“The body, love, death, these three are just one.”
Hans Castorp to Chauchat, in French, Ch. 5
The Magic Mountain (1924)
Context: Rough translation of this passage written in French: The body, love, death, these three are just one. For the body, this is the disease and exquisite delight, and this that does die, yes, they are carnal both of them, love and death, and thus their terror and their great magic!
Original
Le corps, l'amour, la mort, ces trois ne font qu'un. Car le corps, c'est la maladie et la volupté, et c'est lui qui fait la mort, oui, ils sont charnels tous deux, l'amour et la mort, et voilà leur terreur et leur grande magie!

“The death of one man is a just death, the death of two millions is a statistic.”
Aber das ist wohl so, weil ein einzelner immer der Tod ist — und zwei Millionen immer nur eine Statistik.
Der schwarze Obelisk (1956)
A variant of this quote "One death is a tragedy. A million deaths is just a statistic." has also been attributed to Joseph Stalin, but no source for this has been found. This version appeared in the English press not later than 1958. (Ремарк, Эрих Мария // Словарь современных цитат / составитель К. В. Душенко — Москва: изд-во «Эксмо», 2006)

“The death of one is a tragedy, but death of a million is just a statistic.”
Being from Manson's Fight Song of Holy Wood, this is actually a quote from German writer Erich Maria Remarque, also often misattributed to Josef Stalin.
