Terms

What this domain tests

The term as the unit of meaning, kinds of terms, connotation and denotation, and the distribution of terms - the skill on which the whole syllogism unit depends.

Kinds of terms

  • Singular (names one thing: "Karnataka"), general ("river"), collective ("team" - predicable of the group, not of each member).
  • Concrete (refers to an object: "book"), abstract (refers to a quality: "courage").
  • Positive ("honest") versus negative ("dishonest").
  • Connotative terms mean an attribute and denote the objects having it ("poet"); non-connotative terms merely denote ("Mysuru").
  • Denotation = the class a term applies to; connotation = the attributes fixing membership. Increasing connotation normally narrows denotation.

Distribution

A term is distributed when it stands for all of its class.

  • A: subject distributed, predicate undistributed.
  • E: both distributed.
  • I: neither distributed.
  • O: predicate distributed, subject undistributed.

Worked example

"All poets are imaginative." The subject "poets" is distributed - something is said of every poet. The predicate "imaginative" is undistributed, because nothing is claimed about all imaginative people. So the conversion "All imaginative people are poets" is invalid; it distributes a term the premise left undistributed.

Traps that cost marks

Treating "collective" as a synonym for "general"; forgetting that in O propositions it is the predicate that is distributed; assuming negative terms are automatically undistributed; overlooking that singular terms behave as distributed subjects.
