The principle of causality, part one

Only being can cause being. Nothing does exists and only what exists can cause existence, since the very concepts of "cause" implies an existing thing that has the power to effect another. From absolutely nothing comes absolutely nothing.
The statement "Nonbeing cannot produce being" is undeniable. The very concept of "produce
 or "cause" implies something exists to cause or produce the being produce. To deny that relationship of cause to effect is to say, "Nothing is something" and "Nonbeing is being," which is nonsense.
