 What distinguishes acquaintance is, minimally, the following two closely related features. First, it is a nonjudgmental and nonconceptual form of awareness. Judgments, thoughts and concepts are essentially intentional or representational in nature, i.e., they are about or represent other things. Acquaintance with something does not consist in forming any judgment or thought about it, or in having any concept or representation of it. (In the second passage above Russell does characterize it as a special “cognitive” relation, but one must immediately wonder what this means given that he explicitly denies that it is judgmental in nature.) Second, it is a form of awareness constituting a real, genuine relation, a relation that cannot obtain without its relata (the things or items related). One cannot be acquainted with something that does not exist. Acquaintance is thus like the relation of kicking or throwing, for one cannot kick or throw without there being something that is kicked or thrown—something that is the object of the kicking or throwing. (Of course, these are not forms of awareness!) In contrast, judgments and concepts may represent or be about things that don’t exist. Philosophers sometimes refer to this second feature by saying that acquaintance is “infallible”. However, this term is most often used to refer to a property of beliefs: roughly, a belief is infallible if it is immune to error or is guaranteed to be true. Given the first feature above, being acquainted with something is not to be understood in terms of having a belief or judgment about it, not even an infallible one.
