V. S. Styopin distinguished three types of rationality: classical, nonclassical and postnonclassical. The classical rationality is implemented in logic as a view of logic as a science of correct thinking. The nonclassical rationality is implemented in logic as a view of logic as a method of correct thinking. The postnonclassical rationality assumes the creation of meta-logic, i. e. interdisciplinary practice of researching logic as science and method of correct thinking.
