1. Tom does not literally have a degree as a Ph. D./doctor of philosophy. Tom completed the work required to receive a doctorate as in taking the courses, passing them with a high grade level and taking the comprehensive tests given at the end as required as a near final stage. This is as I understand it. At this point as I understand things, he ran out of money to stay at the university so started working for a defense contractor. It is my general understanding that he started working with Bob Monroe at this time and putting all of this together, he never got around to completing the last stage required to obtain a Ph. D. which is to get your research finalized into a form as a dissertation that all of your supervisory committee will sign off on as a completed work. This is a major project in itself and nearly impossible to complete if you are not resident on campus. Most doctoral students who have to leave campus to work never get this final stage to get the magic piece of paper once they have to leave campus and start working to put food on the table.
I faced this problem myself but was able to do it as I was working for my father at his company and was given the leeway necessary to travel back to campus as needed and shepherd my dissertation through the last of the process of jumping all of the hurdles that are demanded to be jumped. So Tom has worked at a Ph. D. level for decades but does not have the magic piece of paper while I have the magic piece of paper but never worked at a Ph. D. level for money. In simple terms, Tom does not actually have a Doctorate for the reasons as described above.
2. I understand there to be 400+ and increasing videos in Tom's YouTube channel and in other sources on the Internet. If you want more accurate information than that, you can probably get a definitive answer from Tom's Events web site which is managed by Donna and Keith. Here is the link:
https://www.mbtevents.com/home.html You might look near the top of the Index page of the board to find links to basically all of the rest to Tom Campbell's world.
3. Lastly consciousness is a self modifying information system. The system consists of information and information is all that ultimately exists. This is pretty much the formal description but Tom might have a more definitive one. Do you want me to try to find out or is this sufficient?
