Kay Larson, writing about the reaction to Marcel Duchamp’s Fountain in Where the Heart Beats: John Cage, Zen Buddhism, and the Inner Life of Artists:
The eruptions of violated sensibility were coming from human beings, whose unexamined expectations, habitual beliefs, moral rigidity, squeamishness about the body, conditioned responses, and exalted sense of propriety were causing howls of anguish. This raging cyclone of emotion is a succinct definition of dukkah—the Sanskrit word that sums up the suffering of cyclical existence, brought on by our ego fixations. Buddhists call this realm “samsara,” the troubled world created by our rigid ego habits: our clinging to the categories we invent, investing them with reality, punishing those who don’t agree.
See also the synopsis of “The Inadequacy of Mass Education & the Case for Autodidacticism" by Jordan Bates:
(…) autodidacticism is an attitude one brings to learning, an attitude which is essential to gaining substantive insight both within and beyond the confines of traditional educational institutions. This attitude consists of a willingness to question all of one’s assumptions and preconceived ideas, a strong desire to learn and to apply what is learned, and a fiery love for knowledge in and of itself.
Sounds like one way to combat the rigid ego habits. See also cultural dark matter.
