Exposure, singular. Double exposed.
So John Donne got it wrong in Devotions Upon Emergent Occasions, Meditation XVII:
Now, vanity triple exposed. And finally, self-exposure: really exposed, and really stoked on it. All images from the Square America project.
All mankind is of one author, and is one volume; when one man dies, one chapter is not torn out of the book, but translated into a better language; and every chapter must be so translated....No man is an island, entire of itself...any man's death diminishes me, because I am involved in mankind; and therefore never send to know for whom the bell tolls; it tolls for thee.
