frankenstein

"we rest; a dream has the power to poison sleep.
we rise; one wand'ring thought pollutes the day.
we feel, conceive, or reason; laugh or weep
embrace found woe, or cast our cares away;
it is the same: for, be it joy or sorrow,
the path of its departure still is free.
Man's yesterday may ne'er be like his morrow;
Nought may endure but mutability"
