"A lot of people insisted on a wall between modern dance and ballet. I'm beginning to think that walls are very unhealthy things"

Twyla Tharp's quote speaks with the idea of department and separation between two art kinds. She is suggesting that the concept of a wall between contemporary dance and ballet is an unhealthy one. This might be translated as a metaphor for the idea of separation in between different groups of people, or between various ideas. By recommending that walls are unhealthy, Tharp is suggesting that it is much better to have open communication and understanding between different groups, rather than to develop a barrier in between them. This might be seen as a call for unity and partnership, rather than division and separation. Tharp's quote is a tip that walls can be destructive and that it is essential to strive for understanding and acceptance in between various groups.
