[1] The preliminary step in the philosophical movement of phenomenology is to suspend judgment[2] (i.e., epoché) about the natural world and instead, to focus on analysis of experience.
Its earliest conception can be traced back to Immanuel Kant who argued that the only reality that one can know is the one each individual experiences in their mind (or Phenomena).
Attempting to resolve some of the key intellectual debates of his era, Kant argued that Noumena (fundamentally unknowable things-in-themselves) must be distinguished from Phenomena (the world as it appears to the mind).
[6] Bracketing (or epoché) is a preliminary act in the phenomenological analysis, conceived by Husserl as the suspension of the trust in the objectivity of the world.
It is supposed to make possible: the "unpacking" of phenomena, or, in other words, systematically peeling away their symbolic meanings like layers of an onion until only the thing itself as meant and experienced remains.
