Uhm I take it that You just giving an advice, and that's cool.
I myself can't deny that I've read Lem's books in order that is a realisation of a pure chaos, and honestly, it's not such a big loss as long as You're trying to understand what You read and stuff.
But then of course people who are only at the beginning of their Lem adventure would somehow benefit from applying the order You're advertising... I guess.
And to sum it up: why not experiment, man !
