 An objection to the New Knowledge/Old Fact View can be made as follows. In standard cases, if a subject does not know a given fact in one way that it does know in some other way, this can be explained by two modes of presentation: the subject knows the fact under one mode of presentation and does not know it under some other mode of presentation. So, for example, a person may know the fact that Venus is a planet under the mode of presentation associated with “the morning star is a planet” and fail to know the very same fact under the mode of presentation associated with “the evening star is a planet.” In this particular case, as in many others, the difference in the mode of presentation involves two different properties that are used to fix the referent. In one mode of presentation Venus is given as the heavenly body visible late in the morning (or some similar property), whereas in the other mode of presentation the object is given as the heavenly body visible early in the evening.
