Two-sided viewpoint

A two-sided viewpoint is a viewpoint applied to an object o which takes into account both poles of a given duality. A two-sided viewpoint is opposed to a one-sided viewpoint, where only one pole of a duality is considered. On the other hand, in the two-sided viewpoint, both poles of a duality are taken into account and applied to a given object o. Thus, if the poles A and Ā of a matrix of concepts are taken into account, it will be a two-sided viewpoint.

Matrix of concepts

The structure of a matrix of concepts

The matrix of concepts is a structure that includes six concepts, which is suitable for modeling many common concepts, such as: courage, recklessness, irresolution, eclecticism, superficiality, clemency, instability, selfishness, objectivity, frankness, brusqueness, altruism, etc. Of the six concepts in the matrix:

  • two are neutral: A0 and Ā0
  • two are positive: A+ and Ā+
  • two are negative: A and Ā

These six concepts constitute the canonical poles of the matrix.

The six concepts of the matrix are in particular relationships with each other. Thus:

  • the neutral concepts A0 and Ā0 are dual
  • the positive concept A+ and the negative concept Ā are opposite (or contrary); similarly, the negative concept A and the positive concept Ā+ are opposite (or contrary)
  • the positive concepts A+ and Ā+ are complementary
  • lastly, the negative concepts A and Ā are extreme opposites
An instance of matrix of concepts

In the above instance of matrix of concepts:

  • the propensity to take risks and the propensity to avoid risks are dual
  • audacity and cowardice are contrary, opposite; in the same way, temerity and prudence are contrary, opposite
  • audacity and prudence are complementary
  • temerity and cowardice are extreme opposites

Moreover, the three concepts located on the left of the matrix constitute a half-matrix: it is the half-matrix associated with the pole A. In the same way, the three concepts located on the right of the matrix constitute the half-matrix associated to the pole Ā.
