"Now life is the only art that we are required to practice without preparation, and without being allowed the preliminary trials, the failures and botches, that are essential for the training of a mere beginner. In life, we must begin to give a public performance before we have acquired even a novice's skill; and often our moments of seeming mastery are upset by new demands, for which we have acquired no preparatory facility. Life is a score that we play at sight, not merely before we have divined the intentions of the composer, but even before we have mastered our instruments; even worse, a large part of the score has been only roughly indicated, and we must improvise the music for our particular instrument, over long passages. On these terms, the whole operation seems one of endless difficulty and frustration; and indeed, were it not for the fact that some of the passages have been played so often by our predecessors that, when we come to them, we seem to recallsome of the score and can anticipate the natural sequence of the notes, we might often give up in sheer despair. The wonder is not that so much cacophony appears in our actual individual lives, but that there is any appearance of harmony and progression."
Lewis Mumford, Historian of Technology & Science, (1895-1990)
