Meaninglessness, Yalom (Existential Psychotherapy. Thomson Brooks/Cole Publishing Co, 2005, p. 447) notes, seems to afflict patients with increasing frequency in contemporary life. Yalom partly puts this down to cultural changes that have replaced the usual sites from which people might draw meaning (like religion, work, or routine contact with the natural world) with a secular, rationalistic, and industrialised context that offers little in the way of clear purpose or explanation for their existence. Recent scholarship on topics like everyday spirituality (MacKian, Everyday Spirituality: Social and Spatial Worlds of Enchantment. Springer, 2012), wonder (Derné et al., Sociological Inquiry, 92(4), 1306–1328, 2022), and enchantment (Bennett, The Enchantment of Modern Life. Princeton University Press, 2016) have indicated ways in which people respond to a world where shared patterns for meaning-making are less secure (the so-called disenchantment thesis). This chapter uses empirical data collected from a recent Mass Observation Project Directive on ‘everyday mystery’. It examines how not-knowing might be considered one everyday response to the ‘givens’ in contemporary social life, exploring Yalom’s philosophical approach in the context of the practical accomplishment of mystery within day-to-day life.
