Relying on only what can be seen to inform you. We can never be sure of the the unseen, what people are thinking or the intangible and unseen systems so why risk the erroneous conclusions. What you see is what you get. It’s using the five senses because that’s what’s the most “real”. There isn’t much meaning beyond what we can see and what is actually happening. A conceptual identifies patterns but not beyond what we can see and what we can objectively know. Numbers, scientific reasoning is the highest form of logic, it is valid and quantifiable. Building systems of thought only in terms of what can be proven and building processes to cannonize that system.
