I will post a response and my reply to it to get my point across:
Response: But you can experience greatness, a sense of life being good and worth living, and you can experience the beauty and transcendence from this life even without your feelings of pleasure.
My Reply: No, you can't. Our expressions reflect our sense of good value, worth, beauty, greatness, and transcendence in life. If I were to look at something beautiful, then the only mindstate that I can achieve from that and the only expressive tone that can be achieved would be some bland, neutral, and dead robotic-like tone such as: "Gee, this is something beautiful and great." But if I were to have my feelings of pleasure right now, then my expression would be: "Wow, this is something great and beautiful!" Even if I were to express myself with the latter quote without my feelings of pleasure, that expression would be faked and would still have the mindset (tonality) of the former quote. So this is the reason why you cannot have any sense of good value, meaning, or worth in your life without your feelings of pleasure since it would all still have that same robotic and dead tonality to it. People are only fooling themselves into thinking that their expressions and thoughts do have a life-filled genuine expression to them without their feelings of pleasure. The fact is, it is all nothing more than the "thinking" experience. All our experiences and such in life without our feelings of pleasure or suffering would all have that robotic-like and dead tonality to it since it is only our feelings of pleasure that give us and our lives a life-filled tonality. They are the only things that give us and our lives a sense of greatness, beauty, good value, and worth in life. Our feelings are the only things that genuinely define our lives as good or bad and are the only things that give us a sense of either good value (feelings of pleasure) or bad value (feelings of suffering).
