No natural boundary seems to be set to the efforts of man; and what is not yet done is only what he has not yet attempted to do.
Alexis de Tocqueville

And where is the boundary-if there is a boundary-between a collective outlook and "the world"?. Many cultures assume such a boundary, but they set it in different places. Divine appearances once were real- they are mere fantasies today. Where shall we, who examine the phenomenon, set the boundary?
Paul Karl Feyerabend
Music is your own experience, your own thoughts, your wisdom. If you don't live it, it won't come out of your horn. They teach you there's a boundary line to music. But, man, there's no boundary line to art.
Charlie Parker
One could say: "The boundary condition of the universe is that it has no boundary." The universe would be completely self-contained and not affected by anything outside itself. It would neither be created nor destroyed. It would just BE.
Stephen Hawking
There ought to be something very special about the boundary conditions of the universe and what can be more special than that there is no boundary?
Stephen Hawking
Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted. That may be so, but it could also have made it evolve in a completely arbitrary and random manner. Yet all the evidence is that it evolves in a regular way according to certain laws. It would therefore seem reasonable to suppose that there are also laws governing the boundary conditions.
