'a naked quivering heart'

The war, or rather, war, was odd, he told himself a little inanely. But he knew what it meant. It was all covered with tedium and routine, regulations and procedure, and yet there was a naked quivering heart to it which involved you deeply when you were thrust into it. All the deep dark urges of man, the sacrifices on the hilltop, and the churning lusts of the night and sleep, weren't all of them contained in the shattering screaming burst of a shell, the man-made thunder and light?

—Norman Mailer, The Naked and the Dead (1948)
