Actually, I was referring to this Rousseau:
I fully agree with the parallel you have drawn between cubism and the WWI camouflage. I was musing on the irony that when a Philosopher set out to do a confession, his attempts at humility was dismissed as a subterfuge to flatter his vanity, and his confessions, a camouflage. While when an artist was commissioned to paint a camouflage, it became a truer reflection of himself and his time, a self portrait.
But of course none of that came though my previous post, I was talking in bubbles. Sorry. I really should leave the writing to those who are good at it
