The article presents Erwin W. Straus' unpublished manuscript "Temporal Horizons" from 1952. In the paper, in addition to an extensive philosophical discussion with St. Augustine, Henri Bergson and Sigmund Freud, Straus elaborates on his idea of a unified view of temporal experience, comprising both the personal and the impersonal dimensions of time. The manuscript also contains an interview with a psychotic patient, which is supposed to exemplify Straus' core idea on the psychotic temporal experience, according to which the break of the invisible bond between immanent or personal, and clock or impersonal time leads to a loss of a sense of reality.
