logical gap between Tao level 0-1 and Tao level 2

In the subdivision of hierarchical levels the different context classes of systems were divided according to their extension:

In this division level n+1 has an extension of description/application greater than the level n, and includes all lower sublevels n-1 etc.

With the introduction of logical levels it is necessary to separate the hierarchical levels from those that are also logical/hierarchical.

While the level 1 - chemical and level 0 - physical are on the same logical level, level 3 - cell-biology, has a higher logical level, as well as a greater extension. The main reason is that from level 2 to 3 was born a unique emergent behavior , that is life.

In the living systems theory proposed in 1978 by James Grier Miller are highlighted at least 8 levels of hierarchy from level 2 to 4:

 

The transition from one level to another, from the physical to biological to social, follows the evolution of life on earth:

(here the authors are very optimistic, and assume that there will be a far future post-technological and not KaliYuga)
