There are a lot of problems with that chart. It doesn't represent and confuses the essentials and the structure as Ayn Rand presented them. A later revision of the chart made some important corrections, but not enough.

The thing I appreciate about this chart is that it puts values/ethics as the primary/center. It is BECAUSE we want Human Thriving for ourselves that metaphysics and epistemology matter - we need them to adequately understand reality such that we can work with/in it to achieve our values.

Similarly, politics is the extension of morality to groups/larger contexts.

Typically, aesthetics is tagged on the end - which is why it isn't part of the standing on one foot list. However, I argue that Aesthetics is about creativity/intuition/realization - far more than art and artistic expression. It is about the telos towards which we develop - the highest realization of which we are possible as human beings. And this telos is something we construct/create/imagine/envision - deeper and wider and farther and more beautiful - forever. It is limited only by our own depth as human beings, and the deeper we are, the higher we envision - which makes us deeper - but only forever.

In this sense, Aesthetics is actually PRIOR to ethics. It is the story in which ethics works out the plot of good/bad, success/failure. It is the sense of life that sets the pinnacle of values from which we can rationally establish the hierarchy of marginal priorities. Aesthetics is the beginning and the end of ethics. Ethics is, in this sense, the tool of aesthetics in the same way that epistemology is the tool of ethics.
