Conceptions of certainty

There have been many different conceptions of certainty. Each of them captures some central part of our intuitive understanding of certainty, but, as we shall see, none of them is free from problems.

"The music of French-American composer Dane Rudhyar (1895–1985) has remained virtually untouched by analysis for almost a century. Even though Rudhyar’s importance in the development of American music has been increasingly acknowledged by historians in the past two decades, his compositions have still received only the most superficial attention. Some of this neglect may result from Rudhyar's musical language itself, which—because of its highly idiosyncratic, personal nature—does not readily invite analysis."
