The paper aims to analyze the construction of the fichtean concept of phenomenology as a reaction to the phenomenology presented by Reinhold in the Beytraege of 1801-1803 (§ 3), from an investigation of the occurrences of this term in the second exposition of the doctrine of science of 1804 (§ 2 and § 4) and in the Sittenlehre of 1812 (§ 5). Finally, the paper will outline some implications of a more specific contextualization of the fichtean concept of phenomenology in the definition of possible elements to investigate the relationship between fichtean and husserlian phenomenology.
