Question

Good evening!
1. How is it possible that animals discern causality, if causality is not empirical and is not learned from experience (since the most that can be learned is temporal and physical precedence)? Do they have a priori reasoning?
Seemingly, the answer is that they indeed do not discern the a priori logical principle of causality, but rather only respond based on Pavlovian conditioning. But about that, it is difficult for me: out of infinitely many possibilities, why are they conditioned דווקא in this way?
2. I would also be happy to ask: children are not born with the principle of causality, but learn it over time. If so, insofar as in their early childhood they are only conditioned (for example, when Mommy comes, they know they will eat, etc.), when and how do we come to discern the a priori principle?
3. Who says that we really do discern causality a priori? Maybe we are only conditioned, and simply define it in discourse in a useful way as a causal principle, but beyond that there is nothing at all?
Thank you very much!
