'MATTER', 'SPACE', TIME"                          243
lication lead to many kinds of fanciful semantically harmful metaphysics. Since Einstein and Minkowski, the excellent term 'event' has been introduced into scientific literature. It is a term of such epoch-making semantic importance that it should become a term of daily use and should be introduced into elementary schools. Teachers do not perform their duties honestly or intelligently if they disregard such structural, linguistic, and semantic issues, which, as we have seen, are the central problem of all possible education.
Likewise, we have already seen that the chunk of nature which we call a 'pencil' is not 'matter' nor 'space' nor 'time', the terms being only terms. Is such el language structurally appropriate for the purpose of speaking about the world around us? It seems undeniable that such language is quite out-dated and very unsatisfactory. It introduces structurally an artificial elementalism of a verbal character, in spite of the fact that even the most elementary consideration shows that structurally the opposite is true; namely, that 'matter', 'space', and 'time' can never be experimentally divided. The term 'event' is precisely the term which does away with this old and vicious elementalism.
All that we deal with in the outside world involves indivisibly 'matter', 'space', and 'time'. Using the old language, there cannot be something somewhere at 'no time', or something at some 'time' and 'no where' or 'nothing' 'somewhere' at 'some time'. Everything which happens must be structurally represented as something, somewhere, at" some 'time'. If the structure of the world happened to be such that 'nothing' would happen 'nowhere' at 'no time', then we should have nothing to talk about, and all we would or could say would deal with our fancies. The four-dimensional language, which describes happenings structurally more nearly as we experience them, is precisely the language of 'events'. It should be remembered that in daily life we live by four-dimensional event-conditions. That is, the events which interest us are something, somewhere, and some 'time'. If we want two of our friends to become acquainted with each other, we invite them to our home. The appointment is in three dimensions in 'space' (to the left or to the right, forward or backward, up or down), and at a given hour. So we see that our daily life is lived in a four-dimensional space-time manifold, and we begin to appreciate the fact that science has lately caught up with such fundamental structural 'realities'. It must be noticed that the new four-dimensional space-time language does not, or should not, use the term 'matter' as we used it in the old way. In the new language, the bits of materials we deal with are connected analytically with the 'curvature* of this space-time manifold.
