Often times when I read a popular book on the New Physics, the author/scientist will describe the unification of Einstein’s General Relativity theory with Quantum Mechanics as the “Holy Grail” of physics.
In other words, scientists are quite willing to use a metaphor as a rational and appropriate approach to explanation. In this case, the “Holy Grail” is not simply used to communicate the idea of a physical drinking cup but something corresponding to a higher level drinking cup—a psychical drinking cup.
The human mind “thirsts for truth.” The Holy Grail in scientific usage, therefore, represents something containing deeper knowledge—a deeper theory or framework about reality. What fascinates me about scientists using such a metaphor is that it is instinctive and its meaning is both rarefied and instantaneous.
Why should making an analogy between physical and mental terms ever work at all? What could these two distinct (and non-continuous) worlds have in common?
While most scientists indeed see metaphor as sloppy science, Emanuel Swedenborg offered lots of evidence that this symbolic language is quite precise. He called this language of metaphor (and allegory) the science of correspondences. This multi-leveled language is objectively scientific because it contains the same top-down patterning principles found within the causal processes and architecture of the universe—from dynamic non-local first principles to inert and measureable physical matter. Furthermore, he used this evidence to demonstrate how God’s Holy Word was written in this same multi-leveled symbolic language. For instance, the cup used by the Lord during the Last Supper represents a sharing of deeper knowledge with His Disciples.
So scientists have used this symbolic language in the same way an inspired theologian would. My book Proving God offers further insights to show how the Holy Grail for science is the same Holy Grail for theologians.
