Easy's existential theories are put to the test when the deputy police commissioner asks him to conduct a quiet investigation into the death of Nola Payne -- a young black woman known as Li'l Scarlet for her flaming red hair -- who was last seen alive rescuing a white man from a gang of rampaging rioters.
The rare exception is Alphonso Lingis, author of Excesses (1983), Libido: The French Existential Theories (1985), and The Community of Those Who Have Nothing in Common (1994).
This has implications for existential social theory (see the section on Sartre: Existentialism and Marxism below).
Depersonalization as a characteristic of psychological disorder is a prominent theme in existential and neoanalytic theories of personality.
The principle disadvantage of an entailment account as compared with a quantifier account is that it fails to provide a neutral platform for assessing the ontological costs of theories: disagreements over ontology will often reappear as disagreements over the existential entailments of a theory.
The fact that a worker in India now can write lines of computer code for I.B.M. does not pose an existential threat to economic theory.

For a second thing, parties to an ontological dispute will often disagree over the existential entailments of a theory (see §2.2 below).
Is there room to deny that existential consequences of a theory, as given by sentences of first-order logic with the existential quantifier, do not amount to ontological commitments of the theory?
And, even when translated into a formal language, such as the language of first-order predicate logic, different ontological standpoints may disagree as to the existential presuppositions of the theory.
