“The realms of advertising and of public relations, and the nowadays closely related realm of politics, are replete with instances of bullshit so unmitigated that they can serve among the most indisputable and classic paradigms of the concept. And in these realms there are exquisitely sophisticated craftsmen who — with the help of advanced and demanding techniques of market research, of public opinion polling, of psychological testing, and so forth — dedicate themselves tirelessly to getting every word and image they produce exactly right.
Yet there is something more to be said about this. However studiously and conscientiously the bullshitter proceeds, it remains true that he is also trying to get away with something. There is surely in his work, as in the work of the slovenly craftsman, some kind of laxity which resists or eludes the demands of a disinterested and austere discipline.”
This is by (as you probably know) Harry Gordon Frankfurt (born May 29, 1929), professor emeritus of philosophy, Princeton University and is taken from his 1986 essay ‘On Bullshit’.
Something everyone should read.
