That the only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others.
John Stuart Mill, On Liberty (1859)
One of the most salient features of our culture is that there is so much bullshit. Everyone knows this. Each of us contributes his share.[ …] So the phenomenon has not aroused much deliberate concern, or attracted much sustained inquiry. In consequence, we have no clear understanding of what bullshit is, why there is so much of it, or what functions it serves.
