654 IX. ON EMPIRICAL AND VERBAL STRUCTURES
the old is impossible. The old is due to objectification of the structural peculiarities of the old el language, and to semantic disturbances, which at the present low level of our development is inevitably the result of copying lower animals in our 'thinking', a pathological process for 'man'.
It will be well to explain at this point why I said that the Michelson-Morley experiment only assisted Einstein, and only seemingly proved the constant velocity of light. Historically, there is no doubt that the beginning of the theory of Einstein was suggested by, and had its physical basis in this experiment. In reality, as the whole of this present work about structure shows, the two issues are quite independent. The fact of the finite velocity of light has never been challenged, on the contrary it is becoming more and more solidly established, both empirically and theoretically, simply because an 'infinite velocity' has no meaning.
With the structural results of this present work, and the establishment of the fact of the finite velocity of light, the whole Einstein theory has a perfectly solid structural, linguistic foundation (1933). Nevertheless it is extremely gratifying that the latest, very important, and painstaking work of Doctor Roy J. Kennedy seems once more to add fundamental experimental support to the correctness of the Einstein theory.* From the point of view of structure, Einstein merely eliminated some primitive, perhaps even animalistic, remains of objectification which still lingered in the structure of our language of 'matter', 'space', and 'time'. These, being animalistic, were unfit for humans; vitiating not only our daily lives but science as well. (Eddington in The Mathematical Theory of Relativity, p. 196, uses the term 'pre-human' in a similar connection.)
It must be recalled that the definition of velocity is connected in a circular way with 'space' and 'time'. That is, in the definition of the relation of velocity, (v=s/t), 'space' and 'time', the definition of any one of our three terms depends upon our definition of the other two; whence there are many possible ways of verbal adjustment.
As we saw, the mechanical verbal principle of relativity with which we are all familiar was not structurally able to account satisfactorily for a similar relativity of optical and electrodynamic events. The older formulae of trans-
