This morning I found this article on pop(ular) philosophy and BS.

The Vienna Circle’s preferred term for bullshit was ‘metaphysics’, and so their 1929 manifesto, the Wissenschaftliche Weltauffassung (“Scientific World-Conception”), led off with the worry that “metaphysical and theologizing thought is again on the increase today, not only in life but in science.” The “Scientific World-Conception” would be the antidote. It was an embrace of modern science and a scientific attitude toward things, as well as the “new objectivity” (or neue sachlichkeit) pursued by many artists, designers and architects in European culture.

The Vienna Circle’s target was not the intellectual diversity that surrounded them, but the putative parts of it that were presented (even accepted) as meaningful—indeed, profoundly meaningful—but in fact amounted to nothing. In 1932, the Circle’s Rudolf Carnap criticized Martin Heidegger, perhaps the most prominent German-speaking philosopher of the time, on precisely these grounds.

In his 1929 book, What is Metaphysics?, Heidegger ruminated on the nature of Das Nichts (literally, “the nothing”), and inspired Carnap to figure out exactly what was wrong with such supposedly deep and insightful metaphysical inquiries. In statements like Heidegger’s ‘Das Nichts selbst nichtet’ (“The nothing nothings”), Carnap concluded, there was only the appearance of a meaningful statement. Behind that appearance, there was Nichts, leading Carnap to suggest that metaphysicians were like “musicians without musical ability.”

Had Carnap read more carefully, he'd have discovered that Heidegger was a great critic of metaphysics, and that he goes on to demonstrate that the proposed antidote, scientific attitude, is also metaphysics.  ¶ 10:19 AM
