" Depressive realism has a very impressive pedigree. The Buddha pronounced that “all life is suffering” about 2,500 years ago, at roughly the time when the original Greek tragedies were composed. The Old Testament writers and prophets bequeathed us the concepts of human evil, sin, and the Fall, all this stemming from about the 5th century BCE when Adam behaved badly and doomed us all to suffering and death. From Paul through Augustine and Aquinas we have inherited the concept of original sin. The idea that we live in a “vale of tears” is probably from a Catholic hymn. Shakespeare put the phrases “to be or not to be” and “shuffle off our mortal coil” in Hamlet’s mouth in 1603. Robert Burton’s monumental The Anatomy of Melancholy was published in 1621 and George Cheyne’s The English Malady in 1733. DR is hardly a wacky modern idea owing its existence to Enlightenment- denying pessimists or to 20th century existentialists. "
