Rigor Quotes - page 2
The function just found cannot, it is true, express rigorously the probabilities of the errors: for since the possible errors are in all cases confined within certain limits, the probability of errors exceeding those limits ought always to be zero, while our formula always gives some value. However, this defect, which every analytical function must, from its nature, labor under, is of no importance in practice, because the value of our function decreases so rapidly... that it can safely be considered as vanishing. Besides, the nature of the subject never admits of assigning with absolute rigor the limits of error.
Carl Friedrich Gauss
Ascetic rigor? This doesn't mean something like ‘renounce' or even a ‘lack' of something. No, it means, in philosophical manner (and especially in the historic Greek sense of ‘Askesis'), a special kind of internal yearning, a special power wherein, despite all depressions, defeats, and failures you develop a new power to ‘keep' to something, to create something. It's something like an obsession. Bach, Mozart, Schubert, they all (and their oeuvre) are filled from this phenomenon, and it's this spirit which keeps this music so vivid and alive – and fashioned for all times and generations.
