Philosophic profundity?
Seems to me that most of the quotes from Amadeu's book read by Gregorius sounded a bit superficial, or at least somewhat obvious, and not original at all.
We leave something of ourselves behind when we leave a place. We stay there, even though we go away. And there are things in us that we can find again only by going back there. We travel to ourselves when we go to a place. Now we have covered the stretch of our lives, no matter how brief it may have been.
Does this strike one as a baffling insight, which changes Gregorius' life? If so, the poor bugger must have had a boring, superficial life indeed.
Also, the quote is reminiscent of Anaïs Nin: “We don't see things as they are, we see them as we are.” Which, in my opinion, is very insightful.
