I actually finished Stranger in a Strange Land by Robert Heinlein quite quickly – in about three late night reading sessions. Having read it, I strongly urge you to read the complete version – it was originally published with several thousand words cut out as per the publisher’s request – because I really think that it is truly complete the way it is.
Stranger is about this man Michael Valentine Smith who was born and raised in Mars, away from all human contact. When he is brought to Earth, he must cope with this strange planet with not only a different gravity and language, but strange ideas such as jealousy and love.
I understand a bit why hippies seem to love his work (being a teensy bit of a hippie myself) but I have never been able to come to grips with the idea of free love. It’s the one thing that I am most unable to fathom of all the socially liberal tendencies out there. I did, however, truly enjoy the discussion of total emotional and spiritual connections – the idea of “grokking”.
Read this book – there’s a reason why it’s famous!
