Merely saying that someone believes that p does not imply anything about whether the .belief is held consciously and/ or held with certainty. In this paper I will give some analysis of such subjective differences of belief and try to express them in terms of the combinations of familiar epistemic operators such as the knowledge operator K and the belief operator B. Proper formulation of such differences will in turn clarify the interconnection between consciousness and certainty qua prop-erties of belief, and assure us that we do not have to take special care of these properties when we are concerned with formal theories of belief and knowledge.
