Monism: Any antidualist philosophy that appeals to one unifying principle to explain all that is. In response to the metaphysical questions “How many things are real or exist?” monism answers, “Only one reality or thing” or “One kind of thing with many different things within that category” (attributive monism). In effect, monism allows for no distinction between God and creation.1
