|Sortal, philosophy: Sortal is an expression for a concept that summarizes several countable objects on the basis of common characteristics. ( "varieties/sorts"). The use of the term "sortal" is intended to avoid, among other things, the use of terms such as categories or universals that would require a variety of additional assumptions. See also order, generality, generalization, general terms, identity, identity conditions, criteria, change, classes, categories, universals, conceptual realism, mass terms._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments.|

Sortal/Aristotle/Tugendhat: E.g. "chair" distinguished through function -> "bottom-up": we ask how singular term must function - sortal: allows to decide what belongs to it and what does not - no temporal, only spatial limits - (>continuant) - life phases of an object are not regarded as parts.
Sortal/Tugendhat: allows new type of temporal-spatial identification - we should not presuppose perceptual object - then identification by distinguishing space-time locations - (Specification).
Sortal:. Not just imagination - Sortal predicates: presuppose a specific configuration of spatial or temporal extended - e.g. "the same cat" - conversely: sortal predicate only explainable through space locations together with equal signs._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
