Dark Night of the Soul

Factual Questions
1

Just a quick question-

What book does this line, “…the dark night of the soul…” come from?

I think I really need to read this, and I think it’s a philosophy book.

Thanks.

There is The Long Dark Tea-Time of the Spoul by Douglas Adams. But since you specified philosophy…well…I am not sure of Douglas passes muster.

There is a religious essay by that name, Dark Night of the Soul, by St. John of the Cross.

You can get more information about him at this site:
http://www.catholic-forum.com/saints/saintj23.htm
(although I cannot explain why it includes a picture of JC shooting St. John with some sort of laser tag gun)

The text is here:

I couldn’t find a publication date on the site, but St. John lived from 1542 - 1591.

From The Crack-Up by F. Scott Fitzgerald:

“In the real dark night of the soul it is always three o’clock in the morning.”
