The last theory is favored here. It implies that warfare has no grand functions, either sociobiological or ecological.

The spiritual aspects of his thought, however, have often been problematic, precisely because they seem to conflict with his more influential ideas. Although Collingwood's overtly theological and metaphysical writing can be safely confined to an early, perhaps even juvenile phase of his career, the spiritual dimension of some of his later work, including, for example, the famous doctrine of reenactment, has often been marginalized, repressed, or domesticated in order to preserve Collingwood's historical place in twentieth-century philosophy of history. This radical conflict continues to disrupt both the reception of Collingwood's ideas and attempts to contextualize them historically. However, if the spiritual and theological nature of Collingwood's thought is taken seriously, and not marginalized, it is hard to see his career as discrete stages of development. The problem of transcendent identity was a central concern for Collingwood throughout his career, and it unifies much of his thinking on divergent topics.
