When we look upon the world of existence, we realize that all
material things have a common bond; and yet, on the other hand,
there are certain points of distinction between them. For instance,
all earthly objects have common bodily ties. The minerals, vegetables
and animals have elemental bodies in common with each
other. Likewise, they have place in the order of creation. This is
the common tie or point of contact between them. All of them pass
through the process of composition and decomposition; this is a
natural law to which all are subject. This law is ruling throughout
creation and constitutes a bond of connection among created
things. But at the same time there are certain distinguishing features
between these objects. For instance, between the mineral and
vegetable, the vegetable and animal, the animal and human,
points of distinction exist which are unmistakable and significant.
Likewise, there are distinctions between kinds and species of each
kingdom. When we consider the mineral kingdom in detail, we observe
not only points of similarity between objects but points of
distinction as well. Some are immovable bodies, some hard and
solid; some have the power of expansion and contraction; some are
liquid, some gaseous; some have weight; others, like fire and electricity,
have not. So there are many points of distinction among
these kinds of elements.
