It seems to me the reverse … love is more than a state, it is something we have or don’t have that brain and body know. To say that love is a “state” is to say that love really doesn’t exist or is unreal since it is just part of the state of the brain.
What instruments measure isn’t the brain, but what is in the brain at the time. And these instruments are measuring and determining what is in the brain at the time because of tell tale signs. An object reality is being measured … fear, love, anguish, courage and so on. Because when love is not there, then the instruments do not measure anything if looking for love. These objective “emotions” come and go and are fluid and not something that is fixed in the brain such as a “state” would call for.
Now you may say that scientists look at it “that a-away”, but that doesn’t mean that they are correct. We must look at things “outside” of the box or we miss important truth. What would be said as a state of the brain is merely a function of the brain to have thoughts which are objective “things” which then the brain and body respond to. These things … love, hate, fear … have object realities and are not apart of the brain itself. The brain can control these thoughts as it wills to make or not make.
What these instruments are measuring are the makings of the brain and not a part of the brain. This you might say is a fine point, but it really is not. Because one way says that the brain is in control and the other way says that the brain is controlled how ever subtle that may be.
