All the senses are vital to relationship.
Yet the eye is arguably the most easily deceived; slight of hand, smoke and mirrors create illusions that feel true. Vision can only take a person so far.
Its interesting to me that counselors and relational theorists more concerned about hearing/listening in communication. Yes, vision plays a vital role in hearing, think of the non-verbal communication of body language. In this sense vision is a type of hearing.
Why is it that a person cannot understand a culture without understanding its language?
Listening requires the submission of my will to hear the other. Vision is about self determining and interpreting what self sees.
The whole person is needed in relational leadership, and vision (I would argue) is the weakest of all the senses interpersonally.
