Thinking of the ancient Greek philosophers — is the key to creation of modern philosophy as a strict cumulative science

A new method of adult and children mental development is investigated – the trilogy of mind, which basic operation is the logic operation of comparison. This method was created considering Aristotle's understanding of philosophy as “the science about the first reasons and origins” of cognition, the beginning of presocratic cognition of the surrounding world. This new method is an effective mean of mental thinking development that is oriented at the understanding of natural and social processes with the help of general scientific comparative notions – kinds of opposition, worked out in ancient times.
