Qualitative predicates, like green, can be assessed without knowing the spatial or temporal relation of x to a particular time, place or event. Locational predicates, like grue, cannot be assessed without knowing the spatial or temporal relation of x to a particular time, place or event, in this case whether x is being observed before or after ...
1860 engraving depicting the performing horse Marocco. A significant portion of medieval technical literature consists of treatises on veterinary care. [S 11] Arab and Muslim scholars made notable contributions to the knowledge of equine medicine, education, [5] and training, in part due to the contributions of the translator Ibn Akhî Hizâm, who wrote around 895, [6] and Ibn al-Awam, who ...
First-order logic—also called predicate logic, predicate calculus, quantificational logic—is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science. First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables.
Most predicates attribute properties to their subjects, but the redundancy theory denies that the predicate is true does so. Instead, it treats the predicate is true as empty, adding nothing to an assertion except to convert its use to its mention. That is, the predicate "___is true" merely asserts the proposition contained in the sentential ...
The predicate calculus goes a step further than the propositional calculus to an "analysis of the inner structure of propositions" [4] It breaks a simple sentence down into two parts (i) its subject (the object (singular or plural) of discourse) and (ii) a predicate (a verb or possibly verb-clause that asserts a quality or attribute of the object(s)).
The first thing to extract from this passage is the fact that Peirce's Categories, or "Predicaments", are predicates of predicates. Meaningful predicates have both extension and intension , so predicates of predicates get their meanings from at least two sources of information, namely, the classes of relations and the qualities of qualities to ...
A sentence can be viewed as expressing a proposition, something that must be true or false. The restriction of having no free variables is needed to make sure that sentences can have concrete, fixed truth values : as the free variables of a (general) formula can range over several values, the truth value of such a formula may vary.
Control predicates semantically select their arguments, as stated above. Raising predicates, in contrast, do not semantically select (at least) one of their dependents. The contrast is evident with the so-called raising-to-object verbs (=ECM-verbs) such as believe, expect, want, and prove. Compare the following a- and b-sentences: a.
