Empiricism is basically the art of inference based on outward appearance in different contexts.
I’d argue we learn everything based on appearance. You have to do more than just observe things superficially and take context into account, but for something to be measurable it has to have some sort of outward appearance, whether that be direct, as in something you can see with your naked eye, or indirect, as in something we need to measure through some other instrument.
