Step-by-step explanation:
According to Immanuel Kant, the self is not only personality, but also a seat of knowledge option (a). Kant believed that the mind makes an active contribution to our experience of objects, and that our knowledge is shaped by our senses and conceptual capacity. He argued that we can have knowledge of objects because of our consciousness, but our knowledge is limited to the categories of understanding. In terms of moral action, Kant believed that acting rationally is necessary to affirm our worth and dignity.
