Tropismes was one of those books I was supposed to have read in graduate school (but didn’t ). Instead read planétarium. However I can’t ever remember acquiring this text… But there it was on my shelf, all yellowed and marked up. It reads like a being from another era, really. Retro- avantgarde… Nothing ages like futuristic writing. I do have a certain affinity for the precursors of the nouveau roman.
