Nominalism, Species, History

One of the shortcomings of Nominalism, i. e. Atomist Semantics, is its inadequacy to organisms.  For example, that "forest" signifies a multiplicity of trees, while "tree" does not signify a multiplicity of leaves, branches, etc., is arbitrary.  Furthermore, it cannot represent growth, e. g. the "Jones family" before the birth of the second child not only means something different afterwards, Nominalism cannot connect the two meanings.  So, there is no adequate Nominalist objection to the proposition 'The human species is governed by a principle of Diversification', i. e. the history of the species cannot be reduced to an account of all the individual humans in a time-span.
