Human language is a very flexible tool that allows us to generate a seemingly endless series of questions about the world we find ourselves in. Some aspects of the universe are very well hidden from us, so if we are curious about the world then we are driven to keep asking questions that cannot be easily answered. Some people find it frustrating to be subjected to these circumstances and hope that there is a "foundation", an ultimate set of questions and answers that will provide an end to our questioning.

What are the fundamental components of the universe? Points? Strings?

One modern incarnation of the desire for a solid foundation is found in attempts by physicists to devise a Theory of everything.
