"Some mystery should be left in the revelation of character in a play, just as a great deal of mystery is always left in the revelation of character in life, even in one's own character to himself"

This quote by Tennessee Williams talks to the significance of leaving some secret in the revelation of character in a play. He recommends that just as in life, there is always a particular amount of mystery in the revelation of character, even in one's own character to oneself. This secret needs to be maintained in the characters of a play, as it adds a layer of realism and depth to the characters. Williams thinks that this secret needs to be delegated the audience to interpret, as it allows them to draw their own conclusions and form their own opinions about the characters. By leaving some secret in the discovery of character, the audience is able to engage with the characters on a deeper level and form a more significant connection with them.
