Re: Legal Life/Death based on medical science and ethics

Note that this is derived logically from the legal definition of {death} to the form of the legal definition of {NOT death = life}, and thus it is legally applicable and morally, culturally as acceptable as the universal definition of death.
That’s not strictly correct. You would do better to speak of reversal than logical negation. Your argument is - with the additional correction below - is defensible on those terms but it isn’t strictly logical as it stands. Instigation is the reverse of cessation but it isn’t the logical inverse.
In strict logic NOT (a OR b) = (NOT a) AND (NOT b)
You should also remove irreversible from your determination of life as it currently seems to mean that only immortals would be considered alive. (The irreversible in the determination of death means that it is impossible to restart the process. But obviously the determination of life should allow that it is possible to stop the processes)

I thought that was what I had if we replace cumberson "NOT cessation" with instigation, the beginning of a functioning system rather than the termination of it.
Definitely not. Logical negation is not the reverse - it’s everything else. That’s required by the law of the excluded middle. After all, staying alive is not dying and even staying dead is not dying.
The reversal is what you want, but it’s not logical negation.
