Who is William Shakespeare, Anton Chekhov from The Empty Space and what is their importance?

In contrast to the artists listed above, these two renowned playwrights (according to the author) develop and define their search for the holy in theatre with an emphasis on structure, on text, and on form. The author contends that in their own way, these dramatists are as successful in creating a blend of rough and holy as the more contemporary artists listed above—the profound insights of Shakespeare and Chekhov, he contends, are equally as revelatory of human truth as their more impulsive, less shaped works.
