The history of philosophical inquiry of time has been almost as long as the history of Western thought. Numerous concepts and ideas on the nature of time and time perception have been proposed over the centuries. Some of these ideas laid the groundwork for the psychological and neuroscientific studies of time processes. To this day, philosophical concepts inspire empirical research of time. In some cases, this interplay between philosophical ideas and neuroscientific studies of time processes occurs seamlessly. In other cases, however, attempts to directly apply philosophical concepts in the experimental research encounter impassable barriers. This commentary discusses two recent applications of philosophical frameworks of subjective time and time perception in the neuroscientific research.
