Analyze the structure of the analogical arguments in the following passages, and evaluate them in terms of the six criteria that have been explained:

The body is the substance of the soul; the soul is the functioning of the body. . . .The relationship of the soul to its substance is like that of sharpness to a knife, while the relationship of the body to its functioning is like that of a knife to sharpness. What is called sharpness is not the same as the knife, and what is called the knife is not the same as sharpness. Nevertheless, there can be no knife if the sharpness is discarded, nor sharpness if the knife is discarded. I have never heard of sharpness surviving if the knife is destroyed, so how can it be admitted that the soul can remain if the body is annihilated?
