This text explores the nature of the phenomenological approach to reality, emphasizing the distinction between how things truly manifest and how they are perceived. The author asserts that reality does not reveal itself in its entirety but only appears to us, with the subject playing an essential role in this process of manifestation. A critical focus is placed on the strict differentiation between a momentary appearance and a phenomenon. Although we commonly refer to appearances as noticeable events, strictly speaking, a true appearance lasts only a fleeting instant, often too brief for human detection. The text argues that human perception requires not only a certain intensity of stimulus but also a necessary duration to register the experience. Consequently, the phenomenological method is justified in its study of how things manifest, acknowledging that our perception relies on the temporal extension of these otherwise momentary flashes of reality.
