Book that will remain relevant for as long as man exists. Context may change, but the main ideas will still be there.
might be tedious to read at first, but it gets easier to read as you keep going.
To those who say it is 'too hard to read' or 'too many words'; if you were ever in high school and learnt English, you should be able to do it.
Also if you can't understand any words, there is a site called 'Google' that you can use to look up the words.
Good read overall.
