Note 108 — Chapter V · EVOLUTION OF THE PRINCIPAL CONCEPTS.
Frances A. (Frances Alice) Welby translation
M. Janet has studied this subject, under the title “Une illusion d’optique interne” (Rev. Phil., 1877, III. pp. 497 et seq.) and explains the illusion by supposing that the apparent duration of a certain portion of time, in the life of each individual, is proportional to the total duration of his life.
