Your friend--despite his upcoming status as what you are calling a "brain sergeant," whatever that is, seems to be lacking a bit of information. One sign of foolishness is not knowing how much you don't know. This is what is called "sophomoric," ie. being only part way through ones basic education, but believing one is already hatched as a pro. Perhaps by the time this guy actually earns his degrees and works in the field for some years, he will have learned and understood more:

Recent brain scan technology has enabled studies of the timing of what is called "volition," or will, versus the timing of associated movement—in other words, studies of the timing of the experience ofdeciding to move versus actually doing so—which lead to the surprising result that the the neural preparations for moving occur prior to the experience of choosing, deciding, or willing
to move, perhaps even ten seconds earlier.

Your own dismissal of the entire field of psychology, and your unquestioning belief in what you imagine is "science" is beyond foolish, but I have neither the time nor the inclination to make the effort to explain why. Perhaps one of the Forum regulars would like to take a crack at it, or at some of the many other misapprehensions in your letter.

Be well.
