  In this paper, we propose a mathematical model of subjective experience in
terms of classes of hierarchical geometries of representations ("n-awareness").
We first outline a general framework by recalling concepts from higher category
theory, homotopy theory, and the theory of (infinity, 1)-topoi. We then state
three conjectures that enrich this framework. We first propose that the
(infinity, 1)-category of a geometric structure known as perfectoid diamond is
an (infinity, 1)-topos. In order to construct a topology on the (infinity,
1)-category of diamonds we then propose that topological localization, in the
sense of Grothendieck-Rezk-Lurie (infinity, 1)-topoi, extends to the (infinity,
1)-category of diamonds. We provide a small-scale model using triangulated
categories. Finally, our meta-model takes the form of Efimov K-theory of the
(infinity, 1)-category of perfectoid diamonds, which illustrates structural
equivalences between the category of diamonds and subjective experience (i.e.
its privacy, self-containedness, and self-reflexivity). Based on this, we
investigate implications of the model. We posit a grammar ("n-declension") for
a novel language to express n-awareness, accompanied by a new temporal scheme
("n-time"). Our framework allows us to revisit old problems in the philosophy
of time: how is change possible and what do we mean by simultaneity and
coincidence? We also examine the notion of "self" within our framework. A new
model of personal identity is introduced which resembles a categorical version
of the "bundle theory"; selves are not substances in which properties inhere
but (weakly) persistent moduli spaces in the K-theory of perfectoid diamonds.
