Quantum Mechanics is not simply a mechanism for guessing things. It offers us a deep insight that the world is not as it appears to our senses. It is quantum mechanics that leads us to the conclusion that we may actually be living in a Holographic Universe. The idea the the the world around us indeed the entire universe is simply the projection of a deeper reality.
In his essay The Universe Anonymint draws our attention to the the holographic principle. Specifically the fascinating notion that when you combine the the holographic principle with the thermodynamic quantities of heat and mechanical work it is relatively straightforward to derive Newton’s classical equation of gravity.
These ideas are difficult to grasp and at this stage they remain theoretical physics. However, there are a growing number of scientist who are taking them very seriously.
I don't believe in the holographic principle, I actually think this belief is very close to theism, as Gödel said, the world is either a perfect order of god, or chaos. The difference is in the belief that infinity comes before entropy.
I have argued against atheism on three axes.
1) Metaphysically because the choice (in isolation) voids the existing moral structure rendering the decision itself morally incoherent.
2) Biologically because a sound moral structure is necessary for a healthy life and rejecting traditional structures appears to reduce health, happiness, and fertility.
3) Anthropologically because religion is a critical and perhaps primary mechanism for overcoming our species-specific upper limit to group size which is set by purely cognitive constraints.
While I would concede that nihilism is internally metaphysically coherent in that it is impossible to prove nihilism is false. It is likewise impossible to prove theism is false. My criticisms of atheism, however, do extend to nihilism.
You argued above that nihilism allows one to form a positive doctrine for re-evaluate of ones values and that the end of tradition that produces the possibility of new things to come. However, there is no reason to think the goals of progress and improving our value system and cannot be achieved from a framework of theism. With this in mind why choose a philosophical belief that is potentially unhealthy and detrimental to the progress we have made so far?
I think they will be achieved from a framework of theism, but in a slow way, that will leave behind piece by piece the spiritualism from theism, until it is reduced to the pure belief of transcendent perfection without content. That kind of theism would be compatible with nihilism and the two could coexists as mutually agnostic. The problem is that traditional theism brings spiritualism, and that spiritualism is just a more primitive type of thought, and that its bad when applied to knowledge, or morality. For example its hard to understand and artificially reconstruct the mind, if people think its an eternal substance completely separate from matter. Basically, I don't really care what anyone belives, as long as it doesn't determine knowledge, but because spiritualism practically always does, I'm against it.
