On my big not-read-yet book stack, there's Husserl's Ideas I. Still a long way to finish it, but I was more than impressed on his refutation of naïve empiricism. It's one the clearest I read, which isn't particurlay important given that I didn't reach much philosophical treatise. That said, I'm gonna keep this passage to give it to the "scientist-ist" that are too many in my immediate social circle.
Moreover, I've also in my backpack a book from a french "skeptic" on evolution, - which isn't too bad honestly, its "new-atheist" side put away -, and "Comment peut tout-s'effondrer", which is a analysis of our modern civilization by two scientist, and its doomed collapse, or so the authors think.
I shouldn't probably read many books at once: I always end by forgetting where I was.
