[DiogenesKynikos]

That's a great episode, but the question of whether anything has a soul is ill defined.

Until someone can come up with a rigorous definition of what a soul is, the question itself has no meaning.

There are plenty of very rigorous definitions of what a soul is, though. Judging by your screen name I take you're already familiar with Aristotle, so what's your issue with his hierarchy of souls (vegetative, sensitive and rational)? Each one of those is as well defined as it can be within his logical system.
