There is a kind of general disease of thinking which always looks for (and finds) a mental state // what would be called a mental state // from which all our acts spring as from a reservoir. Thus one says, “The fashion changes because the taste of people changes.” The taste is the mental reservoir. But if a tailor today designs a cut of dress different from that which he designed a year ago, can't what is called his change of taste have consisted, partly or wholly, in doing just this?
