The name "phenomenology" appears to have been used for the first time by Johann Heinrich Lambert in his Neues Organon (1764). The word also occurs in Kant (Metaphysische Anfangsgrunde der Naturwissen-schaft, 1786), Hegel (Phänomenologie des Geistes, 1807), Renouvier (Fragments de la philosophic de Sir W. Hamilton, 1840), Hamilton (Lectures on Logic, 1860), Amiel (Journal intime, 1869), E. von Hartmann (Phänomenologie des sittlichen Bewuβtseins, 1879), and in other works. The meaning attached to it has differed very greatly from one writer to another, but none of these early writers used it to denote a precisely circumscribed method of thought.
