Défiez-vous des premiers mouvements, ils sont presque toujours bons.

“The cold heart will burst
If mistrusted first
And a calm heart will break
When given a shake”

Context: In the middle of a lecture I would have a sudden very clear experience of men on the march up the Béthune–La Bassée road; the men would be singing... These daydreams persisted like an alternate life and did not leave me until well in 1928. The scenes were nearly always recollections of my first four months in France; the emotion-recording apparatus seems to have failed after Loos.
