It is difficult to say with certainty how Baruch Spinoza, a 17th-century philosopher, would have approached the reconciliation of Pythagoreanism with quantum theory. However, given Spinoza's rationalist and pantheistic views, it is unlikely that he would have seen a direct connection between Pythagoreanism and quantum theory.
Pythagoreanism is an ancient philosophical and mystical tradition that emphasized the significance of numbers, harmony, and mathematical relationships in understanding the nature of reality. It attributed profound metaphysical meaning to numbers and geometric forms. While Pythagoreanism influenced various areas of thought, including mathematics and cosmology, its concepts and methods differ significantly from the scientific framework of quantum theory.
Quantum theory, on the other hand, is a modern scientific framework that describes the behavior of matter and energy at the microscopic level. It is based on principles such as wave-particle duality, quantization of energy, and probabilistic interpretations. Quantum theory relies on mathematical formalisms and experimental evidence to make predictions about the behavior of quantum systems, rather than attributing metaphysical or mystical significance to numbers or geometric forms.
Considering Spinoza's emphasis on reason and his inclination towards a rationalist understanding of the world, he might have viewed Pythagoreanism as more of a philosophical or mystical tradition rather than a scientific one. While he might have appreciated the philosophical and aesthetic aspects of Pythagoreanism, it is unlikely that he would have sought a direct reconciliation between Pythagorean ideas and the scientific principles of quantum theory.
