Limes inferior - Janusz A. Zajdel

Argoland to perfidnie doskonale zorganizowany świat komputerowego porządku. Siedem klas intelektualnej przydatności obywateli. Nadzór i manipulacja, porządek wykluczający wolność i automatyzacja czyniąca obywatela zbędnym. Tak chory system musi generować najróżniejszej maści kombinatorów i bystrzaków próbujących przechytrzyć codzienność. Z tego światka wywodzi się Sneer, główna postać tej fantastycznej i nowatorskiej na polskim gruncie powieści stanowiącej właściwie gotowy scenariusz filmowy. To właśnie ten inteligentny kanciarz ma szansę rozpracować system tak nierealny i spychający Człowieka w niebyt, że wydawałoby się narzucony przez obcą cywilizację…
"Janusz dawał w swych książkach wzór odwagi i dowcipu, miał naturalny talent narracyjny, potrafił spożytkować i naukę, i fantastyczne przygody jako polityczne demaskacje bądź manifesty, w czym przypominał trochę swego mistrza Orwella. Ale też, tak jak Orwell w najlepszych dziełach, demonstrował rzadki pisarski dar trafiania w sedno."

Free will - Sam Harris

A BELIEF IN FREE WILL touches nearly everything that human beings value. It is difficult to think about law, politics, religion, public policy, intimate relationships, morality—as well as feelings of remorse or personal achievement—without first imagining that every person is the true source of his or her thoughts and actions. And yet the facts tell us that free will is an illusion. 

In this enlightening book, Sam Harris argues that this truth about the human mind does not undermine morality or diminish the importance of social and political freedom, but it can and should change the way we think about some of the most important questions in life.

You Are Not So Smart

  • Why You Have Too Many Friends on Facebook, Why Your Memory Is Mostly Fiction, and 46 Other Ways You're Deluding Yourself

    An entertaining illumination of the stupid beliefs that make us feel wise. 
    You believe you are a rational, logical being who sees the world as it really is, but journalist David McRaney is here to tell you that you're as deluded as the rest of us. But that's OK - delusions keep us sane. You Are Not So Smart is a celebration of self-delusion. It's like a psychology class, with all the boring parts taken out, and with no homework.Based on the popular blog of the same name, You Are Not So Smart collects more than 46 of the lies we tell ourselves everyday, including: 
    • Dunbar's Number - Humans evolved to live in bands of roughly 150 individuals, the brain cannot handle more than that number. If you have more than 150 Facebook friends, they are surely not all real friends. 
    • Hindsight bias - When we learn something new, we reassure ourselves that we knew it all along. 
    • Confirmation bias - Our brains resist new ideas, instead paying attention only to findings that reinforce our preconceived notions. 
    • Brand loyalty - We reach for the same brand not because we trust its quality but because we want to reassure ourselves that we made a smart choice the last time we bought it.
