The title inspired by Bertrand Russell’s and Alfred North Whitehead’s seminal "Principia Mathematica", the philosophical enterprise "Principia Ontologia" can be described as a genealogically-cognizant, structurally-conscious, and phenomenologically-competent fundamental ontological inquiry. It is designed to answer the question Martin Heidegger’s 1927 tour de force "Being and Time" intended to but—owing to various reasons—fall short of answering. The question—standing at the core of Heideggerian oeuvre, both before and after "die Kehre"—the project is keen on catalyzing an acumen into is concerned with the truth of Being and its meaning. The latter is something enterprise metaphorically describes—à la Cicero’s ethical writings—as a "summum bonum" of ontological investigation. An investigation that began in fifth-century BCE Greece where sagacious pre-Socratic philosophers—such as Parmenides and Heraclitus—summoned enough courage and open-mindedness to ask "What is Being?". Thanks to their bravery, pre-Socratic thinkers commenced the precise inquiry the tradition great British process philosopher safely characterized as footnotes to Plato couldn’t help but forget, Heidegger revived, and principia ontologia intends to take to a higher, more inclusive and encompassing level. Appreciating the fact that, as Heidegger underscored, "the essence of Being is never conclusively sayable"—an acumen that, in lieu of an end, is exclusively the beginning of authentically fundamental ontological inquiry—the enterprise employs different terms in the interest of pointing towards the same summum bonum that principia ontologia, besides "Being", also describes as Ursprung; Urphanomen; Primordial Clearing/Ground/Unconcealment, not to mention other terms, all meant to encourage advancement towards the truth the Messkirch-born ontologist—in his essay, titled "The Origin of the Work of Art"—disclosed as "unconcealment of Beings (Being)", where "Beings can be as beings only if they stand within and stand out within what is cleared in this clearing. Only this clearing grants and guarantees to us humans a passage to those beings that we ourselves are not, and access to the being that we ourselves are. Thanks to this clearing, beings are unconcealed" (Heidegger, M. 1929)."
From the outset, "Sein und Zeit" declares that the question concerning ontological summum bonum, "today been forgotten", nonetheless, the "question we are touching upon is not just a n y question. It is one which provided a stimulus for the researches of Plato and Aristotle, only to subside from then on as a theme for actual investigation" (Heidegger, M. 1927). Rather than just "any" inquiry, the foregoing, by account of Heidegger, has begun "the ek-sistence of historical man" who through "asking: what are beings?" facilitated disclosure of Primordial Aletheia "for the first time". In light of the latter's immense philosophical significance, according to principia ontologia, only deepened fundamental ontological inquiry that marries original contemplation, investigation, and research with the meticulous, careful, and patient integration of numerous invaluable breakthroughs of pre-modern, modern, and post-modern epochs can facilitate progress towards the truth of Being. Exclusively the enterprise that preserves noteworthy advancements, acumens, and realizations while simultaneously negating numerous partial viewpoints, inaccurate conclusions, and misguided observations of each major epoch can defend itself from myriad enemies of ontological advancement. Anything less than the preceding will inescapably yield to what the German thinker delineated as "the path of metaphysics" where oblivion of Being reigns supreme, permitting throngs of beings to obscure the very unconcealment that permits these beings to arise in the first place. Fortunately, principia ontologia is exactly such enterprise that, on grounds of its chosen modus operandi, can "supersede", à la Hegel, its predecessors, including—the greatest influence upon the project—Heideggerian fundamental ontology, the terminology of which the enterprise utilizes in its every undertaking, ranging from deepening Heidegger’s investigation of death to rescuing Heideggerian-animal ontology from erroneous criticisms to unveiling the genealogical roots, structural make-up, and farther reaches of an uncommon entity whose essence lies in its existence to disclosing hidden patterns governing phenomena that inescapably influence Being-in-the-world, not to mention to other missions genealogically-conscious project is keen on fulfilling on its way to an insight into the meaning of Being.
Besides the Messkirch-born ontologist’s body of work acting as an indispensable substratum, from which principia ontologia intends to facilitate an acumen into the truth of Being and its meaning, the enterprise has been profoundly influenced by Husserlian phenomenology, Derridean deconstruction, and Wilber’s integral meta-theory, to say nothing of a host of other Western intellectuals the project does not discuss as explicitly, comprehensively, and intensely as Heidegger, Husserl, Derrida, and Wilber, yet whose shadow falls on the text's every page. Via the careful utilization of selected methodology, namely, "principal ontological triad", materialized in the form of phenomenology, structuralism, and genealogy, the project will not only provide a rigorous analysis of its forerunners’ contributions—tapping into their strengths while evading their weaknesses—but more importantly, principia ontologia, if successful, will save fundamental ontological inquiry as a whole in the post-post modern epoch, where in spite of tradition’s invaluable accomplishments, the question of Being has been left unanswered and, more often than not, forgotten, or worse still, abandoned as unanswerable at best or nonsensical at worst. By unconcealing that "If the power of the intellect in the field of inquiry into the nothing and into Being is thus shattered, then the destiny of the reign of “logic” in philosophy is thereby decided. The idea of “logic” itself disintegrates in the turbulence of a more original questioning". (Heidegger, M. 1929), the Messkirch-born ontologist—in "What Is Metaphysics?"—was able to achieve the ostensibly impossible mission of catalyzing an insight into Nothing. Likewise, if the reign of numerous valid but incomplete perspectives is permitted to disintegrate in the turbulence of a more original philosophizing, while as Schopenhauer accentuated, the tendency of taking the limits of one’s vision as the limits of the world is overcome, akin to Heidegger attaining what previously was deemed unattainable, principia ontologia can also access what each and every genealogically, phenomenologically, and structurally incompetent standpoint, theory, and methodology—across pre-modern, modern, and post-modern epochs—felt obliged to give upon as inaccessible.
