I promised a rebuttal and here we go
There are people with severe communication problems, that does not mean they don't have knowledge
Indeed, it also means that they don't necessarily have knowledge.
For me to know you have knowledge you need to express it.
A mechanical automobile
That can be a motorcycle, a scooter. It does not have to be a car. Try again
And yet, you would surely leap to safety if one of these possible "illusions" was barreling towards you.
That is because I belive in the illusion.
Not true. Even if the car does not exist, you have knowledge of the illusion. Which is still knowledge.
Rather, I have knowledge that I have no knowledge.
Of course it is subjective. It is a feeling. That has nothing to do with the question though... whatever you label love, you have knowledge of it occuring when it does so. Even if we have two completely opposite meaning of love when it is experienced, we know that the underlying feeling we refer to with the word "love" has occured.
You are assuming that what you felt before that you called love, has happend again. You are also assuming that you are the same person that experienced that love before. You are also assuming that what has happened to you is actually love.
So there is no knowledge there; only doubt.
For the person who labels the release of endorphins love, he knows every time that it does so love has occured. Whatever is meant by the label "love" there is knowledge that it has occured.
Well there is no way for a person to subjectively count the no of endorphins released to know love has happened. Nor is there anyway to know that the release of endorphins has any connection to the feeling of 'love' ?
As I said before, you are too hung up on words. Language is a convention of symbols and their meanings, so yes, you go back until you find a word you share a common understanding on, and then work back until you understand what the other meant. I do this all the time with words I have not encountered before.
Even words we know we can't give an account of. When you ask me what does fast mean, I respond it means quick. Then you ask me what quick means, I respond it means rapid and so on.
Have you heard of deconstructionism?
It is knowledge of present language convention. Even that is knowledge. Knowing that love means x to Person A is a type of knowledge.
Deconstructionism applies again.
Sure one can, for oneself. I cannot say what constitutes love for you(unless you convey that to me), but I can for myself.
I can be sure for myself what it means.
Or maybe you don't know the meaning either? Maybe the meaning changes every moment. Can you be 100% you know the meaning of love? I don't think so.
One cannot even be sure that they are the same person the next moment...
I'm saying one knows what love means to one's self. Thus I know what love means to me. You know what it means to you.
Same as above.
While each instance of the feeling related by the word "love" is unique, they share a general enough base for there to be a common understanding, so that when I say love, even if you can't be 100% sure that I am refering to the same thing, most people can understand what I am trying to convey.
There cannot be a common understanding. Everybodies feelings are private. You have no idea what love means to me, I have no idea what love means to you. Nor can I, Suraj, know what love
really means to me.
I'd have to know what Krisna meant by love, but for myself it is untrue, as I have felt the love of family and God.
Krishna means that this wordly plane, no matter how good it can get, is a realm of suffering. The real happiness is when one is liberated and does not have to come back here. So anything we call love or happiness here is really just pain.
Just as one who self mutilates convines themselves it is pleasure, but really it is just pain, likewise we mistake pleasure in this world for pain.
Not much, I find it similar to saying "You can solve all mathematical equations or you can solve none", or "You are a Superstar NFL player or you do not know how to play at all". Of course there are middle grounds, there are middle grounds in almost everything...
It's about knowledge. The correct way of representing it would be you either know all of maths or you know none of it. There is no room for any middle ground as Godel proves. All other systems of maths are incomplete, they do not produce any real knowledge. The same applies to all systems of logic; all scientific systems.
You really should read Hume as well. We know nothing. It is true. We simply have to be humble enough to accept that.
The seeker who seeks without claiming knowledge will find what they seek, else you will find only what you think about what you are seeking, but never the thing itself.
