Pluralism (плюрализм) is the last axiom among the TORI axioms set  Pluralism, postulated as compulsory for the scientific concept, declares, that mutually-contradicted concepts may coexist in science, but specifies their subordination:
If two concepts satisfying first 5 TORI axioms, have some common range of validity, then, in this range, the simplest of them has priority.
Concepts, that use complicated formalism to describe simple the simple phenomena have low priority, and the simple concepts, that are applicable to the case, should be considered first. The ideas of pluralism are not new, they are discussed and applied during centuries; some links are suggesed at http://en.wikipedia.org/wiki/Occam's_razor
The Pluralism as idea of simplicity, had been used to guess the asymptotic behaviour of the natural tetration at $\pm \mathrm i \infty$  and some other concepts listed as examples in article Place of science in the human knowledge.
