This philosophical reflection from 1970 critically examines the concept of normality, challenging its common identification with statistical averages or prevailing standards. The author observes that what is deemed "usual" is inherently fluid; for example, an epidemic can temporarily make illness the societal norm. Such variability calls into question the validity and binding nature of norms derived solely from frequency. The text posits that neither medicine nor individual conduct should target a standardized human type. Instead, normality is presented as a form of life integrity that must be actively and repeatedly achieved. A crucial element of this definition is its temporal nature; normality is not a static state associated with a particular age, such as youth, but rather the capacity to integrate all stages of life, including youth and old age, into a unified whole. Ultimately, normality is defined by the ability to synthesize vast temporal and spatial dimensions into a coherent existence, making it a dynamic achievement of existential wholeness rather than a mere adherence to external averages.
