The contradiction of cladistics

Cladistics is the idea that we can acknowledge continuity instead of entities. The problem with this idea is that lineages are conflated. The end point of this acknowledgement is actually the same as acknowledging entities; the only difference being that the latter acknowledges both single and several, whereas the former only acknowledges several. This difference means that cladistics is contradictory between one and many, because one is, of course, true. .
