It is difficult to decide the importance of one set of senses over another, because consequentially, each of the senses enables the working of another or two of the senses. Seeing, hearing, smelling, feeling, and tasting are all somehow connected to each other; without one of the five, a particular system also becomes lacking in the sense department.
