“I set out on my travels knowing, or thinking I knew, how men should live,
how be governed, how educated, what they should believe.
I had my views on every activity of life.
Now, on my return, I find myself without any of
these pleasing certainties . . .
The better you understand the significance of any question, the more difficult it becomes to answer it.
Those who attach a high importance to their own opinion should stay at home.
When one is traveling, convictions are mislaid as easily as spectacles, but unlike spectacles, they are not easily replaced.”
