Key passages
“Men had indeed an idea that there must be a “law of least action,” before they knew exactly how it ran. (Here, as always, the a priori certain proves to be something purely logical.)”
People intuitively believed in a 'law of least action' before its precise formulation, and this a priori certainty is always a matter of logic, not empirical fact.
Wittgenstein uses the law of least action to demonstrate that a priori certainty is logical in nature.
