One line might appear quickly to a person who picked up the book and started flicking through the pages. It’s in the introduction and is these words. “If the doors of perception were cleansed everything would appear to man as it is: infinite.”The verse is well known partly because “The Doors” rock band, lead by Jim Morrison, was named after it. Aldous Huxley also called his examination of psychedelic experiences, “The Doors of Perception”. But the association with various kinds of exceptional ecstasy is misleading, I think.Blake undoubtedly had what would be for many unusual experiences. I already mentioned the angels in the tree. But he wanted to understand why such perceptions were uncommon, even doubted, in the modern world and his diagnosis was to do with the modern sense of who we think we are as human beings.In the decades before he was working, thinkers like Adam Smith and John Locke had argued that human beings are essentially autonomous agencies. For instance, the separation of bodies and minds, as if the psychological were utterly different from the physical, had become a widespread assumption. That led to the sense that human beings were confined to their bodies, as opposed to sharing in a wider pulse of life that flows through all things. Then, that wider pulse started itself to be doubted. For instance, the word “nihilism” was coined during Blake’s lifetime. In other words, our perception of things has been closed in by doors that imprison us. Blake sought to cleanse that philosophy so that the doors could become windows once more. Then, he said, people would start to experience life as boundless – unconfined, free. We would see a world in a grain of sand and a heaven in a wild flower. Everything finite would speak of the infinite, everything temporal could carry echoes of eternity.With that renewed perception, Blake believed, many of the struggles and conflicts of his day and ours would be eased. People might learn to trust life again and to be less afraid. I think Blake was right. We need that deep analysis of our times to address the challenges fully.So my hope is that people can discover a friend for life in Blake. He writes other lines that you can revisit almost every day, as a kind of practice, and feel how they work on the psyche to expand perception. Take these:

“He who binds to himself the joy / Does the winged life destroy. / But he who kisses the joy as it flies / Lives in Eternity’s sunrise.”

How can we trust life so as to give ourselves to it, rather than working to secure our patch of land or possess more and more things? How can we look to the imagination, alongside reason and evidence, and see that it connects us with the natural world and the cosmos?These are not trivial things to ask since they invite nothing less than a transformation of who we are. But then again, I feel we live in a period of great challenges that can welcome great responses. William Blake is a guide I want to commend wholeheartedly to others!
