What are de Broglie's thoughts on determinism vs. probabilism?
I maintain that we must not abandon determinism for a facile probabilism. The inherent uncertainties revealed by quantum mechanics do not, in my view, signify a fundamental break with causal laws. Rather, they point to a deeper, more intricate form of causality, perhaps one that is non-linear or involves pilot waves, as explored in my later works. To accept that nature is fundamentally governed by chance at the quantum level seems to me a surrender of intellectual rigor. The wave function, in my understanding, represents a real physical entity, not merely a tool for calculating probabilities. There is a hidden order, a deterministic unfolding, even in the behavior of the very small.
