I'll help!
1. He's not a serious political scientist; he's a political theorist, and there's a huge difference. Serious political scientists engage in positive, as distinct from normative, analysis. Chomsky is essentially a guy with opinions looking for some sort of philosophical-political framework to support them. If you like that kind of thing, by all means, go for it. But that makes him no better than a highly educated talk-show pundit.
2. He engages in insane, outrageous false equivalencies with regard to U.S. foreign policy and other superpowers. It's true that the U.S. did some highly questionable things during the Cold War to roll back communism, but if you look at our foreign policy on balance, the Soviet Union was waaaaaay worse. Again, this is symptomatic of his being an opinionated author, not a serious political scientist. For example: "From my personal experience there are two countries in which my political writings can basically not appear. One is the U.S. within the mainstream with very rare exceptions. The other is the USSR." That is a ridiculous exercise in false equivalence.
3. Chomsky prides himself on being a libertarian socialist or an anarcho-syndicalist or whatever kind of outmoded turn-of-the-century utopian ordering principle happens to be in vogue among bohemian academics. I guess you can believe whatever you want, but I think it's functionally useless to society and intellectually dishonest to support the establishment of a system of government that is both completely unobtainable and not even very attractive for the vast majority of people.
Sorry for hijacking the thread hahah.
Re: the actual thread, anything by Stephen Hawking is also amazing. It's a little science-heavy, but reading it will fill you with a constant sense of awe at the universe similar to Sagan's writing.
