This question has been stuck on my mind since last night.
If dopamine signals were (somehow) artificially triggered during negative actions in someones brain through some machine or something, could the brain defy logic and reasoning and perceive those actions as positive?
Of course. Your personality and consciousness are entirely defined by three things: Your memories, your current surroundings, and the current chemical state of your brain/body. Changing any of those will change your logic and reasoning because reasoning in a vacuum is something only computers do.
For examples of changes that would drastically alter the thought process of even the most stoic, rational person, here:
Any of these things will immediately demonstrate that we are not computers or logic machines.
TBF if you change the chemistry of your circuit boards the computer won’t work the same either.
Same with removing stored settings files.
Honestly, probably same after a certain amount of time with the centipede coffin.
