Ex Input:
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


Ex Input:
Ok, an adverb...brilliantly . Daniel Handler is just one of the more vivid fiction writers out there. It's great to see him show his adult side with this collection of short stories which seek to explore his forays outside of Snicketville. I love the story where the character forces himself on the cabbie. Read this one by the pool this weekend. I'd love to see him write a non-Lemony novel, too

Ex Output:
POS
