Opposition relationship

An opposition (or contrary) relationship exists within a matrix of concepts, between:

  • on the one hand the concepts A+ and Ā-
  • and on the other hand, the concepts A- and Ā+


For example, the concept of courage is the opposite of the concept of cowardice. And similarly, the concept of temerity is the opposite of the concept of prudence.
