Friedrich Nietzsche - IEI (INFP) "Yesenin".
German philosopher, one of the most influential of all modern thinkers.

🪩His mirror-type Beta quadra companion Arthur Schopenhauer, who was EIE, strongly influenced his philosophical thought.

🔎More than 100 years ago, Carl Gustav Jung defined Nietzsche as an introverted intuitive type; we fully confirm these conclusions taking into account the methods of modern socionics. At the same time, it is important to mention that Nietzsche's introverted intuition is combined with an extroverted ethical function.
