Hennig's (the cladistic) idea of "a single true tree of life" is actually a paradox - the subjective aspect of Russell's paradox

Hennig's (the cladistic) idea of "a single true tree of life" is actually a paradox - the subjective aspect of Russell's paradox. Such thing can't be found without paradoxical contradiction per definition, because classification is orthogonal. The idea is thus a practical void. It is just the paradoxically contradictory end point for realism.
