Leadership and the Unmasking of Authenticity

The effects of the ultrasonic (US) pretreatment of synthesis gel for the preparation of mordenite zeolite were studied in comparison with the classical stirring method. Even though the US pretreatment was performed before the hydrothermal crystallization, it significantly affected the properties of the obtained mordenite crystals. The US-assisted procedure resulted in a material with improved textural characteristics, in particular, the micropore volume accessible for nitrogen molecules in the as-made form. On the other hand, mordenite prepared with the classical stirring method demonstrated comparable sorption properties only after a postsynthetic treatment. Moreover, in the case of US-pretreated mordenite, altered crystal shape and more homogeneous morphology were observed. 29Si magic-angle spinning nuclear magnetic resonance (MAS NMR) demonstrated that the US pretreatment introduced structural changes on the atomic level, resulting in fewer defects (reflected in the number of silanol groups) and less pore blockage (affected by Na+ cations) for the as-made sample.

This article presents a case that former President of the United States Donald Trump was a tyrant-like leader in the mold of the tyrant in Plato’s Republic. While he does not perfectly embody the tyrant as presented in the Republic, he captures its core feature. Like the tyrant, Trump is driven by unregulated desires that reflect what Plato describes as an extreme freedom that underlies and threatens democratic regimes. Extreme freedom is manifested in Trump’s disregard for social and legal norms, which mirrors the lawlessness of the tyrant. The people, in turn, interpret that posture as a mark of authenticity. Understanding Trump’s appeal in the United States helps alert friends of democracy to the possible rise of tyrant-like figures. In closing, and as a way of remedying the harm done by the tyrannical soul, the article recommends that society help temper tyrant-like passions in the people through a rededication to civic equality.
