A specialization of #$AbstractInformationalThing. Each instance of #$Microtheory is an abstract informational thing that represents a context in Cyc. Each microtheory (or 'mt') serves to group a set of assertions together that share some common assumptions; the assertions in an mt constitute the content of that mt. Note that each assertion in the Cyc knowledge base must be explicitly stated to be true in at least one microtheory. Assertions stated to be true in one mt will also be true (by inference) in more specialized mts that depend on the content of that mt. For example, if something is true in the #$HumanSocialLifeMt (q.v.), then it should by default be true in the more specialized #$UnitedStatesSocialLifeMt (q.v.). Specialized microtheories are related to the more general microtheories on which they depend by the predicate #$genlMt (q.v.). Note that every query is made in some mt, and the answer one gets to a query depends on the mt in which it is asked, since the only assertions which can be used to answer a query in an mt are those explicitly stated to be true in that mt, or in some more general mt. See also the predicate #$ist, which is used to relate an assertion to the microtheories in which it is true.#$MicrotheoryType types of microtheory

A specialization of #$Microtheory. Each instance MT of #$FictionalOrMythologicalContext is a microtheory for which the following property holds: there is at least one assertion ASSERT which holds in MT (so that (#$ist MT ASSERT) is true), but which is widely believed to be false. Although microtheories with this property would appear to have limited utility, they can be useful in reasoning about the content of fictional works or the content of certain belief systems.

A #$MicrotheoryType. Each instance of #$HypotheticalContext consist of assertions that are posited strictly for the purpose of exploring their consequences, without alleging their actual truth. A hypothetical context can be used to analyze hypothetical outcomes of actions or to examine the hypothetical consequences of assuming some theory to be true.

direct specialization of: #$Microtheory
A collection of microtheories; a subcollection of #$SupposedToBeMicrotheory. Each instance of the collection #$Obligation is a microtheory which contains assertions describing what some agent (the #$obligatedAgent) is obliged to do, or make true, for one or more other agents, possibly including society in general. An obligation is the most general case of some agent owing something to another. Obligations may be undertaken in conjunction with various kinds of #$Agreements. Unlike an agreement, however, an obligation need not have a second known party (though some do). An obligation can exist and be understood without identifying another particular agent as the `holder' of the obligation -- and that may be true, even if the beneficiary (#$obligationOwedTo) can be identified. For example, assuming that parents have an obligation to care for their children, it is not clear with whom a parent has `agreed' to take care of his or her child. Some common ways to incur an obligation are through social transactions (e.g., family duties, friendship, favors) or through financial transactions (e.g., a #$PaymentObligation). In addition, obligations may be imposed on those who are subject to one or more instances of #$CodeOfConduct, e.g., #$LegalCode-ModernUnitedStates, #$SportsRulesOf-BoxingSportsEvent, #$OfficeCodeOfConductMt.#$Estimate estimations **COMMENT NOT REVIEWED** **GAFs NOT REVIEWED**

For example, IBM's estimate on January 1, 1992, of fourth quarter earnings for 1991. This concept encompasses the common meaning of `estimate' and also `guess'. This contrasts with beliefs which are derived primarily from rigorous or reliable reasoning, direct observation, or consultation of authoritative sources. This also contrasts with intentional lies and works of fiction, which are not #$Estimates.#$Story stories **COMMENT NOT REVIEWED** **GAFs NOT REVIEWED**

Vocabulary For Stating Relationships Between Microtheories
#$genlMt genl mt
This predicate relates a more specific microtheory to a more general one, where the former constitutes a specialization with respect to the latter. More precisely: (#$genlMt SPEC-MT GENL-MT) means that any assertion that is true in GENL-MT is also true in SPEC-MT. Thus a query posed in SPEC-MT has access to all of the assertions asserted in GENL-MT. (The consequences of this are far-reaching since #$genlMt is transitive.) One particular microtheory, the #$BaseKB, is in the unique position of being a generalization (via #$genlMt) of every microtheory. (Note that, for technical reasons, all #$genlMt assertions should be made in the #$BaseKB.)#$contradictoryMt contradictory mt
