Secondary Causes? Not really.

So i had read something really interesting about Zwingli on secondary causes. Ill quote it later but it was interesting. He essentially says he does not believe that secondary causes are legitimate causes or should be called such things as cause for God alone is the true cause.What is a good way of talking about this? in my language its hard to speak without using secondary cause.

- Assumed secondary causes are nothing more than the observable effects of the immediate cause. It's a matter of perception, but only one is truth, for truth is objective and not subjective.
