In order to be right about anything, the mind has the need to find someone or something that is wrong. In a sense, the mind is always looking for an enemy (the person who is “wrong”), since without an enemy, the mind is not quite sure of its own identity. When it has an enemy, it is able to be more confident about itself. Since the mind also continually seeks for certainty, which is a by-product of the desire to be right, the process of finding and defining enemies is an ongoing struggle for survival. Declaring enemies is, for the mind, not an unfortunate character flaw, but an essential and necessary task.
Unfortunately, being right is not what people really need, even though a great deal of their lives may be taken up in its pursuit. Defense of the ego is almost always a matter of trying to be right. Interestingly enough, Jesus never once suggeted to His disciples that they be right. What He did demand is that they be righteous. In listening to His words we find that we spend almost all our energy in the wrong direction, since we generally pursue being right with every ounce of our being, but leave being good to the weak and the naive.
