+AMONG the many valuable contributions of William Dwight Whitney to
+linguistic science is one especially important and fundamental
+principle. It may be stated in these words. In explaining the
+prehistoric phenomena of language we must assume no other factors than
+those which we are able to observe and estimate in the historical
+period of language development. The factors that produced changes in
+human speech five thousand or ten thousand years ago cannot have been
+essentially different from those which are now operating to transform
+living languages. On the basis of this principle we look to-day at a
+much-discussed problem of Indo-European philology with views very
+different from the views held by the founders of Comparative Philology
+and their immediate successors. I refer to the problem, how the
+Indo-European people came to assign gender to nouns, to distinguish
+between masculine, feminine, and neuter. This question is of interest
+to others besides philologists. What man of culture who has learned
+languages such as the Greek, Latin, or French has not at times
+wondered that objects which have no possible connection with the
+natural gender of animals appear constantly in the language as male or
+female? In German, for example, it is der fuss, but die hand; der
+geist, but die seele; in Latin, hīc hortus, hīc animus, hīc amor, but
+haec planta, haec anima, haec felicitas; in Greek, ὁ πλοῦτος, ὁ οἶκος,
+but ἡ πενία, ἡ οἰκία.
+
+This gender distinction pervades all the older Indo-European
+languages, and must therefore be regarded as having its origin in the
+time of the pro-ethnic Indo-European community. Not only is the
+subject itself full of interest, but also the treatment it has
+received from the philological research of our century. The various
+efforts made to solve the problem may very aptly illustrate an
+essential difference which exists between the theories of language
+development held in the beginning and middle of this century and those
+which prevail to-day, — a difference of method existing not in
+comparative linguistics alone, but also in other fields of
+philological and historical research that border on it.
