Famous quotes containing the words thread and/or form:
“Fate forces its way to the powerful and violent. With subservient obedience it will assume for years dependency on one individual: Caesar, Alexander, Napoleon, because it loves the elemental human being who grows to resemble it, the intangible element. Sometimes, and these are the most astonishing moments in world history, the thread of fate falls into the hands of a complete nobody but only for a twitching minute.”
—Stefan Zweig (18811942)
“Touch me not.”
—Bible: New Testament Jesus, in John, 20:17.
Spoken to Mary Magdalene, after Jesus has risen from the dead and made himself known to her. The words are best known in the Latin form in which they appear in the Vulgate: Noli me tangere.
