A man, to succeed, must possess the necessary equanimity of temperament to conceive an idea, the capacity to form it into some tangible shape, the ingenuity to put it into practical operation, the ability to favorably impress others with its merits, and the power of will that is absolutely necessary to force it to success.
Nothing is as difficult as to achieve results in this world if one is filled full of great tolerance and the milk of human kindness. The person who achieves must generally be a one-ideaed individual, concentrated entirely on that one idea, and ruthless in his aspect toward other men and other ideas.
If you have a large number of unrelated ideas, you have to get quite a distance away from them to get a view of all of them and this is the role of abstraction. If you look at each too closely you see too many details. If you get far away things may appear simpler because you can only see the large, broad outlines; you do not get lost in petty details.
– John Kemeny (1926-1992) Mathematics: People, Problems, Results
Experience is, for me, the highest authority. The touchstone of validity is my own experience. No other person’s ideas, and none of my own ideas, are as authoritative as my experience. It is to experience that I must return again and again, to discover a closer approximation to truth as it is in the process of becoming in me. Neither the Bible nor the prophets — neither Freud nor research — neither the revelations of God nor man — can take precedence over my own direct experience. My experience is not authoritative because it is infallible. It is the basis of authority because it can always be checked in new primary ways. In this way its frequent error or fallibility is always open to correction.
What kind of idea are you? Are you the kind that compromises, does deals, accommodates itself to society, aims to find a niche, to survive; or are you the cussed, bloody-minded, ramrod-backed type of damn-fool notion that would rather break than sway with the breeze? The kind that will almost certainly, ninety-nine times out of hundred, be smashed to bits; but, the hundredth time, will change the world.
