On Bullshit
Yes that really is the title of a book.
This slender (really, really slender) volume is an engaging analysis of what exactly makes bullshit bullshit.  Is it falsity?  Degree of insincerity?  Sheer volume of words?  It should only take you a few minutes to read the entirety of its 67 pages to find out but I should like to share a few quotes that were the highlight of the book for me.
“Bullshit is unavoidable whenever circumstances require someone to talk without knowing what he is talking about. Â Thus the production of bullshit is stimulated whenever a person’s obligations or opportunities to speak about some topic exceed his knowledge of the facts that are relevant to that topic. Â This discrepancy is common in public life…”
There then follows a brief and telling take-down of post-structuralism (without the naming of it as such) and this gem about the elevation of sincerity over correctness:
“Convinced that reality has no inherent nature, which he [the bullshitter] might hope to identify as the truth about things, he devotes himself to being true to his own nature.  It is as though he decides that since it makes no sense to try to be true to the facts, he must therefore try instead to be true to himself.”
An incisive little volume as far as it went, which wasn’t far…
