“...as man under pressure tends to give in to physical and intellectual weakness, only great strength of will can lead to the objective.”

“Where execution is dominant, as it is in the individual events of a war whether great or small, then intellectual factors are reduced to a minimum.”

“Great things alone can make a great mind, and petty things will make a petty mind unless a man rejects them as completely alien.”

“All war presupposes human weakness and seeks to exploit it.”

“...an intellectual instinct which extracts the essence from the phenomena of life, as a bee sucks honey from a flower. In addition to study and reflections, life itself serves as a source.”

“If the mind is to emerge unscathed from this relentless struggle with the unforeseen, two qualities are indispensable: first, an intellect that, even in the darkest hour, retains some glimmerings of the inner light which leads to truth; and second, the courage to follow this faint light wherever it may lead.”

“If the leader is filled with high ambition and if he pursues his aims with audacity and strength of will, he will reach them in spite of all obstacles.”
