Philosophical question

My friend, Zane is a philosopher. I have always thought philosophers like Zane truly appreciate the profound nature of life's deep questions. As a result, people like Zane are still struggling with the same questions that have been asked for centuries. Thus, they are the objects of ridicule on the part of scientists, who have less patience with such lack of progress.
For example, Zane asked me the other day, "If a tree falls in a forest, and there is no one around to hear, does it make a sound?"
This question has been posed by philosophers since ages, and there is still no philosphical consensus as to what the answer should be.
But when a scientist is asked the same question, he'll go off for short while, apply for a grant or two, and come back saying, "Well, we've solved it for elm and birch, but we're still working on the general case"!
