Reality contains not only evidence, but also the means (such as our minds, and our artefacts) of understanding it. There are mathematical symbols in physical reality. The fact that it is we who put them there does not make them any less physical. (Ch.3)

The first question we should face is: What is the aim of a physical theory? To this question diverse answers have been made, but all of them may be reduced to two main principles:
"A physical theory," certain logicians have replied, "has for its object the explanation of a group of laws experimentally established."
"A physical theory," other thinkers have said, "is an abstract system whose aim is to summarize and classify logically a group of experimental laws without claiming to explain these laws...
Now these two questions — Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? — do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics.
Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics...
Now, to make physical theories depend on metaphysics is surely not the way to let them enjoy the privilege of universal consent.Pierre Duhem
When I talk of reality, I am always thinking of essentials. Profundity is not located in some remote, inaccessible region. It is rooted in everyday life. That is what great thinkers have taught me, above all the philosophers of the Far East, for whom true wisdom — which I am far from achieving — is the conjunction of samsara (the ordinary world) and nirvana (profound reality). To achieve contact with reality is not to transport oneself elsewhere, it is not transcendence but thorough immersion in one's surroundings. A reality which is neither purely physical nor metaphysical, but both at once.
Antoni Tapies
Fundamental ideas play the most essential role in forming a physical theory. Books on physics are full of complicated mathematical formulae. But thought and ideas, not formulae, are the beginning of every physical theory. The ideas must later take the mathematical form of a quantitative theory, to make possible the comparison with experiment.
Albert Einstein
"To say that a thing is imaginary is not to dispose of it in the realm of mind, for the imagination, or the image making faculty, is a very important part of our mental functioning. An image formed by the imagination is a reality from the point of view of psychology; it is quite true that it has no physical existence, but are we going to limit reality to that which is material? We shall be far out of our reckoning if we do, for mental images are potent things, and although they do not actually exist on the physical plane, they influence it far more than most people suspect." --Dion Fortune, Spiritualism and Occultism
Dion Fortune
The physical carrier is overshadowed by a relation. The relation creates an overtone. The physical carrier is absorbed by this overtone. The overtone spontaneously transforms the means of creation into a spiritual reality. The mystery of creation is then revealed.
