Artist tend to get solipsistic if not connected to thinkers or education. They need a context for their creative processes. Cistern gazing (getting lost in one’s own process) or over insularity are central shadows in most arts communites I’ve lived in. This is why i think historically, artists have hung out with thinkers. The two are meant to occupy the same cafe.
The teacher and the role of priest or prophet go together. In Jesus you see both aspects. Clear thinking is essential for artists to be near, so that they do not turn their process in on themselves or towards some form of hedonism. Celebrity is not a high enough goal. Artists want to express something meaningful–even the zeitgeist of their time.
Having worked with the arts for many years, i see several reasons for a need for clear exchange between arts and education. One is that educational institutions tend to have resources to held nurture and birth creative projects. Another is that education needs the life and innovation artist bring. There is also a spiritual dimension which artist should carry which is desperately lacking at most educational settings.
