'Stop at red' campaign

Hutch It's not a trick question! The 'tree falling in a forest' question is a really useful way of separating our realist and anti-realist theories. For instance, an idealist would say if no-one hears it (or is experiencing it) then not only does the tree not make a sound, but the tree itself does not even exist.

The question is a trick question in the respect that it equivocates the word 'sound'.

Clarify what it is you mean by sound and the question answers itself.
