The most influential recent proponent of a version of core pluralism has been Huston Smith. (b. 1919) In his view, the common core of religions is a tiered worldview. This encompasses the idea that physical reality, the terrestrial plane, is contained within and controlled by a more real intermediate plane (that is, the subtle, animic, or psychic plane) which is in turn contained and controlled by the celestial plane. This celestial plane is a personal God. Beyond this is infinite, unlimited Being (also called “Absolute Truth, “the True Reality,” “the Absolute,” “God”). Given that it is ineffable, this Being is neither a god, nor the God of monotheism. It is more real than all that comes from it. The various “planes” are not distinct from it, and it is the ultimate object of all desire, and the deepest reality within each human self. Some experience this Being as if it were a god, but the most able gain a non-conceptual awareness of it in its ineffable glory. Smith holds that in former ages, and among primitive peoples now, such a worldview is near universal. It is only modern people who are blinded by the misunderstanding that science reveals all, who have forgotten it. (Smith 1992, 2003 ch. 3) The highest level in some sense is the human “Spirit,” the deep self which underlies the self of ordinary experience. Appropriating Hindu, Buddhist, and Christian language, Smith says that this “spirit is the Atman that is Brahman, the Buddha-nature that appears when our finite selves get out of its way, my istigkeit (is-ness) which…we see is God’s is-ness.” (Smith 2003 ch. 3, 3-4)
Logical pluralism can be defined a number of ways: the position that there is more than one correct account of logical consequence (or no single, 'correct' account at all), that there is more than once correct set of logical constants or even that the 'correct' logic depends on the relevant logical questions under consideration (a sort of logical instrumentalism).  Pluralism about logical consequence says that because different logical systems have different logical consequence relations, there is therefore more than one correct logic. For example, classical logic holds that the argument from explosion is a valid argument, but in Graham Priest 's paraconsistent logic - LP , the 'Logic of Paradox' - it is an invalid argument.  However, logical monists may respond that a plurality of logical theories does not mean that no single one of the theories is the correct one. After all, there are and have been a multitude of theories in physics, but that hasn't been taken to mean that all of them are correct.
