Searle contends that consciousness is "causally reducible" to brain processes without being "ontologically reducible". And whilst this is acceptable ontologically, it is unacceptable, Badiou holds, philosophically. Agent causation is ontologically separate from event causation. That is, which is more ontologically fundamental the parts or their wholes. Monotheism is the belief in a single deity or God, who is ontologically independent. In Assyrian art, creatures ontologically between humans and divinities are also called "genie". Some philosophers have criticised rights as ontologically dubious entities. Secondary substances are thus ontologically dependent on substances. Ultimately, Sartre argues that because we can imagine, we are ontologically free. The universe and the divine are not ontologically equivalent. A secure non-contingent self-esteem springs from the belief that one is ontologically acceptable and accepted. It is thus ontologically distinct from Purushottam (also known as Parabrahman). It views Shiva and Vishnu as "complementary in their functions but ontologically identical". Kastner has criticized some other time-symmetric interpretations, including TSVF, as making ontologically inconsistent claims. Ontologically, tribalism is oriented around the valences of analogy, genealogy and mythology.
