We see the world with but one set of eyes. For this reason, it can seem that we are doomed to a narrow prospective. As we learn, we form opinions, habits, and preferences. Part of this process is beneficial as we (hopefully) progress toward wisdom. The downside is that we become closed minded and overly opinionated.
The ability to completely shed our worldly biases and see the world at face value is probably unattainable. But we can take steps in that direction.
By travelling we expose ourselves to alternative worldviews. Through authentic contact with other cultures we can break through the confines of our personal understanding and discover the perspectives of our fellow man/woman.
