This paper considers the cognitive penetrability of our experiences of the durations of everyday events. I defend an account of subjective duration based in contemporary psychological and neurobiological research. I show its philosophical adequacy by demonstrating its utility in explain-ing the phenomenology of duration experiences. I then consider whether cognitive penetrability is a problem for these experiences. I argue that, to the contrary, the problem presupposes a relationship between perception and belief that duration perceptions and beliefs do not exhibit. In-stead, (...) the assignment of epistemic features to particular processing stages appears to answer to pragmatic needs, not psychological facts. (shrink)
