Modern Relevance of Invisible Ink Messages
As an indication of security, most inks mentioned above were already known by the end of World War I. However, in 1999, the U.S. Central Intelligence Agency successfully requested that a 1940s technical report on invisible ink remained exempt from mandatory declassification, based on the claim that invisible ink was still relevant to national security. The report thus remained classified until 2011.
Former MI-6 agent Richard Tomlinson alleges that Pentel Rolling Writer rollerball pens were extensively used by MI-6 agents to produce secret writing (invisible messages) while on missions.

“Every modern male has, lying at the bottom of his psyche, a large, primitive being covered with hair down to his feet. Making contact with this Wild Man is the step the Eighties male or the Nineties male has yet to take. That bucketing-out process has yet to begin in our contemporary culture.”
—Robert Bly (b. 1926)
“The most striking fault in work by young or beginning novelists, submitted for criticism, is irrelevance—due either to infatuation or indecision. To direct such an author’s attention to the imperative of relevance is certainly the most useful—and possibly the only—help that can be given.”
—Elizabeth Bowen (1899–1973)
“The caretaking has to be done. “Somebody’s got to be the mommy.” Individually, we underestimate this need, and as a society we make inadequate provision for it. Women take up the slack, making the need invisible as we step in to fill it.”
—Mary Catherine Bateson (20th century)
“Who does not see that I have taken a road along which I shall go, without stopping and without effort, as long as there is ink and paper in the world? I cannot keep a record of my life by my actions; fortune places them too low. I keep it by my thoughts.”
—Michel de Montaigne (1533–1592)
“All the old supports going, gone, this man reaches out a hand to steady himself on a ledge of rough brick that is warm in the sun: his hand feeds him messages of solidity, but his mind messages of destruction, for this breathing substance, made of earth, will be a dance of atoms, he knows it, his intelligence tells him so: there will soon be war, he is in the middle of war, where he stands will be a waste, mounds of rubble, and this solid earthy substance will be a film of dust on ruins.”
—Doris Lessing (b. 1919)
