 Thus, Leibniz may be seen as providing a fully naturalized philosophy of mind in which he advocates for a threshold theory of consciousness. This is a same-order theory of consciousness—for Leibniz, a conscious perception is a distinct perception. That is, at some level of distinctness, the perception stands out sufficiently to be noticed. All perceiving substances have perceptions that have some degree of distinctness, but not all perceiving substances have distinct perceptions. Rather, it requires some threshold degree of distinctness (relative to context) for a perception to be distinct. (For a full account of this position, see ch. 7 of Jorgensen 2019.)
