The goal of phenomenological reduction is to bracket or set aside our assumptions and beliefs about the world in order to access pure consciousness, the unmediated experience of things as they are given to us.

The epoché allows us to bracket or set aside our assumptions and beliefs about the world, thereby enabling us to focus on the relationship between consciousness and the world as it is given to us in experience.

The natural attitude is the way we normally experience the world, based on our everyday assumptions and beliefs. The phenomenological attitude, on the other hand, involves bracketing or setting aside these assumptions and beliefs in order to focus on the pure experience of things as they are given to us.

The three main types of epoché are descriptive epoché, transcendental epoché, and existential epoché. Descriptive epoché involves bracketing or setting aside our assumptions about the world in order to focus on the pure experience of things as they are given to us. Transcendental epoché involves bracketing or setting aside the existence of the world in order to focus on the structures of consciousness. Existential epoché involves bracketing or setting aside our own existence in order to focus on the being of things.

By bracketing or setting aside our assumptions and beliefs about the world, the epoché allows us to overcome skepticism and achieve certainty and knowledge about the structures of consciousness and the relationship between consciousness and the world.
