"Having an experience" vs "conceptual understanding"

What is the difference discussed in this article between "having an experience" and "conceptual understanding"?

War and injustice are major concepts in art. It is important to understand their role as subject matter. Francisco De Goya’s piece entitled “Execution of the defenders of Madrid”, also known as “The shootings of May 3 1808” and Picasso’s painting “Guernica” express these concepts with two completely different voices, or styles. Despite the drastic differences in style, the concepts are revealed quite successfully in both pieces on the faces and in the positioning of the characters in these pieces. So, to simply view these pieces, while it may be valuable, does not contribute to an educational experience. To have an educational experience the viewer would, number one, need to feel a level of anticipation about the events these paintings are portraying. An anticipation that there was more to be discovered surrounding these events. Second, this anticipation would need to lead to the formulation of ideas regarding what the paintings are suggesting about war and it’s effects on humankind. Third, these ideas would invoke action on the part of the viewer. An action that would lead to a more cohesive understanding of how the events or feelings depicted have been explained in the piece. Only in these actions do ideas find meaning and value. Ultimately this understanding would require the accompaniment of an emotional response to this anticipation, rather then to the general like or dislike of the piece, a response that would include feelings from participating in the experience of these ideas. This unity of Anticipation, Ideas, Action and Emotion is what Dewey would consider an authentic educational experience. These four principals are what separate a conceptual understanding of war and injustice as subject matter in art to an educational experience. They transform an indifferent opinion of a depicted event to a sublime understanding of the social commentary incorporated in art.
