"The fact of the existence of two theories [causal and acausal] that contradict each other in Jung … corresponds psychologically to the vascillation … - Wolfgang Pauli

When one analyzes the pre-conscious step to concepts, one always finds ideas which consist of "symbolic images." The first step to thinking is a painted vision of these inner pictures whose origin cannot be reduced only and firstly to the sensual perception but which are produced by an 'instinct to imagining' and which are re-produced by different individuals independently, i.e. collectively... But the archaic image is also the necessary predisposition and the source of a scientific attitude. To a total recognition belong also those images out of which have grown the rational concepts.

Later, however, I came to recognize the objective nature of these dreams or fantasies … Thus it was that I gradually came to acknowledge that such fantasies or dreams are neither meaningless nor purely arbitrary but rather convey a sort of "second meaning" of the terms applied.

There are many examples in physics showing that higher precision revealed new phenomena, inspired new ideas, or confirmed or dethroned well-established theories.
