Emotions are a sense like sight and hearing Your language is difficult to interpret but what you seem to be saying is that sensations themselves, whether good or bad, do not add sufficient meaning to our lives. You write: "sensations do not allow you to perceive any sufficient quality of good or bad value in your life at all". When you say "value in your life," you essentially mean meaning, right?
Most would agree that modernity has shifted the world towards a more materialistic mindset, that we're currently trapped in the iron cage of rationalization, and there's something of a cultural void when it comes to meaning in our lives. So we may be on the same page so far. There's a need that you attempt to address.
You go on to say that being in a "horrible miserable state, then that scent [of a rose] would not give me much awareness of good value in my life at all. It would only give me an awareness (perception) that is very slim." So the question is how do we get out of this miserable state. We know that pleasant sensation is too slim. I think even the illustrious pioneer in meaning Viktor Frankl would agree with this assessment so far.
From your previous comments, I glean your proposal to be that developing positive emotions is a way out of this miserable state and even go so far as to suggest that these positive emotions are objective perception, and then go even further by adding a quasi-spiritual quality to these positive emotions.
I can see some truth to this in that we can take an active part in how we experience emotion, and perhaps change them, with good result. For example, it's been suggested by researchers that reframing 'nervousness' to 'excitement' can change a potentially unpleasant and poor performing experience to a pleasant and high performing experience. Regarding whatever induced the arousal as a challenge rather than a threat changes the way our body prepares itself. If our mind predicts injury it will prepare for injury, sacrificing performance. If our mind predicts a need for heightened performance our body will prepare for that and our performance will be enhanced.
The scent of a rose may be too slim an experience to add meaning to our lives, but seeing the world through rose colored glasses may be too slim as well. Emotions are not a sense, they're only the tint of our lenses.
