Re Physics, please correct me as required but in the way I use the phrase “first principles” here, Physics does not have any first principles.
Yes it does. They’re just so implicit in our intuition about how the world works that we don’t notice them. For example, consider all the implicit assumptions necessary for statements like “these two sticks have the same length” to be meaningful.

So, why does physics have no such first principles but economics does?
