One or Many

The certainty gives one experiencing, never one universal ground and never a ban on many. The pull toward one (parsimony, and the interaction argument that any relation needs a shared ground) against pluralism, mapped to the monotheism-versus-polytheism question. Monism the better bet, not a proof; an undecidable sealed-off plurality left open. Sources and weights.

The essay One Ground, or Many? is the readable version. This is the tagged backing.

The certainty (Foundations, rung 0) gives exactly one experiencing, this one, now. It does not give one universal ground, and it does not forbid many. So the question is open. FRAMING

The pull toward one

  • Parsimony FRAMING. One is simpler than many; a reason to prefer, not to believe.
  • The interaction argument FRAMING. If several grounds interact, the medium of interaction is a deeper shared ground (collapse to one); if they do not interact, they are causally sealed off, unknowable in principle, and "how many" is unanswerable. So: effectively one, or an undecidable sealed-off plurality. Associated with F. H. Bradley (monism from the nature of relations).
  • Priority monism FRAMING. What is basic is the whole (the cosmos); parts derive from it by a non-causal grounding relation. Jonathan Schaffer, "Monism: The Priority of the Whole" (2010). Distinguished from existence monism (the stronger, less defended claim that only one object exists at all).

The pull toward many

  • Pluralism FRAMING. The world is a multiverse, not a universe; the experienced manyness is the real datum and the single Absolute is an imposed abstraction. William James, A Pluralistic Universe (1909); his radical empiricism. A live minority.

The theological mapping FRAMING

Monotheism versus polytheism is this question in another vocabulary. Polytheism reads two ways in the aspect model: many dreamers (creator-minds) over one canvas (shared ground), or a genuine plurality of grounds. On the first reading, "one god" and "many gods" are not a flat contradiction, because they count different aspects. The model does not adjudicate a given tradition's intent; it dissolves the automatic contradiction and shows the metaphysical and theological questions are one.

Calibrated weights

Claim Weight Defeater
Reality is strictly one Not proven (n/a: it is the conclusion at issue)
Monism is the better-supported bet Yes A relation shown to need no shared ground
An undecidable plurality of sealed-off grounds UNDECIDABLE Real option A way to detect or rule out causally isolated grounds (which, being sealed off, there cannot be)
The manyness is fundamental (pluralism) Live minority A successful reduction of the many to one
