Should you want your statements to stand, it may be advisable not to knock them down as you try to keep them upright.Quote from trainr:
... which is to say you cannot refute it. At least, you haven't done so.
You could at least try, eh?
All you have to do, if you're up to the challenge, is prove that the domain of effects a) is always a function of cause, or b) is never a function of cause.
I seriously doubt you can do it. But, hey, give it a whirl.
If you can't prove one of the two, my original statement stands.
You demonstrated that to decide what exists, requires you put the onus imperatively on what exists. Then you destroyed your own statement ( in the same sentence no less), by arguing the onus must be on proving what does not exist.
You also stated ... "all effects have causes except the ultimate cause." ...
So far your next statement largely says, effects have causes - but an ultimate cause doesn't have a cause .
Now not only has your previous statement contradicted itself, that one doesn't make sense
Then you go on on to your "cause and effect challenge" above, which is no longer to do with onus or what exists. It is to do with whether two things which you have already taken to exist (cause and effect) are - or are not - a function of each other.
I don't think your confusions are helping your statements or your arguments any.
