Journey of the Mind

From September 8th Reading:
A line from pg 99's description of Petrarch's essay particularly struck me "Francesco Petrarch, climbed up a mountain in southern France simply because it was there." It reminded me of art for art's sake, which I've found really relevant in many of the readings that I've been doing in this class, and in other classes.
Petrarch took journeys of the mind and it is questioned if a journey of the mind is less significant. I find a journey of the mind to be entirely MORE significant because it uses the imagination, something intangible, something personal. Something that no one else can truly see. That is why it becomes much more fascinating to describe, because no one else can simply walk up to it and perceive it themselves. They rely solely on the person who invented it. Our minds are really all that we know. Even with material journeys, they don't exist to us unless we see or hear about them. I've been wondering for quite awhile about the mind and existence. Is something there just because we think it? Do we invent everything that we see? Nothing exists to US unless we are aware of it. I could talk in circles for much longer but I think I'll just let you come to your own conclusions.
