“…Conger proposes a world composed by twenty-five levels, enumerated as follows: "(1) energies, (2) electrons, (3) atoms, (4) molecules, (5) astronomical masses, or bodies, such as planetesimals, (6) solar systems, (7) star clusters, (8) galaxies, or great spiral nebulae, (9) possibly one or more groups of spiral nebulae -that is, one or more astronomical "universes." Then, in the biological realm, let us say (10) organic compounds, (11) infra-cellular organisms, such as Mathews calls micelle, (12) unicellular organisms, (13) multicellular organisms, (14) plant-and-animal groups, and then several levels exhibiting more complex types of social organization, such as (15) families or tribes, (16) nations or races, and, one might go on to say, (17) "The Great Society. " Once more, in the neuropsychological realm, one might add levels for (18) specialized cells, (19) nervous areas where the conduction is indiscriminate or reversible, (20) reflex arcs, and then doubtless for several different levels of higher neural synthesis, providing for (21) complex reflexes such as are apparently operative in perception and language-reactions, (22) instinctive-emotional complexes, (23) sentiments, (24) values, and, as a final term, (25) personalities" [17] .…”
