However, these issues still are a matter under philosophical discussion.

There is nothing like a good philosophical discussion to take a man's mind from his physical problems.

"Isn't it just a little early in the day for these dense philosophical discussions?"

This is neither the time nor the place for a philosophical discussion of what makes a human.

I wasn't asking so we could get into a deep philosophical discussion.

"We didn't get into any philosophical discussion over it," he said.

It was feeling more like a philosophical discussion than anything else.

"And anyway, this is a fine time for a philosophical discussion!"

"This is hardly the time for a philosophical discussion of love."

This is rather like an attitude one might take to the philosophical discussions about whether we have free will or not.
