I haven’t had to teach basic logic 101 for years. Unfortunately, it is now obviously necessary.
When one analyzes a syllogism one breaks it up into soundness, validity and truth.

“Soundness” means that the premises are true and the argument is valid. If the argument is sound then the conclusion must be true.
“Validity” means that the form of the argument is correct. The truth or falseness of the premise does not matter.
For example, the syllogism,
1. All Martians eat snakes.
2. Bob is a Martian.
3. Therefore, Bob eats snakes.
, is valid.
The meaning of “truth” is obvious. “All Martians eat snakes” and “Bob is a Martian” are not true.
1. Cause always precedes effect.
2. Consciousness of a thought cannot precede thinking it.
3. Therefore, consciousness cannot cause thoughts.
Is obviously valid. 3 follows from 1 and 2.
The only thing left to do is see if the premises 1 and 2 are true. Premise 1 is obviously true. However, Spheres has a problem with premise 2. Since the argument is valid and premise 1 is obviously true, if premise 2 is true then the conclusion (that consciousness cannot cause thoughts) must be true.
Let’s investigate if premise 2 (that one cannot be conscious of a thought before one thinks it) is true. It seems obvious to me that one cannot be conscious of a thought before one thinks it. However, Spheres thinks that it is a false premise!
Sphere’s objection? That I have not defined the terms “consciousness” and “thoughts”. I assumed that everyone knows the conventional definitions * and are not confused when one says “consciousness” or “thoughts”. However, I also accepted Dennett’s unconventional definitions, that “consciousness” and “thoughts” are and only are brain states.

Perhaps an analogy will help. The image on your computer screen is the top level. Suppose it is attached to a monitor that “recognizes” the color blue. When the screen turns blue it sends a command to the computer hardware that makes the screen turn red.
True, the color blue on the screen facilitates the screen becoming red. However, the blue image on the screen was completely determined by the computer hardware (bottom level). I do not see how that is an example of free will.
If Spheres disagrees with the conventional definitions ( of “consciousness” and “thoughts”) and also rejects the unconventional definitions ( Dennett), I wish he would post his definitions of “consciousness” and “thoughts”!!
