All we know of justice or goodness is what we find in our consciences. But we are dependent creatures. Our consciences themselves were given by God, and His law is written upon them. So when we make judgments, we can only use the tools that He Himself has provided.
This assertion is in need of support.
If the standard of justice is not in God, it is nowhere.
Who says? First, you haven't established that God is the standard, and you certainly haven't responded to the issues that raises (as discussed above). Second, wellbeing is not "nowhere," and we at least have some way of gleaning the effect our actions have on the wellbeing of others.
When you reason all the way back to your ultimate standard—and no one else in this thread has done that—circularity or self-referencing may well be unavoidable. Cornelius Van Til argued that all reasoning is ultimately circular. And every logical argument is based on unproven assumptions, as no one disputed earlier in this thread.
Are you talking about the basic assumptions we all make with regard to logic? We need to assume the rules of logic if we are to be
logical. We accept these rules simply because we must if we are to think
logically; that is, to form logically coherent thoughts
. And we need to be able to do that if we are to examine claims logically, including the claims of your religion.
Everyone must then choose his circularity, so to speak. I will go with the self-evident God who is perfect in justice.
First, it's clearly not self-evident. If it were, then there would no need to ask you support your claims. Second, given what you have stated earlier, saying that God "is perfect in justice" would be akin to saying "God is perfect in himself." I raised this point
earlier and referenced FrumiousBandersnatch's
post on the same topic. You have yet to engage with this point.
Amoral chemical reactions in the brain in response to amoral stimuli do not provide a meaningful standard of justice, only an amoral feeling. Provine, Rosenberg, and Nietzsche, who as atheists worked out the implications of their atheism, would presumably agree.
It's clear that you cherrypicked those atheists that you think agree with you. I don't know much about Provine and Rosenberg, but Nietzsche certainly does not agree with you. Nietzsche saw Christianity as giving rise to nihilism. How might Christianity lead one to nihilism?
By convincing its adherents that life must be imbued with theological significance or else it is meaningless? By encouraging its adherents to view this life as a sloppy impromptu dress rehearsal for the next, which promises to be so beautiful that this world is ugly by comparison? By transforming moral statements into religious opinions, anchored to an unstable theological foundation on the verge of a devastating collapse?
Provine, Rosenberg, and Nietzsche, who as atheists worked out the implications of their atheism, would presumably agree.
It bears repeating:
As noted
earlier, you haven't shown that atheism leads to absurdity, nor have you shown that theism alleviates this purported absurdity. In short, your core claims remain unfounded.
