Here we are, thrown into a world in which we have to live. We did not choose to exist, we did not create ourselves nor did anyone consult us as to whether we wanted to live. It has just happened to us that we have, so to speak, wakened up in a world and grown up in a world, where we become conscious that we have to make our lives with whatever resources we have and along with all the other people who have to make their lives in the same world.         

So if we use our minds at all, we cannot help wondering what is going on. What is it all about? Is there any meaning to it?
