Infamous Bridge-Burner Offers Highly Subjective Opinion On Writing . No wonder John Gardner didn't write more fiction books.  He was far too preoccupied with what he believes makes good fiction, rather than actually writing it.  "Creative atrophy" I believe John Gardner himself would call it.  If there's ever been a better example of the "those who can't do, teach" argument, I haven't encountered it.  This is hardly the place a "Young Writer" should start.  Instead, how about reading what you like and avoiding "ignoramouses" such as John Gardner?  John Gardner is unable to accept the fact that many of the world's finest writers never made it through college, and many more didn't have the luxury of a "rigorous classical education."   The most hilarious part is where Gardner mentions that only through a line-by-line university level discussion will anybody ever be able to fully enjoy Shakespeare.  It's interesting to note how Gardner, who "taught" creative writing at the university level, fails to exhibit the critical thinking and objectivity he says one can only obtain through a college education

Ex Output:

Preposterous! . This book begins with the absurd claim that 'the natural numbers -1, 2,3, 4 etc- appear to have been present at the birth of the universe; part and parcel of the original material from which was knit the ever-expanding continuum of space-time.' The author does not explain in whose mind these numbers are supposed to have appeared or how a concept can be present without a mind to concieve it. Like many mathematicians he seems unable to grasp that mathematics is a language. Thus it's not uncommon to hear ridiculous statements like 'the universe is governed by mathematics' As if numbers exert forces. But this is the first time I've encountered the claim that numbers existed prior to life!

Ex Output:
NEG

Only slightly better than Throne . Not quite the crapfest that was book 3 in the Ringworld series, but still a gigantic disappointment coming from Niven.  Children is plagued by the same things that made the previous novel so unbearable: flat, uninteresting characters, ridiculous names, obsession over interspecies sex for no reason other than to include sex in the story, and overall a poorly written plot.  To be fair, I didn't come out of this one as bewildered as after Ringworld Throne - don't even ask me to summarize THAT plot, I've yet to come across a decent one myself, mostly because trying to figure it out can cause lasting brain damage.  But even so, this novel is nowhere near the original Ringworld novel, or even Engineers for that matter.  Avoid if possible
