Fernan: the Value of the Intuition

Hereby it is presented a new set theory (generalized as the so-called system theory, fully respectful with the dictates of intuition (including the existence and numerability of the universal set, of which all beings are elements) and capable to overcome all the logical difficulties that forced logicians in last century to accept never desired axioms for avoiding contradictions. The somewhat philosophical nature of the essay, imposed by the need to distinghish between concepts before not sufficiently clear, if not confused, and now denoted with distinct names (some neologisms), such as entema, concept, reflexo, set, system, aente, uente…, should not prevent the appreciation of its mathematical significance.
