I say:
meaning, why should its relation to His power not be
reasonable?
All this is sophistical and wrong. The philosophers do not deny that a
thing becomes non-existent when a destroying agent destroys it; they only
say that the destroying act does not attach itself to it, in so far as the thing
becomes non-existent, but in so far as it changes from actual being to
potential being, and non-existence results from this change, and it is in
this way that non-existence is related to the agent. But it does not follow
from the fact that its non-existence occurs after the act of the agent that
the agent performs it primarily and essentially. For when it was conceded
to Ghazali during the discussion of this problem that the non-existence of
the corrupting thing will necessarily occur after the act of the corrupting
agent, he drew the conclusion that its non-existence would follow
essentially and primarily from the act, but this is impossible. For the
agent’s act does not attach itself to its non-existence in so far as it is nonexistent,
i.e. primarily and essentially. And therefore , if the perceptible
existences were simple, they could neither be generated nor destroyed
except through the act of the agent being attached to their nonexistence
essentially and primarily. But the act of the agent is only attached to nonexistence
accidentally and secondarily through its changing the object
from actual existence into another form of existence in an act followed by
non-existence, as from the change of a fire into air there follows the nonexistence
of the fire. This is the philosophical theory of existence and nonexistence.
Ghazali says:
And what is the difference between you and the man who
denies absolutely that non-existence can occur to accidents
and forms, and who says that non-existence is nothing at all
and asks how then it could occur and be called an
occurrence and a new event? But no doubt non-existence
can be represented as occurring to the accidents, and to
speak of it as occurring has a sense whether you call it
something real or not. And the relation of this occurrence,
