Pearl's paper is a solid generalization on logical reasoning and intelligence, but we have to be wary that even us, humans, aren't perfect at generalization and regularization. Without going too meta, we have to contemplate whether logical reasoning causes human level intelligence or it's a mere effect of a complex statistical phenomenon. It may be the case that a human-level AI system will contain all seven pillars of causal reason, but it does not mean that these reasoning were specifically programmed into the AI. A similar example of this human over-regularization can be found speech technology, linguists have generalized 50~60 phonemes in English speech, though in real life speech, there are magnitudes more phonemes in play, if we force our speech recognition systems to classify speech into 60 phonemes, we miss out on important details. This is why end to end systems such as WaveNet is so much better than older systems, because when we ditch our over-regularized concept, it can learn more freely.

> we have to contemplate whether logical reasoning causes human level intelligence Human level _logical_ reasoning has not existed for long time and can't be the cause of human level intelligence because it is very little used in practice. Natural logic has existed little over 2000 years among subset of intellectuals as a method for reasoning. Natural reasoning is one of the causes of human level intelligence It's basically just a bag of heuristic rules used in qualitative, action-change and taxonomical reasoning. There is no evidence that deduction has significant role in commonsense reasoning.

As a matter of fact the first logical system heavily used induction, not the duction, to extend regularity over unknown topics instead of exploring the unknowns systematically and deriving the regularities out of the experiments.
