Really, our continuing to be enlightened confirms that we are on the right path.
No, it confirms that you are always wrong. Replacing the phrase "to be enlightened" with "to change our minds" (which is 100% fair and honest) is much more accurate. Would you consider someone who could never make up his/her mind to be "on the right path"? Would you take seriously a person that constantly changed their mind and insisted that each new idea was the truth, indisputable fact? Enlightenment implies a constant, forward march toward truth, not flip-flopping, back-stepping, and circling.
