A Tuesday Thought

It's sometimes a bit difficult to understand what the great thinkers are getting at in their pronouncements.  That might be the case in this quote from the renowned philosopher Julius Henry Marx (1890-1977):

"Well, Art is Art, isn't it? Still, on the other hand, water is water. And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now you tell me what you know."
