This is what I like about some of these old school sci-fi authors: they don't fool you w/ crapy plot that just contains superepic-space-opera battles here or superduper-i-know-science-named weapons there.
I don't mind those but there should be present at least one solid underlying concept. Dick seems to excell here – he managed to include multiple hidden philosophical niceties worth of discussion over a beverage of your choice. Yet, the novel is still light and readable.
