One might say that I am an initiate of a certain degree in the church of physical sciences. I have a bachelor’s degree and a doctorate from a kosher university, I was at one time a member of two professional learned societies and they even let me teach for a decade or so. I have an albeit rusty context of how UK academia works. I was able to write and secure a quantum optics patent whilst “retired” and well away from the hurly burly. There is no chance that I could teach at undergraduate level these days, I might still be able to do some fancy-schmancy laser experiments. Were I to encounter someone from that world I could at least have a go at conversation, even though I no longer share the ambition or goals. There would be at least a partial context in common.

That background was held in suspicion on various courses such as foundation shamanic and I Ching. When I stayed up all night and kept the camp fire going in the middle of a wood, the would be shamans accepted me more freely. I was perhaps more rigorous and less angel-reiki-fairy. Perhaps more American Indian than they from the home counties. If you have never been in a drumming circle you have no idea what goes on there.

As a thought experiment imagine me sitting down with a university professor who had a reputation for top end molecular spectroscopy and the use of ab initio quantum calculations to elucidate intermolecular interactions and bonding. This was something that we once shared.

“Well, it has been a long while. From time to time, I see your articles. Since we last met at lot has happened to me. I have learned of a number of my previous incarnations and all the evidence points at me being a three pronged dreaming nagal of the elephant dreaming class, I am a dreamer by prediction and have been doubly severed.”

I suspect that I would have lost the professor in and around the previous incarnations bit. He was a Christian and fairly devout. It would be impossible to convey to this intelligent man what the last sentence means. I remember him as being philosophical and open minded. He could take it at face value being polite.

But where would you begin? If you read these books about Toltecs, I can visit you again in a couple of years and try to explain.

The chances are that there would be not much purpose in trying to explain. That sentence is of a different world and next to impossible to verbally contextualize. His eyes might glaze over.

So, I might change the subject and say I really enjoyed his paper on mass resolved rotational coherence stimulated Raman ion dip spectroscopy for large molecules without an absorption transition dipole moment. I would be back in context and even though I am rusty we could have an intelligent conversation which would be above the heads of many people who have never even heard of these things. I would be talking arcane chemical physics with a world expert. I still have residual arcane spectroscopy knowledge.

There are some conversations which are impossible if there is no shared context. Two ships might pass in the night oblivious of each other. Sure in their world, convinced of their reality and unaware that there are more than one reality.
