The form of this thesis is that of a long philosophical essay. It crosses the circuit of the ages of metaphysical thought, having as its nuclear question what is defined by the concept of metaplace. The term metaplace, present in the title of the work, refers to a labyrinthine structure, or rather, to the shape of a palindrome made not with letters, but with signs and ideas whose writing and articulation invite the crossing of thought at the heart of each metaphysical era. The writing developed in this essay tours through speculative turns and is inspired by the Achilles shield, an artifact and, also, a kind of metaplace, whose manufacture by the hands of the god Hephaestus, in the Iliad, inaugurates in the West an image-conception of world. The thesis draws on the similarity of the hephetic shield, shaped to think of forces that have prevailed metaphysically since the origins of the West, designing worlds (or rather, events) that were defined based on them. It consists of three chapters: 1) Khôra, metaplace where phýsis gains the features that give it intelligible contours; 2) Díesis, metaplace from which the absolute emerges, where the double composition of natura and subjectivity is inscribed; 3) Sýnkhysis, metaplace where Babel s translation is seen in turbulent chaos in the production of differences. The platonic aegis khôra, the cartesian aegis díesis and the babelic aegis sýnkhysis form a triad of the metaplaces. The triadic structuring of the thesis, in three chapters, is not by chance. It corresponds to the intuition that each age of metaphysics comes to be dominated by a metaplace. Each era is drawn on the surface of a metalugar and it corresponds to the creation of a name. The name is like a shield. The thesis is, in other words, a metaplace that creates names of metaplaces, from which the fundamental concepts that weave each era are based. The metaplace is, in short, where the event of an era is drawn, the uterus from which the outbreak of your being and your becoming occurs.
