Successful actors and actresses have to get themselves into their roles before acting. Therefore, you need to really care about what you are saying.

However much you know giraffes, to see one in the wild for the first time feels prehistoric.

Words can enhance experience, but they can also take so much away. We see an insect and at once we abstract certain characteristics and classify it - a fly. And in that very cognitive exercise, part of the wonder is gone. Once we have labeled the things around us we do not bother to look at them so carefully. Words are part of our rational selves, and to abandon them for a while is to give freer reign to our intuitive selves.

The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man - whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them.
