One of the main advantages of Simulink is the ability to model a nonlinear system, which a transfer function is unable to do. Instead of using nonmonotonic logic, many philosophers, logicians, and computer scientists, such as John McCarthy (1977), Isaac Levi (1980), and Peter Gärdenfors (1988), have maintained that it is conceptually simpler to use first-order logic and adopt explicit metalevel methods for reasoning about the axioms of a theory.
