All the forces in the world are not so powerful as an idea whose time has come.

Short as life is, we make it still shorter by the careless waste of time.

An invasion of armies can be resisted, but not an idea whose time has come.

Nothing else in the world... not all the armies... is so powerful as an idea whose time has come.

There is one thing stronger than all the armies in the world, and that is an idea whose time as come.
