" There is a particularly unattractive and discouragingly common affliction called tunnel vision, which for all the misery it causes, ought to top the job list at the World Health Organization. Tunnel vision is a disease in which perception is restricted by ignorance and distorted by vested interest. Tunnel vision is caused by an optic fungus that multiplies when the brain is less energetic than the ego. It is complicated by exposure to politics. When a good idea is run through the filters and compressors of ordinary tunnel vision, it not only comes out reduced in scale and value but in its new dogmatic configuration produces effects the opposite of those for which it originally was intended.
