▽The "brain in a vat" is a hypothesis elaborated by Hilary Putnam in his 1981 book "Reason, Truth, and History".
"A man (you can assume it is yourself) was operated on by an evil scientist. His brain was cut off from his body and placed in a tank containing a nutrient solution to keep the brain alive. The nerve endings of the brain were connected to a computer, and the computer transmitted information to the brain according to the program so that he could maintain the illusion that everything was completely normal. To him, it seemed that human beings , objects, and the sky still exist, and one's own movements and body sensations can be input. This brain can also be input or have its memory intercepted (the memory of the brain surgery is intercepted, and then various environments and daily life he may experience are input). He can even be input into a code and 'feel' that he is reading an interesting and absurd text here. "
The most basic question about this hypothesis is: "How can you guarantee that you are not in this dilemma?"△
If our love is based on memory, an illusory memory, or even an illusion. Then love for you can be preset, and it can also be rewritten.
If "love" is a feeling, and one day the feeling comes from an illusion, and you are deceived by the illusion, "How can you guarantee that you are not feeling this way?"
Idea: How can you guarantee that you are not in this kind of dilemma?
