Jesus Zamora Bonilla said this quote

The best ship, the best culture, the best knowledge, is the one which allows us to go farther, explore more territories or oceans of reality, and have the least damaging leaks possible.

~ Jesus Zamora Bonilla

Besides our eyes, skin and the other senses through which we receive the shadows of the exterior reality, we have a 'mental eye' (intelligence) with which we can perceive reality as it is.
