Hmmm. They are written in a loose leaf notebook in his hand. My opinion is that Spence recognized the brilliance of the entries, they meant something to him, and took the time to compile them. He had difficulty expressing himself. But that does not mean that he didn't understand things. And that is yet another lesson that Spence can teach us, that certain mental challenges do not pre-empt other mental geniouses and geniouses of the heart. Your question prompted for Spence to affect me again, teaching me yet another significant lesson of life. He still lives in the effects that he has had on others. And so that his life can touch you and others as it touched me and all who knew him, is why I am delivering these thoughts. I must admit, answering your question brought a tear to my eye. Thank you for the question. It helped to bring this fine friend back to life.
