Tomorrow Never Knows

Tomorrow Never Knows, identified as a Beatles song, serves as a cultural marker for the Eastern-inflected understanding of psychedelic experience that became influential after Aldous Huxley’s 1954 book The Doors of Perception. The song is invoked as an example of how ideas about what an experience means can circulate beyond the people who first articulated them, helping shape later expectations of LSD.

A Cultural Marker

The song appears in a discussion of expectancy effects: psychedelic experiences are unusually susceptible to the expectations and interpretations brought to them. Aldous Huxley’s account helped cast the experience in mystical terms associated with Eastern thought. The passage uses Tomorrow Never Knows to evoke the wider cultural presence of that framing, which came to characterize the LSD experience from 1954 onward.

Expectation and Cultural Feedback

The song’s significance here is not presented as a report about its composition or as evidence that it directly caused particular experiences. Rather, it stands as one recognizable expression of a framework through which psychedelic experiences could be anticipated and interpreted. That framework could influence people who had read Huxley and, through its wider circulation, people who had not. The example thus supports the book’s broader point: psychedelic experience is partly constructed through ideas already available in the surrounding culture.
