Actually, it’s a quote from G.K. Chesterton’s Orthodoxy:
“Every man has forgotten who he is. One may understand the cosmos, but never the ego; the self is more distant than any star. Thou shalt love the Lord thy God; but thou shalt no know thyself. We are all under the same mental calamity; we have forgotten our names. We have all forgotten what we really are. All that we call common sense and rationality and practicality and positivism only means that for certain dead levels of our life we forget that we have forgotten. All that we call spirit and art and ecstasy only means that for one awful instant we remember that we forget.”
I love this guy. Besides the fact that I often find myself reading with a British accent, I often find myself laughing quietly (more of a snicker, really) at the way he strings paradox and irony from daily life into a philosophical treatise on Christianity.
so, read that passage again. And then, go find a copy of this book to read. Accept that you may not understand every sentence as you read it, but keep reading. Chesterton’s an author you ingest as a whole instead of piece by piece. At least the first time you read it.
