Mormon Philosophy & Theology on the
Ontological Difference:
When Heidegger often talks about how Being is forgotten really what is he talking about is how this difference between the two senses of being is forgotten. The difference between Being and beings. Because people forgot about the difference metaphysics was born. With metaphysics basically treating Being as an entity.
In addition to becoming another entity, being was also used as a boolean property of an object. An object could have the property of existing or not. And classes could also have a being property, the property could be true and class real (e.g. horse) or false and the class not exist (e.g. unicorn).
