In a world driven by emotions and ignorance, what is the best tool a wise man should weild? Pure logic and true knowledge.

A good leader especially should be driven by the motive of bringing up his men with his power of wisdom and compassion, for the ultimate development and welfare of his beloved brotherhood.

Just be a man unmoved by emotional stimuli or material urges, never being ashamed to admit your ignorance and having the right aim of quenching your never-ending thirst of knowledge. Exhibiting emotional behavior and making irrational decisions driven by your insecurities is for the children and females, not for the strong and brave ones.
