Perhaps travel cannot prevent bigotry, but by demonstrating that all peoples cry, laugh, eat, worry, and die, it can introduce the idea that if we try and understand each other, we may even become friends.
In all the languages in the world, there is the same proverb: "What the eyes don't see, the heart doesn't grieve over." Well, I say that there isn't an ounce of truth in it. The further off they are, the closer to the heart are all those feelings that we try to repress and forget.
There has fallen a splendid tear
From the passion-flower at the gate.
She is coming, my dove, my dear;
She is coming, my life, my fate;
The red rose cries, "She is near, she is near;"
And the white rose weeps, "She is late;"
The larkspur listens, "I hear; I hear;"
And the lily whispers, "I wait."
