For 10 points, identify these verbal assurances of some future deed or obligation.  
"Principle F" is part of a non-conventionalist theory of these acts known as the "expectation view," proposed in the early 1990s by Tim Scanlon. A so-called "Complicated Way" of defining this sort of act involves nine separate conditions which must hold, of which the first reads: "Normal input and output conditions obtain". Along with forgiveness, this type of action is a remedy for the twofold "darkness of human affairs" according to Hannah Arendt's The Human Condition. Hume's Treatise of Human Nature claims that the purported force of this sort of act is as magical as "transubstantiation, or holy orders." The claim that early man was too forgetful to engage in this activity is made in the Second Essay of Friedrich Nietzsche's On the Genealogy of Morals, (*) which opens by explaining how "to breed an animal that is entitled to" do this sort of act. To determine the structure of illocutionary acts in general, John Searle analyzed the "sincere" and "insincere" type of these in his 1969 book Speech Acts, noting that insincere ones still make the speaker S "responsible for intending to do" a spoken-about action A.
