  Extrapolating from this, we may say that my gray idea of the cherry, formed in dim light, is not in itself wrong and forms a part of the bundle-object just as much as your red idea, formed in daylight. However, if I judge that the cherry would look gray in bright light, I’m in error. Furthermore, following Berkeley’s directive to speak with the vulgar, I ought not to say (in ordinary circumstances) that “the cherry is gray,” since that will be taken to imply that the cherry would look gray to humans in daylight.
