Abstract
In the hesychast controversy was disputed the hypothesis that the access to the ultimate reality would be only an act mediated by the hierarchy of the beings. That is why there appears the syntagm ‘uncreated energies’. Gregory Palamas sustained that experimentality is decisive, the truth criterion being provided by the ‘appeal to experience’. The hesychasm differs from other Cristian spiritual practices by the fact that it emphasizes the experience in the shape of the experiment: it`s supposed the existence of a method, of a verifiability criterion, and validation: henceforth the interest for the Personal Ultimate Reality or, in the hesychast language, for the uncreated energies. The hesychast meaning for philosophizing implies the making of a constant ‘appeal to experience’ and not producing theoretical speculations on God. This because of the decisive role gave to senses by the hesychast anthropology.
