Wonderful post, kyriacos. It captures what I've always thought about human nature. I loved the last three sentences:
We are all selfishly altruistic and always have been. Even the smallest random >act of kindness has a hidden egoistic motive. We just like to camouflage the >idea beneath an altruistic facade.
This reminded me of Leonard Read's 1958 essay "I, Pencil" and Adam Smith's concept of the "invisible hand".
It's all fascinating, thought-provoking stuff. Keep on posting!
I read the "invinsible hand" a while back @fenglosophy . Thank you reminding it to me. There is also a great animated video about I, Pencil. If you haven't seen it yet better check it out
