I guess I'm hoping that you're not being deliberately obtuse. Hence my response.

My quote "the air we/you breathe was once the breath of another"

Your response: "We do not breath recycled air from other people. We breath the oxygen that is emitted from plants."

Without mentioning photosynthesis and the other chemical components of the air we breathe. What is false about my statement? Is the air you're breathing from a source outside the earth's eco-system?

Regarding truth I'll repeat something I posted earlier as part of another thread since I perceive it as germane to this particular exchange.

- What reveals itself to me ceases to be mysterious—for me alone: if I unveil it to anyone else, he hears mere words which betray the living sense: Profanation, but never revelation. Egyptian Proverb.
