Many different things come together to form a piece of art. The definition of art has changed throughout the years. Throughout time, people have questioned what makes art; is art just an imitation of nature or does it demonstrate internal emotions as well? Plato, in his work The Republic, supported the argument that art is copying the outer world. Aristotle, on the other hand, believed that art represented an object’s potential and that art should allow for an easier, more free approach to reality. I personally believe that art is a combination of the external world and one’s internal world or their perceptions of what occurs around them. My reasoning for this is because I believe that everybody’s perception of the world is relative and influenced by one’s experiences. Also I find it very interesting that art, while it can depict the truth, can also illustrate lies. By using various shapes and color combinations, one can create a illusion. These little pieces of art can be very significant. A single detail or color choice can highly influence one’s interpretation of a piece of art. For example, in the art piece Birth of the Virgin Mary, the painting has pictorial depth. This juxtaposes religion and science. These two things are very contrasting and yield to various interpretations. Art can mean something unique to whomever experiences it.
