Stanislavski: Faith and a Sense of Truth

The 8th chapter of An Actor Prepares is about finding a sense of truth in your acting. I did not know if I was going to like this chapter, because my friend said that she did not like it after she read it. But, I found that I really liked this chapter for some reason. It talks about how when a person acts, they must use truth and a sense of belief. To quote the Director, "Truth on the stage is whatever we can believe in with sincerity, whether in ourselves or in our colleagues." This is completely true; I have been told by multiple directors that you need to believe what your fellow actors are saying and react to them. This creates a more truthful atmosphere for the audience (as well as for the actors on stage).
An actor must be able to observe himself thoroughly to be believable. In an exercise written about in the book, one female classmate of Kostya's did a monologue about finding a baby on her doorstep who later dies in her arms. She does this effectively, since she once dealt with a personal tragedy involving her own child, but she did not do it realistically. Another girl got up after her and did the same monologue. She was not in hysterics, as the first girl was, but was more realistic about it. Her version was much more effective for the class.
This is a chapter that I will have to look into more later on; I think it will be immensely helpful to my acting career.
