"Now," he said, "may I enter as evidence the suit that the slain man was wearing? It is--or was--identical to that which my client is wearing now. At the present time," he said with a smile, "the client's suit is a little more worn, though in better condition due to the holes in this one. Now, for my first witness I call Dr. Lewis." * * * * * "Dr. Lewis, have you ever considered the being of a duplicate?" "Not until recently," smiled the doctor. "You are a competent psychiatrist. Can you tell us the responsibility-quotient of a man kept in a state of suspended animation until he was thirty-three years old?" "He would have little or no sense of responsibility at all." "Would you say then that a duplicate of any human being was responsible for the acts of the original?" "I would hate to ponder the question," replied the psychiatrist. "It would depend entirely upon the degree of duplication. Yet it seems to run against the grain to make a duplicate responsible for the acts of the original when up to this time the duplicate had no true identity." "You assume the duplicate would have an identity?" "If the duplicate is capable of original thought, he has." "Yet, Dr. Lewis, what comprises identity?" "The ego is a rather deep subject," replied the doctor thoughtfully. "The question 'What is this that am I?' is one pondered for many thousands of years. It is still without answer--though it is generally accepted that a man is what he is because of his lifetime of experiences." "Will you expand upon that, doctor?" The doctor nodded. "A new-born babe has little true identity or individuality. That is because his only experience is almost congruent with all other new-born babes. As he lives, his experiences will differ because of environment and heredity from others--in the case of twins this is true despite the idea that the environment and heredity is identical. It is not. The environment of Twin A includes the life of Twin B, and vice versa. Therefore each twin must evolve a different identity. As a man grows and enjoys experience, each factor changes his personality in some way major or minor, and he emerges a true identity, which, however, is different in some minor way from day to day as his experiences accumulate." "Then at the instant of duplication, the two persons have approximately the same identity?" "Yes save for the single fact that one has just been in the process of formation whilst the other was in the process of being recorded. I assume that the two processes are not identical."
