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

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.
