Thank you for your kind praise. Apologies for not responding earlier; I was busy finishing my next book.

I've been very happy to facilitate in small ways your articles on your concept of truth units. I find it a very promising way for us to look deeper into language without the pitfalls that encumber most approaches. What you write here in your example of the pencil is Wittgenstein's comments that some things cannot be said but can only be shown. Ultimately, we need to show each other the object of our thoughts and words. He was open to the idea that, as you say, we need to compare (show) our experiences to be able to understand what we mean. Because, as you say, we are testing what each other says using our own experiences as a guide, because we use our own experiences to justify our beliefs. That's where I think the realization that some things can only be shown is important.

Yes, it was Russell who invented the concept of atomic truths.
