Norman Mailer Quote

What if there are not only two nostrils, two eyes, two lobes, and so forth, but two psyches as well, and they are separately equipped? They go through life like Siamese twins inside one person.... They can be just a little different, like identical twins, or they can be vastly different, like good and evil.

Kittredge Gardiner, in Harlot's Ghost : A Novel (1991)
