What we take from this soliloquy is that inflation is tougher to conjure up than it generally recognized.
Musicals seem to inherit from burlesque or pantomime or somewhere this informal variant of the soliloquy, the sly aside that breaks the fourth wall, steps out of the frame to engage with the audience directly.— Notes From The Geek Show
And still, the most damning charges of anti-Semitism come from a reading of the final soliloquy, which is worth quoting in bulk:
The famous "To be or not to be" soliloquy is about his internal struggles: he hates his uncle, he's angry at his mother but he's worried that the ghost might be a demon sent to trick him, so he has the idea of using a play to prove the King's guilt.— Conservapedia - Recent changes [en]
Did language begin as a soliloquy, or is the fundamental nature of language to be communicative?— Citizendium, the Citizens' Compendium - Recent changes [en]
