I was 17 years old in 1961. I was still wet behind the ears, fresh off the farm and somewhat surprised to find myself sitting in a college philosophy class populated mainly by older students. I am not sure why I registered for it, perhaps it just sounded interesting. My personal philosophy at the time could be simply described as, what happens, happens. But, when the professor said, “The chair you are sitting on does not exist,” What?? My eyebrows hit my hairline, my brain rolled over and I knew I was in trouble.
