Metaphysics

Metaphysics

Prior to the modern history of science, scientific questions were addressed as a part of metaphysics known as natural philosophy. Originally, the term "science" (Latin scientia) simply meant "knowledge". The scientific method, however, transformed natural philosophy into an empirical activity deriving from experiment, unlike the rest of philosophy. By the end of the 18th century, it had begun to be called "science" to distinguish it from philosophy. Thereafter, metaphysics denoted philosophical enquiry of a non-empirical character into the nature of existence.

Empiricism -> Logical Positivism's Rejection of Metaphysics -> (poof)

Logical Positivism took the position of Empiricism, that statements about things that cannot be verified are meaningless (itself a non-empirical statement!), and took it to the extreme, and then imploded on itself, likely because it had to make non-empirical statements about non-empirical statements.

Kant -> Modern Analytic Metaphysics

Kant sought to replace Hume's skepticism and empiricism with a framework where analytic philosophy had something to contribute, but Kant was left behind during much of the twentieth century, until modern metaphysics made a resurgence.

According to the same Wikipedia article,

The analytic view is of metaphysics as studying phenomenal human concepts rather than making claims about the noumenal world, so its style often blurs into philosophy of language and introspective psychology. Compared to system-building, it can seem very dry, stylistically similar to computer programming or mathematics. Despite, or perhaps because of, this scientific dryness, it is generally regarded as having made "progress" where other schools have not. For example, concepts from analytical metaphysics are now routinely employed and cited as useful guides in computational ontologies for databases and to frame computer natural language processing and knowledge representation software.

It might not be BS if it is boring and dry. (Controversial, politically motivated sophistry—which says a lot without managing to say anything—is always exciting!)
