This text presents a phenomenological analysis of sensory perception and the temporal manifestation of entities. The author argues that no entity reveals itself in its entirety at any single moment; instead, it unfolds through a temporal horizon. Consequently, perception cannot be reduced to the mere physiological functions of organs collecting isolated stimuli. A crucial role is played by the subject's ability to retain past experiences (retention) and anticipate future aspects of the entity (protention), which establishes meaningful continuity and a holistic image of the phenomenon. This mental image or percept is an active creation of the perceiving subject, yet it is not a mere subjective fantasy. Although perception is inherently subjective, it always contains an essential reference to a non-subjective reality. This reference is subject to ongoing verification and critique, allowing one to distinguish between a true phenomenon and sensory illusions or chaotic stimuli. The text emphasizes the intentionality and active nature of human consciousness in the process of constituting reality and interpreting the world.
