If you were to randomly target any time in human history you would likely find people contemplating the world as it is and the world as they want it to be. It’s a much more complicated idea than breaking human beings down into “realists” and “idealists”.
No one seems to know exactly what happiness is, but it appears to contain the component of “hope”. How then does one hold onto hope in a world that in many ways looks like it has gone mad?
It is up to each individual (if he or she wants to) to develop a solution for finding his or her own form of being happy, possibly taking into consideration the world as it is and the world as we want it to be.
