However, within the Organon, Aristotle is not content with merely providing the axiomatic theory of syllogism. The range of means offered by Aristotle for the victorious conduct of arguments in discussions is much broader than that. Thus it is evident, that in subsequent centuries, based on the Organon, logic contains much more than the theory of formal analysis of deduction or the theory of some abstract objects. At the same time the philosophical spirit of logic was almost entirely lost. But today, when we speak of contemporary logic, we cannot mean exclusively that part of modern logic which is called classical symbolic logic.
Contemporary logic provides more than formal study of deducibility.
Making use of the results of formal studies and not divorced from them, it examines problems with philosophical content, some of them already occurring in Aristotle's work and only later removed from logic by the members of the early neopositivistic movement during the initial stage of modern logic. To resort again to an analogy, let me mention the fact that most of the ancient Greek statues were originally colored. In the course of centuries they become soiled. When they were found and people tried to clean them, they lost their coloring. That was one of the reasons why uncolored sculpture became fashionable.
