“Who he was
That piled these stones, and with the mossy sod
First covered, and here taught this aged Tree
With its dark arms to form a circling bower,
I well remember.—He was one who owned
No common soul. In youth by science nursed.
And led by nature into a wild scene
Of lofty hopes, he to the world went forth
A favoured Being, knowing no desire
Which genius did not hallow; 'gainst the taint
Of dissolute tongues, and jealousy, and hate,
And scorn,—against all enemies prepared,
All but neglect. The world, for so it thought,
Owed him no service; wherefore he at once
With indignation turned himself away,
And with the food of pride sustained his soul
In solitude.”

“A thoughtful historian tells us that, between the Middle Ages and the nineteenth century, Italy produced three great men. As the first of these, he names Machiavelli, who he says, "taught the world to understand political despotism and to hate it"; as the second, he names Sarpi, who "taught the world after what manner the Holy Spirit guides the Councils of the Church"; and as the third, Galileo, who "taught the world what dogmatic theology is worth when it can be tested by science."”

“He, therefore, who desires peace, should prepare for war. He who aspires to victory, should spare no pains to form his soldiers. And he who hopes for success, should fight on principle, not chance. (Book 3, Foreword)”
Igitur qui desiderat pacem, praeparet bellum; qui uictoriam cupit, milites inbuat diligenter; qui secundos optat euentus, dimicet arte, non casu.

“All the time, he hoped they would understand that his arrogance masked only shyness—or did he hope that it was his shyness which masked arrogance? He did not know.
Who could presume to know? The one quality holds much of the other. Both refuse to come forward and share.”

“She shouted, “Arms and tongues, Spiral?” and waggled her arms and stuck out her tongue, and the old man crowed and did the same. “He’s for the first, against the second, as I recall,” she said to Ori. “Has he chanted for you? ‘Too much yammer, not enough hammer.’””

“A person who doubts himself is like a man who would enlist in the ranks of his enemies and bear arms against himself. He makes his failures certain by himself being the first person to be convinced of it.”

“For what did the creator prepare me,
Why did he so terribly contradict
The hopes of my youth?…”

“Yet he was jealous, though he did not show it, For jealousy dislikes the world to know it.”

“He is a fool who looks at the fruit of lofty trees, but does not measure their height.”
Stultus est qui fructus magnarum arborum spectat, altitudinem non metitur.

“He shall spurn fate, scorn death, and bear
His hopes 'bove wisdom, grace and fear:
And you all know, security
Is mortals' chiefest enemy.”
