It is easy to misunderstand poets. It is easy to hang on a few words of a poem and misuse them. Huxley used the phrase “doors of perception” which Jim Morrison shortened further to “the Doors”. In fact the originator of the phrase was William Blake who wrote in the Marriage of Heaven and Hell
“If the doors of perception were cleansed everything would appear to man as it is, infinite,
For man has closed himself up, till he sees all things thro’ narrow chinks of his cavern.”
In doing so he built upon an idea of Plato’s in the Republic of men locked in a cave, seeing shadows and believing them to be true representations.
We all live in a world where what we see are mere shadows, through dirty doors, or opaque windows recognising little and understanding less.
