My proofs for Islam

[Mystic]

That destroys the meaning of all actions, it destroys everything we hold dear.

False.  People create their own meaning all the time.

They create meaning but with belief that there is an objective value to who they are.  Take away that belief, and nothing is left.

It may or may not be properly basic, belief that we have an objective value and reality, I am not sure. I will have to reflect if it can be reduced.

It's like asking "Why love?" - well love itself knows the answer, and nothing else but love can justify it.

I will reflect and get back to you if it can be reduced further or all we can do is appeal to facts we know we don't believe and hence show we believe we have objective value by contradiction or reductio absurdum.
