You seem to have quite a gift for confusing yourself. The notion that because knowledge in the form of wisdom or truth in a more philosophical sense is discovered or reacquired by the collapse of the delusional state of duality via the removal of unconscious assumptions, biases we were conditioned to believe takes us back to our original not-programmed state, but this time permanently because our capacity to be programmed has been removed. Thus we can become who we really are and have been for thousands of years, what every enlightened person has experienced over and over since before history.
How to do this, is a science that has been preserved in schools for thousands of years and the processes differ depending on the nature of our dominant concealed prejudice.
Science is also the uncovering of what was once not known but in this case what is learned concerns the laws of nature and how they work. So we have two kinds of science, one where the self learns what has always been a mystery about the universe, and the other, the science of why the self, the eye, can't see itself. This is done with mirrors, and of course, someone determined to learn. When the ego does science it can be objective or blind. We see that all the time in threads on evolution or global warming etc. But when the self observes the self and the self hates the self, there is always blindness. The blind will see no schools anywhere even when they are right under your nose. You have neither the need, conscious suffering, not the curiosity, you already know everything. Your tea cup is full.
So to recap, psychological knowledge reveals what we are and have always been, the genetic nature and human potential, and science reveals what was never know about the universe itself. What is really interesting, in my opinion, is how the relationship, if any, between the two. How did it happen that the experience of love is our highest emotion, at least according to some....
