The Causality Principle

The proposition “Any essentially possible being requires a cause” must be considered as the precise wording of the causality principle. This is because according to principality of quiddity, the essential possibility is the criterion for quiddity’s need of a cause, and according to the principality of existence, it is the sign for the of need of its existence to a cause. As for the attributes of the things, this principle is stated as “the accidental is caused”. This is in contrast to “the essential is not caused” which refers to the fact that the thing’s essential attributes do not require a cause. The causality principle is itself a certain statement of the special mode of the principle of “impossibility of preponderance without a preponderant” and is reduced to it. Thus, as far as self-evidence and non-self-evidence as well as provability and non-provability are concerned, it follows that principle; and as that principle is non-provable evident, so is the causality principle. From the principle of “impossibility of preponderance without a preponderant”, another principle is derived as follows: the principle of “impossibility of giving preponderance without a preponderant” which is the statement of the principle “impossibility of preponderance without a preponderant” for the free-willed agent and his volitional actions, and is non-provable evident just like it
