A visitor to my website sent me the following question:
I somehow came across your validation text of the primacy of existence, and found it very enlightening and interesting to read. However, it got me thinking of a quantum mechanics experiment I have heard about, the Double Slit Experiment. Have you heard of it? I have studied neither philosophy nor physics but am greatly interested in both, and my intuition told me that the double slit experiment contradicts the primacy of existence. Since you seem very adept at organising thoughts and arguing theories as these, I felt like asking you what you think of this matter.
