Solitude can be viewed as a form of emancipation from societal exceptions, family obligations, and personal transgressions. The quixotic notion of a disciple walking into a cave/ up a tall mountain/ mythical Shangri-La where the ascetic lives in austere isolation, chanting, meditating, praying with her mind swellings in the juices of their innermost thoughts and beliefs, until the crescendo of epiphany, enlightenment or nirvanic state appears.
Solitude is seen by some as virtuous self-sacrificing, introverts are now celebrated, offline is the new luxury, in reality, solitude is a personal copout, much like the revival of isolationist policies of nation-states. Isolationism from Sakoku policies of the Japanese Tokugawa shogunate or "America First" themes of the present Trump administration are defensive cowering from needed fundamental reforms in a nation.
