Existential theorists have been working to syncretize philosophy, science, and spirituality since shortly after Galileo unknowingly initiated the schism between them. Contemporary philosophers, scientists, and theologians are still engaged in this effort, but have little to show for nearly four centuries of effort. The thesis of this article is that—despite their cooperative intentions—these theorists continue to talk past each other, due to an unacknowledged disagreement on the meaning of their overlapping terms of art. To effectively unify the divergent existential insights of philosophy, science, theism, and spirituality, it will be necessary to return to first principles. To establish an integration baseline, this article defines a diverse collection of philosophical, scientific, theistic, and spiritual expressions, in a unifying vocabulary.

Modal idealism is a Theory of Everything, based on metaphysical abstractions of the physical principles of hidden symmetries, entanglement, and quantum field theory, considered in the context of the Many Worlds Interpretation of quantum mechanics. These abstractions are used to extend the scope of existing philosophical positions on idealism, consciousness and possible world semantics, to rationally explain the fundamental mysteries of our existence. While it conceptually aligns with the Many Minds Interpretation of quantum mechanics, modal idealism posits a more comprehensive characterization of the mind, and thereby addresses many of the objections to MMI and MWI. Consequently, it can provide unequivocal, logical answers to our most enduring existential questions. To demonstrate the explanatory power of modal idealism, this article will present seven of our most meaningful physical and metaphysical questions, enumerate the principles of this framework, and use them to rationally answer these questions.
