In his essay «Terminus. The unconscious Godhead and the statute of being», Marco Della Luna not only explains Philosophy in its most intimate essence as a Sacred Science, but, most important, he demonstrates this pure essence when he states that "Philosophy arises from realizing that the conception of reality, i.e. the ontological conception, implicit in common sense, and presupposing a reality "made" in a certain way, does not stand up to a logical analysis, because it manifests contradictions" and furthermore when he states that one of the go-als of this new work of his is "the demonstration of total logical inconsistency of all the constructs elaborated in this way and the unsustainability of the common conception of being". Terminus is not an ordinary essay on Philosophy, as we can find on bookshelves, and it is definitely not a book for everybody, given its inevitable complexity: it is rather a book which teaches to see, discover and understand Philosophy in its most authentic light. A book that, and I say it without hesitation, can also help rewrite the concept of Ontology and the history of Philosophy itself.
