Many insist that my neutral corpuscle is too material, and that something more ethereal is wanted, for it appears that ultra-violet light possesses many of the properties of _x_- and _gamma_ rays.... They propose therefore a quasi-corpuscular theory of light, _gamma_ and _x_- rays being included.... The light corpuscle which is proposed is a perfectly new postulate. It is to move with the velocity of light ... and to be capable of replacing and being replaced by an electron which possesses the same energy but moves at a slower rate, and, of course, it has to do all that the old light waves did. The whole situation is most remarkable and puzzling. So at this rate matter consists of molecules, as before; which consist of atoms, as before; which consist of electrons, as before--but may also in part or altogether consist of still more ethereal corpuscles _which are light_. It is but a step to the suggestion that the electrons consist of light corpuscles, standing to them as they stand to the positive or negative atom of matter. Then metals will be crystallized light. But whence the light corpuscles? How did they manage to get born in space? An answer to this question means a step-over from science into metaphysics. If and when we have reached the last line of matter we must begin to consider _consciousness_. Intellectual light, spiritual light--we think we are using only metaphors in those phrases. Possibly we are not. Physical light may be the last stage of higher lights. If physical light is divine thought-energy appealing to our sense, it may have passed down through higher stages at which it appeals only to mind and heart and spirit. If we think of Cosmic Spirit as pulsing its will and thought into that passive and uniform essence which will afterwards become active and differentiated matter, condensing and precipitating it into centers for evolutionary work, we must surmise that it is these intensely conscious centers that will subsequently be suns. Science would say that this condensation would already involve the liberation of heat, that the new center must at once be hot. But that is only true of condensing matter as we know it, matter which already contains latent energy. But the kind of matter we are considering now is what _will become matter_, has no possessions nor qualities till these are conferred on it by divine ideation and will. A sun at its first stage would be luminous only to a _spiritual_ cognition--that is, it would be charged with, and radiating, divine ideation. At the _very_ first it would not be even that; it would be but a _receiving_ center--for divine thought and will.
