A special variable corresponds to the subject's intention. This development allows us to include within the model freedom of will and freedom of choice, and also to generalize classical 2×2 game theory to the case where outcomes, in addition to having utility measures, are either `positive' or `negative.' In its concluding chapters the book constructs a dynamic model of the intentional subject faced with a choice between two alternatives, neither of which is morally acceptable for the subject. It is shown that in this case the probabilities of choice of the alternatives may change chaotically. From this it follows that one cannot predict which alternative will be chosen or even the probabilities with which they will be chosen. Audience: The book is addressed to a broad readership having elementary knowledge of mathematical logic and the theory of probability.
