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.
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.
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.
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
The invention of the scientific method and science is, I’m sure we’ll all agree, the most powerful intellectual idea, the most powerful framework for thinking and investigating and understanding and challenging the world around us that there is, and that it rests on the premise that any idea is there to be attacked and if it withstands the attack then it lives to fight another day and if it doesn’t withstand the attack then down it goes. Religion doesn’t seem to work like that; it has certain ideas at the heart of it which we call sacred or holy or whatever. That’s an idea we’re so familiar with, whether we subscribe to it or not, that it’s kind of odd to think what it actually means, because really what it means is ‘Here is an idea or a notion that you’re not allowed to say anything bad about; you’re just not. Why not? – because you’re not!
