Flexibility in Ceteris Paribus Reasoning
Ceteris Paribus clauses in reasoning are used to allow for defeaters of norms, rules or laws, such as in von Wright [5]’s example “I prefer my raincoat over my umbrella, everything else being equal”. In [3, 4], a logical analysis is offered in which sets of formulas Γ , embedded in modal operators, provide necessary and sufficient conditions for things to be equal in ceteris paribus clauses. Fo...
متن کاملCeteris Paribus Laws: Genericity and Natural Kinds
Ceteris Paribus (cp-)laws may be said to hold only “other things equal,” signaling that their truth is compatible with a range of exceptions. Several theorists have suggested that because of this feature, these generalizations are semantically defective. Against these concerns, I argue that cp-laws are often stated using a special kind of construction found in natural language, generics, which,...
متن کاملCeteris Paribus - Laws : A Naturalistic Account
An otherwise law-like generalisation hedged by a ceteris paribus (CP) clause qualifies as a law of nature, if the CP clause can be substituted with a set of conditions derived from the multivariate regression model used to interpret the empirical data in support of the generalisation. Three studies in human biology that use regression analysis are surveyed, showing that standard objections to c...
متن کاملCeteris Paribus Conditionals and Comparative Normalcy
Our understanding of subjunctive conditionals has been greatly enhanced through the use of possible world semantics and, more precisely, by the idea that they involve variably strict quantification over possible worlds. I propose to extend this treatment to ceteris paribus conditionals – that is, conditionals that incorporate a ceteris paribus or ‘other things being equal’ clause. Although such...
متن کاملAn Empirical Investigation of Ceteris Paribus Learnability
Eliciting user preferences constitutes a major step towards developing recommender systems and decision support tools. Assuming that preferences are ceteris paribus allows for their concise representation as Conditional Preference Networks (CP-nets). This work presents the first empirical investigation of an algorithm for reliably and efficiently learning CP-nets in a manner that is minimally i...
