and semiotic aspects.

It is clear that natural entities can be preserved – they can be preserved because they can be harmed or destroyed, or in various other ways adversely affected. I argue that in light of the rise of scientism and other forms of philistinism, the political, religious, mythic, personal and historical meanings that people find in those entities can also be preserved. Against those who impugn disciplines such as fine arts, philosophy and sociology, I contend that this sort of preservation requires (...) the efforts of those whose work exemplifies the core values of the arts, the humanities and the qualitative social sciences.
