While we are "waxing philosophical" ... (ha ha) ...
It is interesting to note that the WAX is the soul, not the body. Parallel form is very important here: "soul ... body / wax ... figure". And, as in life, several things are apparent:
1. The wax existed before the figure impressed upon it.
Thus, the soul does not exist for the body, but the body for the soul.
2. The wax will outlast the impression. Time, heat or human marring will eventually remove the impression from the wax.
Likewise, the body will not always exist. But the soul will exist after the body is no longer "impressed".
3. There is a maker of both the wax and one to make the impression upon it. Impressions are MADE into wax, as wax is made. Neither exists of its own doing.
While no analogy describes a thing in every point, it does imply the existence of an overarching "higher power" - a Creator of body and soul.
These are the types of things that might typically be discussed in a philosophy class or debate. And, since philosophy is essentially "thinking about thinking" ... there will be no empirical answer.
(In case anyone doesn't know the use of the word, in my joke about "waxing philosophical", "to wax" means "to become, more and more; to swell".)
