Our intention in this Disme is to worke all by whole numbers: for seing that in any affayres, men reckon not of the thousandth part of a mite, grayne, &c. as the like is also used of the principall Geometricians, and Astronomers, in computacions of great consequence, as Ptolome & Johannes Monta-regio have not described their Tables of Arches, Chords, or Sines, in extreme perfection (as possibly they might have done by Multinomiall numbers,) because that imperfection (considering the scope and end of those Tables) is more convenient then such perfection.

The very first thing the President did was to show me the new Presidential Seal, which he had just redesigned. He explained, 'The seal has to go everywhere the President goes. It must be displayed upon the lectern when he speaks. The eagle used to face the arrows but I have re-designed it so that it now faces the olive branches ... what do you think?' I said, 'Mr. President, with the greatest respect, I would prefer the American eagle's neck to be on a swivel so that it could face the olive branches or the arrows, as the occasion might demand.

If children had teachers for judgment and eloquence as they have for languages, if their memory was exercised less than their energy or their natural genius, if instead of deadening their vivacity of mind we tried to elevate the free scope and impulses of their souls, what might not result from a fine disposition? As it is, we forget that courage, or love of truth and glory are the virtues that matter most in youth; and our one endeavor is to subdue our children's spirits, in order to teach them that dependence and suppleness are the first laws of success in life.
Luc de Clapiers, Marquis de Vauvenargues
Our world is not an optimal place, fine tuned by omnipotent forces of selection. It is a quirky mass of imperfections, working well enough (often admirably); a jury-rigged set of adaptations built of curious parts made available by past histories in different contexts. [...] A world optimally adapted to current environments is a world without history, and a world without history might have been created as we find it. History matters; it confounds perfection and proves that current life transformed its own past.

I was appalled to find that the mathematical notation on which I had been raised failed to fill the needs of the courses I was assigned, and I began work on extensions to notation that might serve. In particular, I adopted the matrix algebra used in my thesis work, the systematic use of matrices and higher-dimensional arrays (almost) learned in a course in Tensor Analysis rashly taken in my third year at Queen's, and (eventually) the notion of Operators in the sense introduced by Heaviside in his treatment of Maxwell's equations.

Of the various executive abilities, no one excited more anxious concern than that of placing the interests of our fellow-citizens in the hands of honest men, with understanding sufficient for their stations. No duty is at the same time more difficult to fulfil. The knowledge of character possessed by a single individual is of necessity limited. To seek out the best through the whole Union, we must resort to the information which from the best of men, acting disinterestedly and with the purest motives, is sometimes incorrect.
