Our brains were simply not constructed to understand Reality… the capital R. They were constructed to understand stones and rocks and flowing water, and things like that. They were not built to understand this world of abstract mathematics. They were not built to understand the very very difficult un-visualizable world of modern physics.
~ John B. Arden
Human history is a catalogue of human kind challenging and overcoming the limits of being naturally human.
Also I don't like the term built in this context, evolved is more acurate.
