How does William Golding present 'the beast' in Lord of the Flies?

William Golding presents 'the beast' in Lord of the Flies as the fear and superstition of the boys. (The boys imagine that a monster in the form of a snake, a sea monster, an ape, or other......."beasties" that they dream about lurks nearby.) It also represents the evil inside all of the boys hearts when they turn into savages.
