Atom, Cell, Socialism

In his dissertation, ostensibly a comparison of the Atomism of Democritus with that of Lucretius, Marx introduces Dialectical Atomism as an alternative to the standard Mechanical Atomism.  This precursor of Dialectical Materialism thus reflects the predominance in the era of Newtonian Physics.  Now, decades later, incorporating more recent discoveries in Biology in his attempt at a Dialectical Materialist Science, Engels recognizes that the basic unit of life is the Cell.  However, he offers no derivation of the Cell from the Atom, other than to briefly note its relatively late emergence into Nature.  Absent such a methodical derivation, insofar as Socialism is a Biological formation, i. e. is a condition of the Human species, it is not a product of Dialectical Materialism.
