Some music theorists argue that music can arouse pity in the listener  But since pity can be felt only when there is someone or something to be pitied, and since nothing but the music is available to be the object of the listener' s pity, if anything is pitiable, then it is the music itself
But it makes no sense to say that a piece of music is pitiable; so music cannot arouse pity in the listener
Some people claim that the quality of one's life can be estimated by summing all the positive aspects of one's life and subtracting all the negative aspects. This implies that it is possible to place a numerical value on such things as health and emotional well-being; but trying to put a numerical value on such things is nonsense. Thus, the quality of a life cannot be measured in this way.
