Intuitively, the concept of unity in art refers to the representation of compositional elements precisely arranged within a work to achieve a composite whole whereby the sum of said compositional elements adhere to some generally recognized standard of balance, rhythm, and harmony.
More simply put, good art looks good.
This very simple concept has a long and glorious history that reaches back thousands of years. Rather than chronicle the entire history of humans thinking about art, I’ll simply share interesting term I learned called organic unity. As outlined by Catherine Lord in her 1964 paper “Organic Unity Reconsidered”, this term puts forward the following three premises: “1) Subtraction or addition would diminish the value of the work of art as a whole. 2) Subtraction or addition changes the character of all the contained parts of the work of art, and 3) Every part of the work of art is not equally important when importance means prominence or impact.”
She goes on to argue that the third premise supersedes the first two, and then throws out the whole sordid affair because How Dare You shackle art to one single model of “unity” in the first place![also 2]
Which is great, because now we’re right back where we started. Isn’t philosophy fun?
De gustibus non est disputandum.
