Shiavault - a Vault of Shia Islamic Books Philosophical Instructions Lesson Thirty-One: Cause and Effect Introduction With the acceptance of a multiplicity of existents, the question arises as to whether or not different existents have any relation to each other, and whether or not the existence of some of them depends on the existence of others. If there is such a relation, how many kinds of dependence are there? What are the principles and characteristics of each of them?
However, if someone does not accept the real multiplicity of existents as is the apparent view of some, then there is no room for discussion about existential relations among various existents, and likewise there would be no call for discussion of the various kinds of existence and existents. In the previous discussion, we indicated that the proof of a special gradation in existence depends upon a principle which must be established in the discussion of cause and effect.
Now the time has arrived for us to pay heed to the problems of cause and effect and to establish the mentioned principles. However, before delving into these matters some explanation must be given about the concepts of cause and effect and how the mind becomes acquainted with them. The Concepts of Cause and Effect In philosophical terminology, the word ‘cause’ is used in a general and in a.specific sense.
The general concept of cause is applied to an existent upon which the realization of another existent depends, even if it is not sufficient for this realization. The specific concept is applied to an existent which is sufficient for the realization of another existent. In other words, in its general sense, a cause is an existent without which realization of another existent is impossible. In its specific sense, a cause is an existent whose existence requires the realization of another existent.
It is noteworthy that the first sense is more general than the second, because it includes conditions and prerequisites and other incomplete causes, unlike the second sense. The explanation of complete and incomplete causes, as well as other kinds of causes, will follow. We should take note of the point that a dependent existent (i.e.
an effect) is called an effect solely with respect to its aspect of dependence and in relation to the existent upon which it is dependent, not with respect to any other aspect nor in relation to any other existent.
