How can we attain a true, diverse, multi-angled viewpoint of reality?

Question from the Internet:

“How can you use diverse viewpoints to support your own ideas?”

We are all born with an inherently egocentric, subjective perception of reality. Thus by birth, we are locked into an illusory reality we create for ourselves from the 100% egocentric, subjective impressions we receive from ‘outside”.

If we do not try to acquire multiple, diverse viewpoints from others to augment our own limited and distorted perception, we have no chance of attaining what reality actually is and we will keep stumbling from crisis to crisis, recurring vicious individual and collective cycles as we have done so far.

But if I want to use those multiple viewpoints only to support, prove my own ideas, my opinion, my understanding, that I am not going to achieve anything as I remain locked inside my own subjective, egoistic prison as before, but now I even proved to myself that I was right all along.

If we want a true, objective, unbiased perception of reality in order to understand, attain the world we live in, I have to give up all of my earlier ideas, preconceptions, “proof” and plans and I have to wash myself over the diverse, multi-angled viewpoints, ideas, plans and proof of others. Then from them, I can build the true, “holographic” image of reality I can exist in successfully.
