Tension: a relationship, not a substance

The standard

The perceptible polarity measures tension by the distance between two poles that hold each other, not by the strength of any single element.

Criteria

  • Two elements stand recognisably against each other
  • Neither of the two outweighs the other
  • The impression carries into the finish
  • The opposites feel held, not accidental

Distinction

Tension ≠ acidity: acidity is a measurable substance, tension a relationship into which it enters. Tension ≠ balance: balance is a resting equilibrium, whereas perceptible polarity describes an active pull between the poles.
