If philosophy is capable of astonishment, its most astonishing moments occur when two of its most radical — and seemingly most contradictory — ideas intersect: wahdat al-wujud (the Unity of Being) as formulated by Ibn Arabi, and the multiverse as depicted by some contemporary physicists. The first says: being is one. The second says: worlds are innumerable. Is there a real contradiction between them, or are they, at their core, saying the same thing in two languages from two different eras?
Unity of Being: Not Unity of the World
Many misunderstand wahdat al-wujud, imagining it claims that God is nature, trees, and human beings — a pantheistic unity that dissolves the Creator into the created. But Ibn Arabi draws a strict distinction between the Real in Himself (absolute being) and His manifestations, or determinations (ta’ayyunat). The doctrine’s core can be reduced to one precise claim: true being is one, but its manifestations are infinite. Things are “mirrors” reflecting God’s names and attributes to varying degrees, and tajalli (theophany) is Ibn Arabi’s name for this infinite, dynamic process — God never manifests in the same form twice, hence the saying: “Every day He is in a different state.”
The Multiverse: Not a Centerless Chaos
The multiverse is not a single idea but a cluster of distinct theories sharing one feature: our world is not all that exists.
- Everett’s interpretation: the wave function does not “choose” a single path upon measurement; it branches into parallel outcomes, all equally real.
- Eternal inflation (Guth/Linde): some inflationary models predict pockets of space expanding at different rates, generating separate “cosmic islands.”
- The string landscape: string theory suggests roughly 10⁵⁰⁰ possible configurations of nature’s constants.
Where the Parallel Actually Breaks Down
The quick comparison says: multiplicity of worlds equals multiplicity of theophanies. But this conflates two different senses of “multiplicity.”
Wahdat al-wujud holds that the determinations are not independent — their independence is illusory, and they derive their entire existence from a single reference point. Everett’s interpretation, however, if taken at full ontological weight, makes the branching outcomes fully real and fully independent of one another — with no central reference uniting them as a single theophany. This is not multiplicity-within-manifestation; it is genuine multiplicity of existents — precisely what wahdat al-wujud denies. The other multiverse models (inflation, string theory) are, by design, decentralized structures that never assume a single source manifesting through them, so they lack the very condition that the concept of “theophany” requires from the outset.
So the real intersection here, if we want precision, is not between wahdat al-wujud and cosmic multiplicity, but between the human longing for infinity as it appears in two entirely different traditions — one that anchors infinity to a single manifesting source, and another that scatters it across sources with no center at all. That is a difference no metaphor can bridge, and it deserves to be stated plainly rather than dissolved into the language of “possible convergence.”
