ABSTRACT
'Identity' can only be predicated of two different structures if the two structures possess at least the same degree of manifoldness. The reader can work out for himself in detail to what extent Kant's so-called theory of antinomies collapses on being tested with the canon of the correspondence of the degrees of manifoldness, though this theory can be refuted on other grounds also. Two different objects of mediate construction can only be characterized as the same if psychologists possess an equal degree of the manifoldness, so that every part of the one object exactly corresponds to a part of the other. A particular case of non-correspondence between two degrees of manifoldness exists when the one object possesses given parts, perhaps of a relative kind without the latter having, as a possible equivalent, parts which are not possessed by the former.
