Note Footnote 7: — INTRODUCTION.
Reading edition
Some logicians in expressing the Law of Identity have their eye specially upon the objects signified by general names or abstract names, man, education.7 "A concept is identical with the sum of its characters," or, "Classes are identical with the sum of the individuals composing them". The assumptions thus expressed in technical language which will hereafter be explained are undoubtedly assumptions that Logic makes: but since they are statements of the internal constitution of some of the identities that words represent, to call them the Law of Identity is to depart confusingly from traditional usage.8
