Art has the power to change us, inspire us, and make us see the world differently. Each work of art created by the individual artist reflects a time period, a context, a stage in his life. Thus in their works of art, the artist can see the development of his identity through time.
Art is also Philosophy because it reflects a perception that is desired and even loved. Wisdom and truth cannot be found through another but are found because of your love and desire for it and you have to have the eyes to see it.
