“I am a Southern man and a slaveholder. A kind and merciful one, I trust, and none the worse for being a slaveholder. I say, for one, I would rather meet any extremity upon earth than give up one inch of our equality, one inch of what belongs to us as members of this republic! What! Acknowledged inferiority! The surrender of life is nothing to sinking down into acknowledged inferiority!”

Context: There is scarcely any one who states purely arithmetical questions, scarcely any who understands them. Is this not because arithmetic has been treated up to this time geometrically rather than arithmetically? This certainly is indicated by many works ancient and modern. Diophantus himself also indicates this. But he has freed himself from geometry a little more than others have, in that he limits his analysis to rational numbers only; nevertheless the Zetcica of Vieta, in which the methods of Diophantus are extended to continuous magnitude and therefore to geometry, witness the insufficient separation of arithmetic from geometry. Now arithmetic has a special domain of its own, the theory of numbers. This was touched upon but only to a slight degree by Euclid in his Elements, and by those who followed him it has not been sufficiently extended, unless perchance it lies hid in those books of Diophantus which the ravages of time have destroyed. Arithmeticians have now to develop or restore it. To these, that I may lead the way, I propose this theorem to be proved or problem to be solved. If they succeed in discovering the proof or solution, they will acknowledge that questions of this kind are not inferior to the more celebrated ones from geometry either for depth or difficulty or method of proof: Given any number which is not a square, there also exists an infinite number of squares such that when multiplied into the given number and unity is added to the product, the result is a square.

"Angel Surrounded by Paysans" (1949)
Context: I am one of you and being one of you
Is being and knowing what I am and know.
Yet I am the necessary angel of earth,
Since, in my sight, you see the earth again,
Cleared of its stiff and stubborn, man-locked set
And, in my hearing, you hear its tragic drone
Rise liquidly in liquid lingerings,
Like watery words awash; like meanings said
By repetitions of half-meanings. Am I not,
Myself, only half a figure of a sort,
A figure half seen, or seen for a moment, a man
Of the mind, an apparition appareled in
Apparels of such lightest look that a turn
Of my shoulders and quickly, too quickly, I am gone?

Rex v. Cleg (1722), 1 Stra. 476.

Conclusion : The Moral of this Examination
A Perplexed Philosopher (1892)
Context: I care nothing for creeds. I am not concerned with any one's religious belief. But I would have men think for themselves. If we do not, we can only abandon one superstition to take up another, and it may be a worse one. It is as bad for a man to think that he can know nothing as to think he knows all. There are things which it is given to all possessing reason to know, if they will but use that reason. And some things it may be there are, that — as was said by one whom the learning of the time sneered at, and the high priests persecuted, and polite society, speaking through the voice of those who knew not what they did, crucified — are hidden from the wise and prudent and revealed unto babes.
