Like most of the stuff I’ve read in the book, I’ve looked for this quote all over the place. Kept thinking it was in Part IV. No, no, it’s right in the beginning.
… the true concept of the reality of God is reasonable to logic, plausible to philosophy, essential to religion, and indispensable to any hope of personality survival. (24.6) 1:2.8
In my mind, the “true concept of the reality of God” is roughly analogous to the “truth”, when used broadly. While some thing may be any of these things individually, in order to rise to the level of the “truth”, it needs to meet all these tests. It’s like the ultimate Venn Diagram.
