"If a tree falls in a forest and no one is around to hear it, does it make a sound?" is a philosophical thought experiment that raises questions regarding observation and knowledge of reality.
Philosopher George Berkeley, in his work, A Treatise Concerning the Principles of Human Knowledge (1710), proposes, "But, say you, surely there is nothing easier than for me to imagine trees, for instance, in a park [...] and nobody by to perceive them. [...] The objects of sense exist only when they are perceived; the trees therefore are in the garden [...] no longer than while there is somebody by to perceive them." Nevertheless, Berkeley never actually wrote about the question.
Franklin and the Green Knight (also known as Franklin and the Green Knight: The Movie) was the first ever Franklin movie, released direct to video and DVD in 2000. It has since aired on Noggin and Nick Jr. in the United States, and Canada's Family Channel.
Franklin is excited about the coming of spring, because his parents have told him he'll become a big brother then. After talking with his friends about it, though, he begins to have mixed feelings. His mother reads a tale known throughout Woodland called The Quest of the Green Knight and Franklin decides to go on his own quest to end the unusually long winter, with his friend Snail as his squire.
