For empirical facts, it seems obvious that causality requires a time flow for the concept to make sense: A causes B implies that A happened before B.
Is it ever possible to have a causal relationship without a flow of time? Presumably this is impossible for empirical facts, as an effect preceding a cause goes against the laws of physics. Is this always true?
But what about relations of ideas? Is it possible to have a causal relationship between two ideas?
Colloquially we often speak of ideas having causal relationships:
- Equation B is a consequence of theorem A.
- Proposition Y is true because of proportion X.
Are these true causal relationships? Or is it merely us projecting our temporal thought processes onto the ideas and propositions we are analyzing and hence seeing causality where there is none? Can relations of ideas have causal relationships?
