How does phenomenological reduction change the focus from objects to consciousness?

In phenomenology, the phenomenological reduction—often associated with the technique of epochē—functions by shifting the philosopher's focus from the "natural attitude" of everyday life to the study of consciousness itself.12

This change in focus is achieved through the following process:

• Bracketing Existence: The phenomenologist "brackets" or suspends judgment regarding the actual existence or nonexistence of objects in the external world. This is not an act of doubt, but a methodological move to set aside the assumption that these objects are the primary theme of investigation.314
• Reversing the Direction of Sight: By putting the factual world in brackets, the reduction "reflects" or reverses the human direction of sight. Instead of being straightforwardly oriented toward external objects, the philosopher turns their attention toward the manner in which those objects appear to consciousness.14
• Focusing on Meaning: Once the existence of objects is suspended, the focus shifts to the phenomenon—that which is known in and by consciousness. This allows for an analysis of how objects are constituted as meaningful through various acts of consciousness, such as perception, imagination, and judgment.13

Ultimately, this reduction transforms the investigation into a "science of the essential structure of pure consciousness," prioritizing the study of how knowledge and meaning come about.12
