I prefer for 'my world' to have the highest certification of being a faithful representation of the exterior world.
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.
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.
