When you are engaged in argument with a perspective other than your own, there are sometimes moments in which you feel your thinking comes together just perfectly, and your perspective seems entirely self-evident and obvious. When this happens, it seems the only reason your opponent does not agree with you is due to obstinacy or stupidity. 

Pause, if you dare, at such moments, and contemplate that your opponent may have an equally sure sense of his or her own perspective--because he/she, like you, is seeing it from inside, with sympathy. In this frame of mind, the universe freely offers evidence to support one's own vantage point. Everything forms a kind of gestalt that confirms this particular conception of how reality holds together. 

Also, in argument, there are occasionally moments when it feels like you are being grossly misunderstood and unfairly attacked. Your position is being presented in an unfair light (maybe even perverted), and the arguments your opponent is refuting seem to be only bad parodies, straw men, of what you are actually trying to say. "How dare my opponent choose such an inadequate representation of what I'm trying to say ... and then to think that, in refuting that, he/she is successfully refuting me!" you protest. 

Again, at one of those moments, pause (only if you dare) and consider that your opponent him/herself may feel almost identically concerning the way you are handling his or her position. Whether or not you believe you are you are engaging primarily the least respectable representations of your opponent's position, that may be exactly what they perceive you to be doing--just as it seems (to you) that they are doing to you. 

It is sometimes clear only to someone outside the argument entirely, looking in, how much your assurance of being right is a mirror image of your opponent's assurance of being right, and how much your indignation at how unfairly your position is being portrayed and handled is a mirror image, also. 

"I hear what you're saying," I can hear you replying to me, "but in this case, in this argument, I really am right! My opponent really is wrong!" 

Exactly. 

This is not an attempt to say that all positions are equal, in terms of truth content, but a call to recognize that, much more than we realize, our perception of being right is conditioned by subjective factors that the other side is equally privileged to and plagued by. At the very least, it might encourage a welcomed increase of humility.
