Many people think that good art is simply "what they like." Indeed while discussing the new "New York School" abstract impressionist stamps that are available a postal employee told me that she is "... just one of those people who knows what she likes. (in art)" In other words, she can't explain why she thinks one piece of art is better or more appealing than another. To me that is a cop-out. It is quite possible to study various works and learnt to articulate what is good and enjoyable or bad and unenjoyable about it.
