Although we have come a long way from relying on our five senses to perceive reality (e.g. infrared, ultrasound etc.), I believe we are still far from understanding the world in its most fundamental/true form.

Intuition, theories, models and big data are helpful tools in developing a more granular insight, but without judgement these tools make little sense on their own.

Limitation imposed by the structure of our languages and (rational/irrational) thinking in general (may be physiological?) make the task more difficult. On some level we have to be less human to understand the world... So tells me my intuition.
