The point of the elephant and the blind man is that we all are those blind men. The elephant exists, but us being blind cannot truly understand what it is, touching only parts of it and extrapolating our ideas of what it is. I would not say the motives are rooted in self-gratification or self-reliance, or some ego thing. It's simply a matter of the mind trying to grasp with the mind, something which is beyond it's ability to fathom giving the resources available to it. What is ego, is when we say our understanding is "The Truth!", because we believe it to be so. That describes all of these "The Bible says", arguments. Ego. Being "right", while being blind only experiencing partial truths, relative truths to our points of view, like the blind men and the elephant.
