The world consists of objects, and every object is a content of positive or negative perception and cognition. The special feature of each object is that it is distinguished from the other by characteristics that are ingrained in it in a particular manner. This is why we see the world variegated in colours, sounds, tastes, touches, and smells. The difference is in the existence somewhere of some characteristics outside the range of others at other places. Thus, for example, we mark a difference between a cow and a tree, because we do not find in a cow the features of a tree, and those of a cow in a tree.
Objects manifest a mutual exclusion of one another.
It is this that enables us to know the multitudinousness that the world is. We also conceive such difference as that between God and the individual, God and the world, one individual and another, the individual and the world, in addition to the differences among the various contents of the world. There is a difference of limbs in the body. There is difference among individuals of the same species as also individuals of different species. There is external and internal variety.
