I'm going to try to avoid recommending "tomes" in favour of "good reads", so:
"Stasiland" by Anna Funder - For a primer on why totalitarianism should be avoided at all costs.
"The Ragged-Trousered Philanthropists" by Robert Tressell - Because the picture it presents of a divided working class is still relevant today.
according to EinsteinA lucid representation of the fundamental concepts and methods of the whole field of mathematics...Easily understandable.
Very good choice.George Orwell's "A Hanging", you could read that waiting for a bus and spend the rest of the day thinking about it. Individuals, the system, complicity, guilt, humanity, the human desire for a little dignity, death penalty thoughts, colonialism, imposition of values, well written pieces...

i remembered One Day in the life of Ivan Denisovich by Aleksandr Solzhenitsyn, i think that's worth a read anytime. i found it to be a very powerful description of solitude and punishment, authority and attitudes arising from 'socialist' practice in the ussr. also worth a read are love on the dole by walter greenwood and the road to wigan pier by orwell, both evocative descriptions of working class destitution in their own ways.

Wealth of Nations by Adam Smith
I drew an entirely different set of impressions from it;I've just finished reading this, and it made me sick. Six hundred pages of embittered despair and the most unflattering portrait of the w/c I've ever come across. Self-righteous and preaching, it continually slams home the point that the workers are wretched and stupid, and concludes that they deserve to remain so as they refuse to speculate on or lend support to parliamentary socialism.
Enlightenment is more than enough.I can't see how this book has inspired or uplifted anyone, although I can see how it might have enlightened.
Wealth of Nations by Adam Smith
I drew an entirely different set of impressions from it;
that "the working man", having been told by his "betters" that Labour and/or socialist politics were "bad for business", saw their only recourse to be aping the views of those "betters", (hence the arguments between the painters about "protection" and "free trade"):
that organised religion could be used as a device for social control;
that you don't need to "convert" people, because you can inspre them by example;
that the belief that the bosses have any interest in you beyond maximising the surplus value of your labour deceived many people, and;
that in the end, if you don't make a stand you've no cause to complain.
That's not to say that the book isn't bitter, because it is. Tressell actually lived what he wrote. One would expect him to be bitter.
As for his unflattering portrayal of the working class, you're talking about a time where the older males wouldn't have been submitted to compulsory education, where conditions for the mass of the working class really were that piss poor, and where your employer knew and might even play on the fact that he was what stood between you and the workhouse.
Enlightenment is more than enough.
What I really dislike is the tone of the book and the repeated implication that the situation is so hopeless that you'd be better off murdering your family and then committing suicide. There is a sharp contrast between the sophistication of the socialists (i.e. Owen and Barrington) and the beyond-salvation barbary of the rest of the w/c. Enlightenment is meaningless if with that knowledge you also acquire the belief that the w/c is too dense and savage to ever see the truth.
Well I think it is a literary work so some incidents are more dramatic than representative. Parts of the novel are designed to shock you and wake you up to a possible consequence of poverty.
The difference between the socialists and the other workers can be a bit stark sometimes (the vernacular in some and lack of it in others doesn't help) and as mentioned I personally find Barrington a bit surplus to the novel. However there are a couple of characters who I think manage to avoid being strictly one or the other; Easton and Harlow (towards the end) spring to mind. What is also telling is that Barrington and Owen may be frustrated and at times look down on fellow w/c but they don't give up fighting and trying to spread their message.
Why?
because it matches reality closer than Marx
I've never found that reading any one book has made me any more enlightened about anything - often I have read 'great texts' or other canonical literature and ended up thinking 'so what?' I also wouldn't say that I actually 'know' them per se.What books would you recommend that everyone should know?
