Since so many of you atheists are so intent on eliminating the idea of 'metaphysics' from the conversation, let's take a close look at what the term would actually mean.
Etymology
The prefix comes from the
Greek preposition and
prefix meta- (μετα-), from μετά,
[3] which meant "after", "beside", "with", "among" (with respect to the preposition, some of these meanings were distinguished by
case marking).
Other meanings include "beyond", "adjacent" and "self", and it is also used in the form μητα- as a prefix in Greek, with variants μετ- before vowels and μεθ- "meth-" before
aspirated vowels.
Epistemology
In
epistemology, and often in common use, the prefix
meta- is used to mean
about (its own category).
For example, metadata are data about data (who has produced them, when, what format the data are in and so on). In a database, metadata are also data about data stored in a data dictionary and describe information (data) about database tables such as the table name, table owner, details about columns, – essentially describing the table.
On higher level of abstraction
Any subject can be said to have a metatheory, a theoretical consideration of its properties, such as its foundations, methods, form and utility, on a higher level of abstraction. In linguistics, a grammar is considered as being expressed in a
metalanguage, language operating on a higher level to describe properties of the plain language (and not itself).
Early use in English
The Oxford English Dictionary cites uses of the meta- prefix as "beyond, about" (such as meta-economics and meta-philosophy) going back to 1917. However, these formations are parallel to the original "metaphysics" and "metaphysical", that is, as a prefix to general nouns (fields of study) or adjectives. Going by the
OED citations, it began being used with specific nouns in connection with mathematical logic sometime before 1929.
Clearly, according to this info on wiki, the prefix, "meta" refers to an abstracted framework of understanding apart from, but adjacent to that which is being understood. In the case of gravity, for example; there is 'gravity' as a phenomenon, and there is 'gravity' as the cognitive experience/understanding of that phenomenon. And although the former can exist without the latter, it's existence would be unrecognized, and therefor completely irrelevant without the latter. To raise the physical phenomenon of gravity above the metaphysical recognition of the phenomenon in level of import and/of origin is logically incoherent, and the act of valuation itself is 'metaphysical'. It is therefor an argument that negates itself.
