You: I'm sure you would, but I am not going to let you. I believe it would be difficult for you to argue that a rose has any desire. I would argue that it is impossible for something to have desires without having free will.

Aaron: True, but every action that a rose takes helps it to stay alive or reproduce itself. It fits into my definition quite nicely without bringing desire into the argument.

You: Well then, what about a diamond? A diamond has no desire and it acts to sustain its life by resisting breakage.

Aaron: Come now, we both know that a diamond is not alive.

You: We have not decided what life is so you cannot say that a diamond does or does not have it.

Aaron: I can say that a diamond is not alive and that a rose is because both of these facts are obvious. I am quickly growing tired of your linguistic games.
