What I want to do now [1885] is to connect vibrations not only with memory but with the physical constitution of that body in which the memory resides, thus adopting Newland’s law (sometimes called Mendelejeff’s law) that there is only one substance, and that the characteristics of the vibrations going on within it at any given time will determine whether it will appear to us as (say) hydrogen, or sodium, or chicken doing this, or chicken doing the other. [This touched upon in the concluding chapter of _Luck or Cunning_? 1887.] I would make not only the mind, but the body of the organism to depend on the characteristics of the vibrations going on within it. The same vibrations which remind the chicken that it wants iron for its blood actually turn the pre-existing matter in the egg into the required material. According to this view the form and characteristics of the elements are as much the living expositions of certain vibrations—are as much our manner of perceiving that the vibrations going on in that part of the one universal substance are such and such—as the colour yellow is our perception that a substance is being struck by vibrations of light, so many to the second, or as the action of a man walking about is our mode of perceiving that such and such another combination of vibrations is, for the present, going on in the substance which, in consequence, has assumed the shape of the particular man. It is somewhere in this neighbourhood that I look for the connection between organic and inorganic. The Universal Substance i We shall never get straight till we leave off trying to separate mind and matter. Mind is not a thing or, if it be, we know nothing about it; it is a function of matter. Matter is not a thing or, if it be, we know nothing about it; it is a function of mind. We should see an omnipotent, universal substance, sometimes in a dynamical and sometimes in a statical condition and, in either condition, always retaining a little of its opposite; and we should see this substance as at once both material and mental, whether it be in the one condition or in the other. The statical condition represents content, the dynamical, discontent; and both content and discontent, each still retaining a little of its opposite, must be carried down to the lowest atom. Action is the process whereby thought, which is mental, is materialised and whereby substance, which is material, is mentalised. It is like the present, which unites times past and future and which is the only time worth thinking of and yet is the only time which has no existence.
