The lecture series on Marx by Prof. Robert Paul Wolff. This week it's at its 3rd. If u're a zombie, don't pay attention to it.
This type of work (thank you, Professor) is what academics should be doing, instead of converting public money (their salaries) into private money (copyrighted knowledge), as they do now.
I would've recommended his book "Understanding Marx", but it's under copyright.
BTW, here's what "knowledge society" means, it's not what you thought: a society awash with knowledge, nope; it's a society hoping to extract rent from copyrighting whatever it touches (see WIPO, TRIPS and future like-horrors). Unsurprisingly, societies trying it become failed societies: knowledge is not shared (because you're supposed to make it a commercial item), so citizens become, individually, as intelligent as their pocket.
Circulation of knowledge degrades into the circulation of money. It's not bad just because it is a backward thing to do, but bullshit is promoted to "knowledge" just because its owners would be able to sell more copies of it. Just watch. Internet was supposed to allow collectively the society jump into a wiser, more knowledgeable state, instead, the legal notions of copyright and intellectual property are hoarding more economic power for some few, who never had a special relation with the creation of knowledge in the first place.
If u're a zombie, don't fight back the above with the creative commons license (CC) for intellectual works in general or GPL license, for software. If u want your children, or the society around you, grow stupid, don't use any of these and ignore this message, don't give it a
like, it has no use of it.
