Here's what Copi says:
Copi [1953, 56] "Introduction to Logic"
"The fallacy of argumentum ad ignorantiam is illustrated by the argument
that there must be ghosts because no one has ever been able to prove that
there aren't any. The argumentum ad ignorantiam is committed whenever it
is argued that a propostion is true simply on the basis that it has not been
proved false, or that it is false because it has not been proved true."
Several important points here that illustrate how off the beam your
viewpoint has been.
1. Note the use of the term "must" "...there MUST be ghosts because no one
has ever been able to prove that there aren't any." Copi is talking about
definitive conclusions of proof based on ignorance or lack of proof to the
contrary.
2. Note the use of the term "argued." "....The argumentum ad ignorantiam
is committed whenever it is ARGUED that a proposition is true simply on the
basis that it has not been proved false..."
Copi does not include the notion of "might be/might not be" in his
definition. And he wisely notes that the Argument from ignorance must be an
ARGUMENT. It is not a statement, it is not a question. It is an argument.
Since your entire spew is based on the idea of "maybe's and might be's" and
since you presume that even a question or a statement can be an Argument
from ignorance, you're clearly WRONG.
