And physics and chemistry is there anything of value along Theosophical lines of thought and investigation, which might aid our physicists and our chemists, puzzled at the subtlety of the forces with which they have to deal? Has it never struck some of the more intuitive physicists and materialists that there may be subtler senses which may be used for investigation of the subtler forces? That man may have in himself senses by the evolution of which he will able to pierce the secrets that now he is striving vainly to unveil? Has it never even struck a physicist or a chemist that, if he does not believe in the possibility of himself developing those subtler forces, he might utilise them in others in order to prosecute further his own investigations? They are beginning to to do that in France. They are beginning to now try to use those whom they call "lucid"; that is, people who see with eyes keener than the physical; they are beginning to use those in medicine, are using them for the diagnosis of disease, are using them for the testing of the sensitiveness of man, are beginning to use them to try to discover if man has any body subtler than the physical. And while I would not say to the scientific man: "Accept our theories," I would say to him: "Take them as hypotheses by which you may direct your further experiments, and you may go on and make discoveries more rapidly than you can at the present time." For there is many a clairvoyant who, put before a piece of some elemental substance, could describe it very much better than is done by your fractional analysis. And along other lines--chemical and electrical--surely there is something a little unsatisfactory, when a few years ago men told us that the atom was composed literally of myriads of particles, and during the last year it has been suggested that perhaps one particle is all of which an atom is composed. Might it not be wise to try to get hold of your atoms by sight keener than the physical, as it is possible to do, whether by the ordinary clairvoyant who is sometimes developed up to that point, or by an untrained sensitive whose senses are set free from the limitations of the physical brain, and from that sensitive try to gather something of the composition of matter which may guide you in your more scientific search? I realise that what one, or two, or twenty people see, is no proof for the scientific man; but it may give a hint whereby mathematical deductions may be made, and calculations which otherwise would not be thought of. So that I only suggest the utilising by science of certain powers that are now available, keener than those of the ordinary senses--a new sort of human microscope or human telescope--whereby you may pierce to the larger or the smaller, beyond the reach of your physical microscopes and telescopes, made of metal and not of intelligence showing itself in matter.
