Fundamentally, germ theory contains a grain of truth (viruses and bacteria are found where there's illness) but the relationship is much less causal than we think (a virus does not directly cause illness, instead its presence is an opportunity to enter a disease process which the person and their body accepts or rejects).

How did the Black Plague kill 1/3 of people? Why not everyone? Why did it not affect many who were directly exposed and cared for those who were infected and ended up dead?

Superior immune systems? Determinism? Genes? Or does a person's mental state play a role here?

How is the universe constructed? Does the tail wag the dog (matter creates consciousness), or does the dog wag the tail (consciousness creates matter)?
