Recently, the debate on the theory of conceivability recently examined the relationship between conceivability and the ability per se and instead concerned the conditions for the realization of the physicalist program. However, before entering this debate, it is necessary to ask whether conceivability offers same elementary justification modal beliefs. I support two methods to design - imagine that p and tell a story about p - are likely to provide this justification, but only within the limits of certain conditions. In support of my argument, I consider the position of Paul Tidman, which I use as a foil.
