THE significance of our reconstructed forms, precisely what is intended by them, is an old question which some of us discussed briefly at the St. Louis Congress of Arts and Sciences of 1904 (cf. the publication, vol. III, pp. 35, 57), and which has been elaborated in the long article of E. Hermann, KZ 41. 1ff. There is not only a difference in the views expressed by various scholars, but often in the case of the same one an apparent discrepancy between the interpretation of reconstruction that is explicitly professed and that which must be inferred from his practice. For example Meillet, Introd. 24ff., insists on the unreality and the purely formulaic character of the reconstructions, saying that these are nothing but convenient formulae for given correspondences (similarly Oertel, Lectures 128, and others). Yet throughout the work he is constantly, like any other scholar in the field, asserting or discussing the sound, form, or type that must be assumed for the parent speech to account for given correspondences, and whether this and that type is inherited from the parent speech or an innovation. Again, not believing in the existence of three guttural series in the parent speech, he does not recognize the ‘plain velars’ of other scholars, whereas from his professed principle one would expect him to have the least compunction in admitting them as convenient formulae for a well-known set of correspondences. The fact is, of course, that to him, and to all, the reconstructions, while mainly useful as formulae, are still something more than mere formulae of correspondences, they imply a certain interpretation of these correspondences, a conviction or a provisional theory regarding their approximate common starting point.
